8-Week Half Marathon Training Plan: Essential Info

Can you train for a half marathon in 8 weeks? – Yes, absolutely.

However…

If you are relatively new to running, you’ll much be much better with one of our longer training plans that build up your mileage gradually and come with a lower risk of overtraining.

Who Is This Training Program For?: 

Runners who have run a half marathon in the past and want to ‘dust off’ their half marathon chops. 

If you’re looking to train for a half marathon in 8 weeks for an upcoming race, then this is the plan for you.

How Long?: 

8 weeks.

It includes 2 mid-week runs, to be performed at a comfortable pace, one tempo run, and one long-slow run each weekend to build your max mileage. The schedule also includes one cross-training day per week and two rest days.

Training Breakdown – What Will Your Weekly Schedule Consist Of?

Training Runs

These are your classic training runs; do them in the mornings or after work, at a comfortable, sustainable pace.  

These runs help add mileage to your training schedule and get your body used to running far!

Tempo Runs (optional)

A tempo run is a training run done at your target half-marathon pace, if you have one.

When you’re ready, you can also check out our Half Marathon Pace Calculator to help plan your race speed based on your finish time goal.

Cross Training

Each week includes a cross-training day; although these aren’t mandatory, I highly recommend them.

Why?

Cross-training is meant to work on your cardiovascular health and strengthen some of the muscles weakened through running.

Recommended cross-training exercises include bodyweight exercises, light gym work, swimming, yoga, pilates, and cycling!

Long Runs

You should be factoring in one long, slow run every weekend. These runs are all about increasing your endurance gradually.

Remember to take it easy during them, don’t push things, and don’t worry about walking breaks – it’s all about building up that time on your feet.

Prerequisites: Who Is This Plan For?

An 8-week plan is not a beginner plan — it’s a compact build for runners who already have a solid running base. You should be comfortable running 4-5 miles at an easy pace and ideally running 3-4 times per week already. If you can run a 10K without too much trouble, you’re in good shape to start this plan.

If you’re newer to running or your weekly mileage is under 10 miles, consider our 12 week half marathon training plan instead — the extra 4 weeks make a significant difference in how safely you can build up.

The Taper: Don’t Skip It

In an 8-week plan, the taper is short but essential — typically just the final 7-10 days. Your last long run should be about 10 days before race day, after which your mileage drops by roughly 40-50%.

With a compressed timeline, the temptation is to squeeze in extra training right up to race week. Resist this. The fitness you have 10 days before the race is the fitness you’ll race with — no last-minute long run will improve your performance, but it can easily leave you fatigued or injured on race day.

Fueling for Your Half Marathon

For runs under 60-75 minutes, water alone is usually sufficient. But your long runs (and race day) will push past that threshold, so you’ll need a fueling strategy.

Start practicing mid-run fueling during your longest training runs. Most runners do well with an energy gel or a few energy chews every 45-60 minutes after the first hour. On race day, aim to take on 30-60g of carbohydrates per hour after the first 45 minutes. Aid stations will have water and often sports drink — decide in advance which you’ll use and practice with it.

The day before the race, eat a carb-rich dinner but don’t overdo it. On race morning, eat your usual pre-run meal 2-3 hours before the start. Whatever you eat, it should be something you’ve tested during training — race morning is not the time for experiments.

5 Tips for Racing Your Best Half Marathon

1. Start conservatively. The first 3 miles of a half marathon should feel almost too easy. If you’re breathing hard before mile 4, you’ve gone out too fast. Aim to run your first 5K about 10-15 seconds per mile slower than your target pace.

2. Break the race into thirds. Miles 1-4 are about settling in and finding your rhythm. Miles 5-9 are the working middle where you lock into your target pace. Miles 10-13.1 are where you make your move and push toward the finish. This mental framework keeps the distance from feeling overwhelming.

3. Use aid stations wisely. Practice grabbing cups on the run during training. On race day, slow to a fast walk through the station if needed — the 5 seconds you lose is nothing compared to spilling water down your front and missing your hydration entirely.

4. Dress for mile 3, not mile 1. You’ll warm up quickly once you’re moving. If you’re comfortable standing at the start line, you’re overdressed. A good rule: dress as if it’s 10-15°F (5-8°C) warmer than the actual temperature.

5. Trust your training. Eight weeks is enough time to prepare for a half marathon if you’re consistent. Your long runs have covered the distance, your body has adapted, and the taper has sharpened your fitness. When doubt creeps in on race morning, remember: you’ve done the work.
