Deep Grind – What Is Caffeine, and How Does It Work?

Caffeine is a naturally-occurring substance that is found in the seeds, leaves, and nuts of various plants – including coffee beans and tea leaves.

Caffeine is considered a stimulant drug – in short, this means that it speeds up the signals sent from your brain to your body.

Caffeine works primarily by binding itself to nerve receptors in our brain, often taking the place of adenosine – the brain chemical which makes us drowsy and want to sleep.

This causes our nerve cells to speed up, and this increase in activity signals to our bodies to produce adrenaline.

More adrenaline, as you can imagine, makes us more pumped!

Thanks to the adrenaline, your heart beats faster, your airway opens up, blood flow to your muscles increases, the liver releases sugar to the bloodstream, and your muscles tighten up.

In other words…

coffee = caffeine = adrenaline release = ready for action!

How To Drink Coffee Before A Run For Maximum Results

It’s been shown that caffeine helps boost performance – both in high-intensity sprint-style athletes and endurance athletes.

But – there are certain things to consider in order to optimise your morning coffee-fueled run.

Let’s check them out!

Time Your Coffee Right

You want to take your caffeine hit around 45 minutes before you start your run workout, according to this study – you have to wait some time for the coffee to hit your bloodstream, but if you wait too long after drinking caffeine before running or the effects will begin to fade.

How Much Coffee To Drink Before a Run

Studies have shown that 3-5mg of caffeine per kilogram of body weight is optimal to see the performance benefits while running.

So if you weigh in at 75kg, you want to aim for around 300 – 450mg of caffeine.

One Starbucks espresso shot has about 75 milligrams of caffeine (ref).

Whereas a regular cup of the store’s Pike Place medium-roast coffee has 155 mg.

in other words, a couple of cups of coffee is suitable for a 75kg person.

Don’t Drink Too Much

While it’s easy to get carried away with your cup of morning joe, be aware that higher doses do not lead to a performance improvement.

Instead, you’ll experience side effects such as dizziness, anxiety, heart palpitations, and inability to sleep well.

In other words, exercise control when preparing your coffee before a run!

Everyone’s Caffeine Tolerance Is Different

Something worth bearing in mind, especially if you’re a coffee rookie, is that everyone has different tolerances to caffeine.

If you’ve been drinking it daily for a while, you can expect to build up a resistance to small doses – and may need stronger stuff to wake you up.

Similarly, remember that your build affects your tolerance.

A triple espresso will have different effects on a 300-pound gorilla than it will a 100-pound grandma!

Coffee Doesn’t Seem To Dehydrate You

It’s common wisdom that coffee leaves you dehydrated – new studies however reckon that’s not true, and have shown there’s little evidence to support the claim.

If you are using coffee to boost your morning run, it’s worth remembering that even if the coffee doesn’t dehydrate you, the run will.

Replenish those fluids lost with water, and feel free to add electrolytes.

Just Tasting It Works

Recent studies in the Journal of Applied Physiology, Nutrition, and Metabolism have shown that the effects of caffeine can begin as soon as it enters your mouth.

Taste receptors signal to your brain that caffeine is coming, so the effects begin immediately.

This was proven in studies where the participants swilled a caffeine drink in their mouth before spitting it out.

Pre-Run Caffeine Can Even Help Your Post-Run Recovery

A study of participants in a 15k race showed that those who drank caffeine before the run had an enhanced anti-inflammatory response after the run – suggesting that caffeine can lower inflammation and help you recover faster.

How To Take Your Coffee Before a Run

Based on the research, my recommendation is as follows:

Take a cup of strong coffee 45 minutes before you go for a run.

Adjust the strength and quantity based on your tolerance and experience; if in doubt, start with a small, weaker coffee.

If you’re going running first thing in the morning, take the coffee the minute you wake up.

I recommend supplementing your coffee with some food to fuel your run – a banana is perhaps the perfect pre-morning run snack (read more on what to eat before running)

How Do You Take It?

Everyone has their coffee rituals.

For me, it’s usually a cup of Koffee Kult pre-ground beans done in a Bialetti Moka.

If I’m not in a hurry (which is unusual) I’ll get out my Aeropress and take time making the perfect cup.

  1. I so love my coffee. I am an avid coffee maker at home and coffee snob. I will never grab a cup of freeze dried anymore. Have not done that in over 15 years. My machine is big and loud and getting up early 5-5:30am for my runs is not conducive to noise for my young family. I do like your suggestion of the Moka pot or Aeropress though. I reckon I can get away with the kettle so i’ll look to grind the night before, store it appropriately so it does not oxidise and do a filter coffee in my V60. Willing to try that as I train for my first half-marathon.
