Why Life Stress Destroys Cycling Performance – DUCHY Coaching

At our DUCHY team meeting last week, we discussed the most common mistake we see when reviewing prospective clients’ training history. All of our coaches agreed—by a landslide—that the number-one error is this:

Not adapting training to accommodate life stress.

Many cyclists try to compartmentalise life stress and training stress, assuming one won’t affect the other. After a decade of coaching ambitious cyclists and high-performing individuals around the world, we can categorically say: that’s not how it works.

Life stress and training stress are deeply intertwined. And the science backs it up:

• Van Cutsem et al. (2017) found in a meta-analysis of 11 studies that mental fatigue consistently reduces endurance performance. Athletes felt more tired, rated sessions as harder, and performed worse—even when physiological markers like heart rate and lactate looked normal.

• Brownsberger et al. (2013) showed that cognitive stress before exercise lowers physical performance and increases perceived effort. In other words: your mind can compromise your output long before your body does.

The pattern we see everywhere

A cyclist has a stressful day, gets home, hits a hard session, and feels instantly better. Over time, this builds an implicit belief that training harder is the solution to feeling stressed.

And while that may work for an acute stressful moment, it does not work for chronic stress.

If you continue to push hard when work, family, or emotional load is high—believing training is the antidote—you will burn out. That’s when athletes end up needing extended time off the bike.

We see this often: cyclists whose wearable data says they’re “fresh,” yet in training they’ve lost the ability to dig deep. The sharpness, the drive, the willingness to suffer—it’s been drained by non-bike stressors.

The solution

If your data is saying yes, but your mind and body are saying no, trust your intuition and rest.

If sessions suddenly feel harder or progress has stalled, zoom out. What’s been happening away from the bike?

If life has felt heavy, demanding, or stressful, that’s your answer. You’re tired—so ignore the numbers on your Whoop, HRV app, or training algorithm.

Rest means rest—not a “recovery ride,” not a quick 30 minutes, not errands on foot.It means feet up. Sofa. Stillness.
