So, you’ve followed your training plan to a T, strength trained religiously, prioritized sleep and nutrition, and sacrificed more social engagements than you can count in preparation for your ultramarathon.

And trust me — it’s absolutely worth it.

Whether it’s your first ultra or your twentieth, a 50K or a 100-miler, crossing that finish line always makes the sacrifice worthwhile.

Most runners spend months preparing the obvious pieces of the puzzle: long runs, speed workouts, strength training, recovery, and weekly mileage. But many still arrive at race day stressed, scrambling, and underprepared for the countless smaller details that can shape the outcome of an ultramarathon.

Because while your training is critical, your race-day strategy matters just as much.

Yes, the fitness is there. You’ve prepared your body for the distance. But ultramarathons are rarely decided by fitness alone. Fueling, pacing, gear, aid station strategy, mindset, problem-solving, and managing the inevitable highs and lows can all make or break your race experience.

Planning for these details ahead of time can be the difference between merely surviving your ultra and truly enjoying it.

As an ultramarathoner and coach, I’ll walk you through the often-overlooked aspects of ultramarathon race strategy so you can set yourself up for the best possible experience — whether your goal is a podium finish, a personal best, or simply earning that first ultra finish line.

Why Your Ultramarathon Race Strategy Matters

Creating a race strategy is essential for running a successful ultramarathon. You want to be prepared for anything that may arise during the race and to have a well-thought-out plan in place long before race day.

Registering for an ultramarathon is the first major step, but many runners overlook the importance of researching the race itself before committing. Every ultra is different, and understanding the specific demands of your event can dramatically impact your experience and performance.

Most races provide a detailed runner’s guide—often a lengthy PDF packed with information about the course, terrain, elevation, aid stations, weather conditions, cutoff times, gear requirements, and logistics.

Use this guide to your advantage.

Knowing what to expect allows you to prepare intelligently for the unique challenges of endurance racing. The more familiar you are with the course and race details, the fewer surprises you’ll face on race day.

In the following sections, we’ll break down the key elements of a typical ultramarathon runner’s manual and how to use that information to build an effective ultramarathon race strategy.

Know Your Route

If you’ve looked at ultramarathon race results, you’ve probably noticed that finishing times can vary dramatically from one event to another—even when the races are the exact same distance.

Unlike a road marathon, where finish times are generally more predictable, estimating an ultramarathon finish time is much more complex.

Factors such as technical terrain, elevation gain and loss, weather conditions, altitude, and even aid station logistics can significantly affect your pace and overall race time.

Because of this, one of the first steps in building an effective ultramarathon race strategy is estimating how long the race will realistically take you—and roughly how much time you expect to spend between aid stations.

This information is essential for planning your fueling, hydration, pacing, and gear needs throughout the event. In many ways, these estimates become the foundation of your entire race-day strategy.

To build your ultramarathon race plan, you’ll want to answer the following questions:

#1: Is your race one big loop, various loops of the same trail, alternate loops, out and back, or point to point?

There are advantages and disadvantages to each of these route types.

For example, one big loop usually has several aid stations along the way; various loops that return to the same meeting point will bring you back to the same aid station various times.

An out-and-back will also bring you back to the start line as your finish line, and you will pass aid stations twice: in the first half on the way out and in the second half on the way back.

A point-to-point takes more planning, as it’s the only variation in which the start and finish lines are at different locations.

The important thing is to know which one is yours so you can plan accordingly. You will need to plan logistics, such as how to get to the start line, how to be picked up from the finish line, and everything in between. 

This brings us to our following questions:

#2: How many aid stations are there throughout the race? Where are they located, and what will they be stocked with?

Knowing exactly where you will run into your aid stations allows you to plan how much fuel and hydration you will need to carry from station to station.

If the aid stations are 5K, 10K, or 15K apart, there will be a big difference in what you have to carry with you.

How many gels or energy bars will you pack, and will you need one 500 ml bottle, two, or a 2-liter hydration bladder? Will you be able to run with just a handheld or a waist belt? Or will you need to bring a full hydration vest?

The most important thing is never to be stuck without fuel.

Calculate what you will need as precisely as possible based on your previous long-run speeds compared to the distance between aid stations. Also, consider the terrain, elevation, and gain, and that you may slow down as you advance in the race.

Also, the amount of fuel you will have to carry with you will depend on our next question:

#3: Will you be refueling with what is offered at the aid stations, or do you need to bring your own nutrition and hydration for the entire race?

As you have been fueling with specific items during your long runs and figured out exactly what works for you, the worst thing you could do is change that nutrition and hydration strategy on race day. 

You’ve worked too hard and come too far to have gastrointestinal problems along the way.

If you are lucky enough that the aid stations will have your specific products available, you can plan on carrying less and refueling at each aid station.

If you cannot refuel at the stations by eating and drinking their products, you either need to carry more things with you or have your items waiting for you with a crew member or in a drop bag at the designated aid stations. 

Again, ensure you have enough fuel to get from one aid station to the next, and always bring along a bit more, just in case. We don’t want anyone to dehydrate or experience burnout along the way.

#4: How many drop bags are you allowed to have, and where can you access them?

Many ultramarathons allow runners to use drop bags throughout the race. A drop bag is a small bag of personal items you leave at designated aid stations along the course so you can access supplies when you pass through.

Depending on the event, you may be allowed just one drop bag placed near the halfway point, or several positioned at key aid stations throughout the course. In looped races, you may return to the start/finish area multiple times and have access to the same bag all day.

Used wisely, drop bags can make a huge difference in your comfort, efficiency, and overall race execution.

Here are some of the best ways to use your drop bags strategically:

  • Store nutrition and hydration for the next section of the course so you can carry less between aid stations
  • Pack extra layers for changing weather conditions or colder nighttime temperatures
  • Leave a headlamp and spare batteries if part of your race extends into the dark
  • Include an extra pair of shoes and socks in case your feet get wet, muddy, or blistered
  • Pack foot care supplies such as blister kits, lubricant, tape, or anti-chafing products
  • Bring backup essentials like sunscreen, electrolytes, salt tabs, gloves, hats, or medications
  • Include comfort items such as wet wipes, a toothbrush, or a favorite snack to boost morale late in the race

One of the biggest mistakes runners make is underpacking their drop bags. Remember—you don’t have to carry these items with you, so it’s often better to be slightly overprepared than to miss something important when conditions change.

A few additional drop bag tips:

  • Label your bag clearly with your name, bib number, and aid station location
  • Use bright colors or ribbons so your bag is easier to spot in a large pile
  • Pack items in separate ziplock bags to stay organized and protect gear from rain or spilled fluids
  • Practice efficiency—know exactly what you need from your bag before race day to avoid wasting time at aid stations
  • Plan for multiple scenarios, especially in mountain races where weather and temperatures can shift quickly

If you’re fortunate enough to have crew support, they may even have your drop bag ready and waiting when you arrive at the aid station, saving valuable time and reducing stress.

Understanding where your drop bags are located—and how long it will take you to reach them—is also an important part of estimating your time between aid stations and building your overall race strategy.

#5:What is the terrain and elevation profile?

When building your ultramarathon race strategy, few things are more important than understanding the terrain and vertical gain of your race.

Two races may be the same distance on paper, yet feel completely different depending on the course profile. A runnable gravel course with rolling hills is a very different experience from a mountainous race filled with steep climbs, technical descents, mud, rocks, river crossings, or exposed ridgelines.

Before race day, study the course map and elevation profile carefully. Break the race down section by section so you understand what type of terrain and climbing you’ll face throughout the event.

This allows you to plan strategically:

  • Where you can comfortably run
  • Where power hiking is the smarter choice
  • Which climbs require patience and energy conservation
  • Where you can take advantage of smoother terrain or runnable descents
  • Which sections may take longer than expected due to technical footing

Understanding the course also helps you estimate how much time you’ll spend between aid stations so you can properly plan your fueling and hydration.

Terrain matters more than many first-time ultrarunners realize.

Rocky, muddy, sandy, or highly technical trails can dramatically slow your pace compared to groomed dirt paths, gravel roads, or asphalt. Add significant elevation gain and loss, and your pace may vary wildly throughout the day.

Because of this, ultramarathon pacing looks very different from road marathon pacing.

In a marathon, runners often aim to maintain a relatively steady pace. In trail ultras, however, successful pacing is usually based on effort, not pace. Your speed will naturally fluctuate depending on the terrain, climbs, descents, weather, altitude, and fatigue.

A few additional tips when studying your course:

  • Look for the longest climbs and descents and mentally prepare for them
  • Pay attention to altitude, especially if you live and train at sea level
  • Check whether sections are exposed to sun, wind, or cold temperatures
  • Read race reports from previous participants to learn where runners typically struggle
  • If possible, preview sections of the course beforehand or study videos and photos online

The more familiar you are with the terrain, the more confidently and efficiently you’ll be able to race on the day.

#6: What weather conditions can you expect?

Weather can make or break an ultramarathon.

Being underprepared for the conditions can quickly turn a strong race into a survival exercise. Cold temperatures, rain, wind, heat, humidity, or sudden weather changes can dramatically affect your pacing, fueling, hydration, comfort, and overall safety on the trail.

If temperatures are cold and you don’t pack the proper gear, even simple tasks can become difficult.

Frozen or numb hands make opening gels, refilling bottles, or adjusting equipment frustrating and time-consuming. Wet clothing combined with wind or altitude can also rapidly lower body temperature and increase the risk of hypothermia.

On the other end of the spectrum, hot and humid conditions require a completely different strategy. Higher temperatures increase sweat loss, elevate heart rate, and force you to slow your pace to avoid overheating and dehydration. Electrolyte intake and hydration become even more critical in these situations.

No matter the forecast, your race strategy should adapt to the conditions.

In the days leading up to the race, monitor the weather forecast closely and prepare for a range of possible scenarios—especially in mountain races where conditions can shift quickly throughout the day.

A few smart weather-planning tips:

  • Pack extra layers, gloves, hats, or rain gear even if the forecast looks favorable
  • Prepare for large temperature swings between nighttime and daytime sections
  • Use drop bags to stage weather-specific gear throughout the course
  • Bring anti-chafing products and dry socks for wet or rainy conditions
  • Adjust your hydration and electrolyte plan if heat or humidity is expected
  • Wear gear you’ve already tested in training—race day is not the time for new clothing or shoes

It’s almost always better to bring more gear than you think you’ll need. You can leave extra items in a drop bag or with your crew, but you can’t magically create warmth, dry clothes, or hydration once you’re deep into the race.

Prepared runners adapt. Unprepared runners suffer unnecessarily.

#7: What required equipment must you have on you at all times during the race?

Some race organizers compile a list of required equipment. I understand that this can be frustrating for some ultrarunners trying to run light and want to avoid carrying items they know they will most likely not use.

However, organizers do this for your safety, not just to make you carry more stuff.

For those trying to come in first, think of it this way: your competitors also need to carry the same required equipment, so you are all on an even playing field. 

If you are worried about weight, there are plenty of different gear options. Yes, usually the lighter, the more expensive, but if those extra grams mean a lot to you, you can cut a lot out by purchasing a lighter jacket, hiking poles, headlamps, and whatever else you may be asked to bring. 

Double-check to ensure you have all the required equipment because racer checks are usually done before an ultramarathon. If you don’t have the requirements, you may be penalized with time or, even worse, disqualified.

Crew and Pacers

#8: Does your race allow you to have a crew?

Most ultramarathons allow racers to have a personal crew to help them throughout the race. If you have ever watched the pros fly through the 100-miler Western States or UTMB’s Mont Blanc, it’s quite a team effort for some, as it looks like they are stopping at a NASCAR pit stop.

A crew can be a massive advantage in your ultramarathon race strategy by saving you loads of time at aid stations.

Crew can have your new running vest loaded and ready to go before you even get there. They can also assist in any emergencies that may come up, whether it’s changing your sneakers out or leading you to a bathroom asap!

If you are racing up front, your crew can let you know how far ahead or behind your competitors are, helping you adjust your pacing strategy. 

Also, knowing your friends and family are waiting for you at specific points throughout the race helps with motivation. It puts a big old smile on your face when you come through. This will lift your spirits and help get you through those tough times.

#9: Does your race allow pacers?

In many ultramarathons, pacers can play a huge role in a runner’s success—both physically and mentally.

Whether you’re racing for a podium finish or simply trying to make it to the finish line of your first 50-miler or 100K, having the right pacer beside you can provide a major advantage late in the race when fatigue, discomfort, and mental lows begin to set in.

For competitive runners, a pacer can help maintain effort, monitor pacing, and prevent costly mistakes early in the race. They can encourage you to stay focused, keep moving efficiently, and avoid burning too much energy trying to match competitors too soon.

For newer ultrarunners, pacers often become even more valuable.

Most races allow pacers to join during the later stages of the event—when runners are typically exhausted, emotionally drained, and more vulnerable to poor decision-making. Having another person beside you during these difficult miles can completely change your race experience.

A good pacer can:

  • Help keep you moving during low moments
  • Remind you to eat, drink, and stay on schedule
  • Navigate technical or difficult terrain with you
  • Keep you mentally engaged and focused
  • Monitor your mood, energy, and physical condition
  • Prevent long aid station stops or unnecessary sitting
  • Offer encouragement when things inevitably get tough

Sometimes, simply having someone there to talk to—or even just quietly share the trail with—can make all the difference.

However, every race has different pacing rules, so it’s important to review the race manual carefully beforehand.

Be sure to check:

  • Whether pacers are allowed at all
  • At which mile or aid station pacers can join
  • How many pacers you’re permitted to use
  • Whether pacers need to register or wear a bib
  • If pacers are allowed to carry gear or provide assistance

If you plan to use a pacer, communicate clearly with them before race day. Discuss pacing expectations, fueling reminders, gear needs, and how you’d like them to help if you begin struggling physically or mentally.

The best pacers don’t just keep you company—they help you stay calm, consistent, and moving forward when the race gets hard.

How To Fuel For An Ultramarathon

#10: Do you have your pre-, during-, and post-race- nutrition and hydration strategies planned out?

One of the most important parts of any ultramarathon race strategy is your nutrition and hydration plan. Even the fittest runners can struggle—or completely fall apart—if they fail to fuel properly.

Ultramarathons place enormous demands on the body, and maintaining steady energy intake throughout the race is essential for performance, decision-making, muscle function, and overall survival late in the event.

Ideally, your fueling and hydration strategy should already be practiced and refined throughout training. Race day is never the time to experiment with new products, foods, or hydration methods.

Here’s how to approach each phase of your ultramarathon fueling strategy:

Pre-Race 

In the final two to three days before your ultramarathon, gradually increase your carbohydrate intake to maximize glycogen stores and ensure your muscles are fully fueled heading into race day.

Focus on familiar, easy-to-digest foods that you’ve successfully eaten during training. Avoid trying “healthy” but fiber-heavy meals right before the race, as excessive fiber can lead to stomach issues once you start running.

Good carbohydrate-rich options include:

  • Pasta
  • Rice
  • Potatoes
  • Bread or bagels
  • Oatmeal
  • Pancakes
  • Low-fiber cereals

Hydration is equally important. In the days leading up to the race:

  • Drink fluids consistently throughout the day
  • Include electrolytes regularly, especially in hot or humid conditions
  • Avoid overhydrating with plain water alone, which can dilute sodium levels

The goal is to arrive at the start line well-hydrated—not bloated or dehydrated.. 

The Morning Of The Race

Ultramarathons often begin very early in the morning, but it’s still important to eat a proper breakfast approximately 2–3 hours before the start so your body has enough time to digest and absorb the fuel.

Stick with foods you know work well for you.

Some common pre-race breakfast ideas include:

  • Toast or bagels with jam or peanut butter
  • Oatmeal
  • Bananas
  • Rice or pancakes
  • Sports drink with carbohydrates

Because breakfast is usually eaten hours before the start, many runners also take in a small carbohydrate source—such as an energy gel, chews, or a few bites of food—about 10–15 minutes before the race begins.

During The Race 

Your in-race fueling strategy is one of the biggest determinants of ultramarathon success.

A good starting point for carbohydrate intake is:

Carbohydrates per hourbody weight in kilograms (grams/hour)\text{Carbohydrates per hour} \approx \text{body weight in kilograms (grams/hour)}

For example, a 70 kg runner may aim for roughly 70 grams of carbohydrates per hour, though exact needs vary depending on intensity, experience, gut tolerance, and race duration.

Fuel sources can include:

  • Energy gels
  • Sports drink with carbohydrates
  • Gummies or chews
  • Energy bars
  • Potatoes
  • Rice balls
  • Sandwiches

As races get longer, many runners benefit from mixing sweet and savory options to avoid flavor fatigue and nausea.

A few important fueling principles:

  • Start fueling early, before you feel hungry
  • Eat small amounts consistently rather than large amounts infrequently
  • Set reminders or use aid stations as fueling checkpoints
  • Continue fueling even if you temporarily lose your appetite

One of the most common ultramarathon mistakes is waiting too long to eat. Once you fall significantly behind on calories and hydration, it becomes very difficult to recover.

Hydration needs vary enormously depending on the temperature and humidity, your sweat rate, altitude, and individual physiology.

During training, practice estimating your sweat rate in conditions similar to your race so you can build a realistic hydration plan.

In general:

  • Aim to replace a large percentage of the fluids lost through sweat
  • Include electrolytes regularly, especially sodium
  • Drink to thirst while staying proactive

Both dehydration and overhydration can negatively affect performance and health during an ultra.

Simplify Your Fueling Strategy

The longer and more competitive the race, the more important efficiency becomes.

Use products and systems that are:

  • Easy to carry
  • Easy to open
  • Easy to consume while moving

Pre-mixed hydration bottles, clearly labeled drop bags, and ready-to-go nutrition can save valuable time and reduce stress at aid stations.

The easier it is to fuel, the more likely you are to stay consistent deep into the race.

Post Race

Once you cross the finish line, recovery begins immediately.

Try to consume a recovery drink, protein shake, or carbohydrate-and-protein-rich meal within the first 20–30 minutes after finishing. Early nutrition helps replenish glycogen stores, support muscle repair, and reduce the severity of post-race soreness and fatigue.

Even if you don’t feel hungry immediately after the race, getting calories and fluids in early can significantly improve recovery over the following days.

A smart fueling and hydration strategy can be the difference between fading late in the race and finishing strong. Train your gut, practice your plan, and treat nutrition as seriously as your mileage.
