I love drinking coffee with my family at a lazy breakfast, on a cold day exploring San Francisco, or most of all at the end of a long ride with friends. Coffee tastes amazing and smells glorious; oh, it can also make you faster on the bike.
How it Works
It’s no secret, the world loves coffee largely because it contains caffeine. As the most widely used drug in the world , caffeine has a host of health benefits . When it comes to endurance performance, caffeine has a long history of making cyclists faster . Exactly how caffeine improves cycling performance is up for debate [2, 4], but here’s a good place to start. Caffeine:
- Impacts the Central Nervous System (CNS) by competing with adenosine receptors .
- Increases β-endorphin release .
- Reduces RPE (Rate of Perceived Exertion) .
- Improves reaction time and alertness .
- Decreases reliance on glycogen utilization .
For the most part, there’s no other legal supplement more studied and proven to make you faster. From coffee to soda, you have a lot of choices. Check out the chart below to see how caffeine stacks up in different products. For an even more comprehensive list, click on the chart.
Classic research suggests the biggest performance improvements come from anhydrous (pill or powder form) caffeine . If you’re comfortable popping pills before a race, anhydrous caffeine might be your best bet.
On a personal level, even though the caffeine content is the same in pill form as in many beverages, drinking a few cups of coffee feels a bit less desperate and a lot less tweeker than swallowing pills behind the reg tent of an office park crit. Fortunately, new research has shown coffee to be nearly as effective as caffeine [10, 11]. I’m sticking to coffee. So how much should you drink before a ride or race?
How Much to Drink?
First we need to understand how much caffeine it takes to boost your watts. Research pegs this number between 3-6 mg/kg bodyweight . In practical terms, a cyclist weighing 70kg (154lbs) should aim for at least 210mg of caffeine before a ride or race.
3 mg/kg is a great starting point for getting a performance jolt without negative side effects (anxiety, restlessness, and headaches) . If you reference our chart above, 3 mg/kg is equivalent to about 1-2 cups of 12 ounces of strongly brewed coffee. We’ve got the quantity down, so when do you drink it?
When to drink?
To start with, the more frequently you drink coffee, the more desensitized you become to its performance benefits . Try to hold off for 4 days before an important ride or race. Can’t do that? Even 24hrs without caffeine is better than nothing . What about race day?
Research shows caffeine reaches peak plasma concentration about 45-60 minutes after ingestion . Finish off two cups about 1 hour before your start time and you should be locked and loaded. Maybe.
Responders and Non Responders
While caffeine seems to be effective for most cyclists, some don’t get a performance boost at all . In short, there appears to be a gene that influences how quickly you metabolize caffeine. Fast metabolizers show greater performance gains from caffeine while slow metabolizers might actually get slower after consuming caffeine.
The takeaway? Caffeine is probably going to make you faster, but there’s a chance it might actually hurt your performance. As with every other training intervention or supplement, test it out and see for yourself.
- If you’re looking for a safe and legal supplement to help you get faster on the bike, caffeine is your surest bet.
- Coffee is about as good as caffeine pills at boosting cycling performance.
- It takes at least 3 mg/kg of caffeine to improve performance. Lower doses don’t do much.
- 2 cups of strongly brewed coffee is a good reference point for the 3mg/kg caffeine threshold of a 70kg cyclist.
- Try abstaining from coffee for 4 days before an important event. If you can’t hack that, try at least 24hr.
- Drink your coffee 45-60 minutes before the start of your race.
- There’s a chance caffeine could make you slower. Test it out before you settle on a regular race routine.
