Caffeine has multiple benefits for runners, including reduced perception of effort, increased focus and concentration, and delayed time to exhaustion. In short, caffeine lets you run harder, longer, and faster before experiencing fatigue - boosting endurance by up to 6%.
Even across the full spectrum of 5K finish times - from sub-15 at the elite end through to around an hour at the back of the pack - the caffeine requirements of most athletes will be the same: a single dose of 80-100mg of caffeine taken near or just before the start of your race should be enough to carry you through, assuming you are chewing your caffeine as is optimal.
When you chew, caffeine is absorbed through membranes in the mouth directly into your bloodstream, bypassing your stomach. This results in a caffeine kick in as little as 5 minutes. For comparison, a cup of coffee, or a caffeinated running gel, can take up to 45 minutes to hit.
Caffeine also peaks in your bloodstream faster when you chew, reaching maximum concentration in as little as 40 minutes vs 80 minutes for drinking.
That means that, for most people, the time it takes for caffeine to peak in your bloodstream is the same or longer than it will take for them to complete a 5K. So there’s not necessarily any need to ‘top up’ your dose mid-race.
It’s important to note that, whilst caffeine is beneficial for 90% of us when it comes to performance, for around 10% of people it can actually have detrimental effects. It’s therefore important to try caffeine before using it in a race to see if it works for you.
What If I Want to Blow the Doors Off?
If you're going for a PB or just want to experiment, you could try an 'all-guns-blazing' approach, maximising your caffeine intake, by taking two doses of caffeine:
Dose one: 15-20 minutes before the start. This will be kicking in as you start the race.
Dose two: 5 minutes before the start. This will kick in mid-race and help you accelerate towards the finish.
Be warned: this is a very high dose, equivalent to two large cups of coffee. It will definitely have an impact! You should test your plan before race day to understand if it's right for you.
Why Caffeine Bullet?
Most runners aren’t making use of caffeine effectively, because the vast majority of caffeine products are packed with sugar and slow to act, relying on gut absorption which can take up to 25 minutes to kick.
Caffeine Bullets are formulated specifically for athletic performance. Tasty, lightweight, and easy on the stomach, they’re available in two delicious flavours.
