WHO THIS IS FOR
IS THIS YOU?
The cyclist who drinks coffee but has never optimised their timing
You drink coffee every morning but time it from habit, not performance strategy.
The rider who wants to use caffeine for racing or key sessions
You want to use caffeine deliberately as a performance tool rather than just a morning habit.
THE ROADMAN VIEW
The Roadman view
Caffeine is the most evidence-backed legal performance aid in cycling. Anthony has said it repeatedly and the research backs him up without qualification — the 2–4% improvement in time-trial performance is as robust as any finding in sports nutrition. It is not a placebo. It works by reducing the perceived difficulty of effort, which means you produce more power at the same level of discomfort.
The practical mistake most riders make is drinking coffee every morning regardless of whether they are training hard that day, and then wondering why it does not feel like it does much when they actually race. Caffeine tolerance is real — daily habitual use significantly reduces the performance effect. The riders who get the most from race-day caffeine are the ones who manage their intake strategically: moderate on easy training days, deliberately higher on hard days and before races.
Timing is easy to get wrong too. The peak plasma level hits around 45–60 minutes post-ingestion, so a coffee at the café before a sportive — if you arrive at the start 30 minutes later — means you are still climbing toward peak effect at the gun. Time it so peak effect lands when the race or hard effort starts.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Caffeine performance researchMeta-analyses in endurance sport
Caffeine is among the most consistently replicated findings in sports performance science. A dose of 3–6mg/kg body weight improves time-trial performance by 2–4% on average, reduces RPE at submaximal intensities, and improves both aerobic and anaerobic power output. These effects are present even in habitual users, though the magnitude is smaller.

Coffee is embedded in pro cycling culture for a reason — the performance evidence is genuine. At team level, caffeine use is planned around racing schedules, with deliberate reductions before major events to reduce tolerance and maximise race-day effect.

PRACTICAL APPLICATION
DO THIS WEEK
Time caffeine intake 45–60 minutes before the hard effort starts
For a sportive starting at 8am, take your caffeine at 7–7:15am. For an interval session starting 45 minutes into a ride, take it before you leave home. The peak performance effect arrives around 60 minutes post-ingestion and lasts 2–3 hours.
Dose at 3–6mg/kg for performance use
For a 70kg rider: 210–420mg, which is roughly 2–4 espresso shots or one to two strong filtered coffees. Start at the lower end if caffeine-sensitive. More than 6mg/kg adds side effects — anxiety, jitteriness, GI distress — without meaningful extra performance benefit.
Consider a caffeine reduction before key events
If you drink 3–4 coffees daily, reduce to one or two in the week before a target race or key session. Tolerance reduction amplifies the race-day performance effect. You do not need to eliminate caffeine entirely — a modest reduction is enough.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKEDrinking coffee at the same time every morning regardless of training.
FIXTime caffeine to peak for your hard sessions. A morning coffee 90 minutes before an afternoon interval session barely contributes. Take it 45–60 minutes before the work.
MISTAKETaking more caffeine than 6mg/kg hoping for more benefit.
FIXThe performance dose ceiling is around 6mg/kg. Above that, side effects increase and performance benefit plateaus. Dose intelligently, not aggressively.
MISTAKEUsing caffeine daily in high doses and expecting a race-day effect.
FIXTolerance blunts the performance benefit. Manage intake strategically — lower on easy days, moderate on training days, targeted on race days.
