HOW DOES AGEING AFFECT CYCLING PERFORMANCE?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

VO2max declines approximately 7-10% per decade in sedentary adults after 40, but trained cyclists lose only 3-5% per decade if they maintain structured high-intensity work. Research by Pollock et al. (2015) found that amateur cyclists who continued racing into their 70s preserved cardiovascular function equivalent to adults 20-30 years younger. What declines most is anaerobic power, muscle mass, and recovery speed — not aerobic capacity itself, which responds to training stimulus at any age.

KEY TAKEAWAYS

VO2max declines 3-5% per decade in trained cyclists — less than half the rate in sedentary adults.
Anaerobic power and sprint capacity decline faster than aerobic fitness after 50.
Muscle mass loss (sarcopenia) accelerates without resistance training, reducing peak power output.
Recovery time between hard sessions lengthens, requiring more strategic programming.

WHO THIS IS FOR

IS THIS YOU?

The rider hitting 40 and wondering what changes

You have heard that everything goes downhill after 40 and want to know what actually declines and what you can control.

The competitive masters cyclist

You are racing against the clock and want to understand which physiological changes to prioritise in your training.

The rider returning after a long break

You stopped riding for 10 years and want to know what is realistic for your age group.

THE ROADMAN VIEW

The decline is real but it is wildly overstated by people who stopped training and blamed their birthday. A 55-year-old who trains consistently will outperform a 35-year-old who does not — and the research backs that up. The King's College London study found lifelong cyclists in their 70s with immune systems, muscle mass, and cholesterol profiles of people decades younger.

What actually changes: your ceiling drops slightly each decade, your recovery takes longer, and your anaerobic power fades faster than your aerobic engine. That last point matters — it means you lose your kick before you lose your endurance. The tactical implication is clear: masters cyclists win on sustained power, not on sprints.

The controllable variables are training consistency, high-intensity stimulus (do not drop intervals just because you are older), resistance training to offset muscle loss, and recovery management. Get those right and the age-related decline becomes a gentle gradient, not a cliff.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Prof Stephen HarridgeProfessor of human and applied physiology, King's College London
In a landmark study of 125 amateur cyclists aged 55-79, those who maintained regular cycling showed preserved muscle mass, immune function, and cholesterol profiles. The research concluded that many age-related declines attributed to ageing are actually caused by inactivity.
Dr Hirofumi TanakaExercise physiologist, VO2max and ageing researcher
VO2max declines at roughly half the rate in endurance-trained individuals compared with sedentary populations. Critically, the inclusion of high-intensity interval training — not just steady-state volume — is what preserves VO2max most effectively in masters athletes.

PRACTICAL APPLICATION

DO THIS WEEK

Keep one VO2max session per week
VO2max is the physiological variable most responsive to training at any age. Include one session of 4-6 intervals at 90-100% of max heart rate, 3-5 minutes each, with equal recovery. This is the single most important workout for slowing age-related aerobic decline.
Add resistance training twice per week
Leg press, step-ups, single-leg press, hip thrusts, and calf raises. Three sets of 8-12 reps. Progressive overload every 2-3 weeks. This is the primary defence against sarcopenia and the power loss that comes with it.
Increase recovery time between hard sessions
After 40, allow 48-72 hours between high-intensity sessions. Two hard days per week with adequate recovery produces better results than three hard days with insufficient recovery. Monitor resting heart rate and HRV to calibrate.
Prioritise protein and sleep
1.6-2.0 g/kg/day protein to support muscle maintenance. 7-9 hours of sleep — growth hormone, which declines with age, is released primarily during deep sleep. These are not marginal gains; they are the foundation.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKEDropping all high-intensity work because of age.
FIXHigh-intensity training is what preserves VO2max. Reduce the frequency (2 per week, not 3-4) and increase recovery, but never eliminate intensity entirely.
MISTAKETraining the same way as 20 years ago.
FIXRecovery demands change. A programme that worked at 35 will break a 55-year-old. Adjust volume and recovery — the principles stay the same but the dosage changes.
MISTAKEComparing current performance to personal records from decades ago.
FIXBenchmark against your age group, not your 30-year-old self. A 3% per decade decline means a 55-year-old at 90% of their peak is performing exceptionally.

FAQ

FREQUENTLY ASKED QUESTIONS

At what age does cycling performance peak?

Road cycling performance typically peaks at 28-32 for professionals and 30-40 for amateurs. The peak is later for ultra-endurance events, where experience and pacing skill compensate for declining top-end power.

Can I still improve FTP after 50?

Yes, particularly if you have not been training structured. Many riders set new FTP personal bests in their 50s after switching from unstructured riding to a periodised programme with targeted intervals.

Why do I get injured more easily now?

Tendon stiffness increases with age, collagen turnover slows, and recovery from microtrauma takes longer. Warm-up properly, progress training loads conservatively, and include mobility work to reduce injury risk.

Does hormone replacement therapy help performance?

Testosterone replacement therapy can improve lean mass and recovery in hypogonadal men, but carries cardiovascular risks and is banned in competitive sport. Discuss with an endocrinologist rather than self-prescribing.

Is there a point where training does not help any more?

No. Studies of athletes in their 80s and 90s show continued physiological response to training stimulus. The rate of improvement slows and the ceiling lowers, but the body adapts to training at every age.

Should I change my bike position as I age?

Flexibility loss often requires a slightly more upright position — shorter stem, higher bars, or a shorter top tube. Get a bike fit reassessment every 2-3 years after 50 to ensure your position matches your current range of motion.
