Most cyclists train too hard. Not occasionally — consistently. Every ride at a pace that feels like it counts, every session pushed because anything less feels like wasted time. Eight weeks ago I took on a lad who was doing exactly this, burning himself out between groups, nearly quitting the sport, and not understanding why he wasn't getting faster.
Key Takeaways
The reason most cyclists plateau has nothing to do with not working hard enough. It's because they train hard all the time and never give their body a different stimulus to adapt to. I see this constantly — riders doing every session at a pace they'd describe as 'solid', Strava segments half-cocked, never easy enough to recover, never hard enough on the days that actually matter. The lad I mentioned at the start of this episode was doing exactly that. Too fast for the slow group, too slow for the fast group, grinding away in no man's land and wondering why nothing was changing. The fix is zones. You do a threshold test, you set your zones from the result, and now you have a precise prescription — not 'ride hard', not '22 km/h up the hill', but 60 minutes in zone 2 with two 15-minute blocks at zone 4. That's a session. That's a language a coach can use and an athlete can follow.
The adaptation principle is the bit people miss. Your body is smart. You stress it, it adapts, it stops responding to that same stress. I worked on a building site at 16 and came home destroyed every evening for weeks. Lad beside me doing the same work was off playing five-a-side after his shift. He'd adapted. The work wasn't stimulating him anymore. That's periodization — you change the stress before the body gets too comfortable with it. The problem is when cyclists go hard every day, they never let the easy sessions be easy, so the hard sessions can't be hard enough to actually drive adaptation. Zones fix that. They give you the language to train the right system on the right day, and stop you grinding yourself into the ground on days that are supposed to be recovery.
