Sleep is the training session you're not doing

You do not get fitter while you train. You get fitter while you recover from training — and the single largest block of recovery in your week is the one you spend unconscious. Sleep is where the adaptation actually happens.
It's also the first thing most riders sacrifice. The 5am alarm for a pre-work trainer session sounds committed, but if it costs you 90 minutes of sleep every weekday, you are very likely training yourself backwards. Here's the case for treating sleep as a session, and how to fix the obvious things.
A 60-minute session that costs you 90 minutes of sleep is a bad trade almost every time. If you're routinely choosing between the alarm and the pillow, the honest answer is usually to train less often and sleep properly — a rider doing four well-recovered sessions a week beats the same rider doing six exhausted ones.
What sleep is actually doing
Growth hormone is released in deep sleep
The bulk of the repair work that turns training into fitness happens during slow-wave sleep, largely in the first half of the night. Cut it short and you cut the adaptation.
Glycogen is restocked overnight
Muscle fuel stores refill while you sleep. A short night means starting tomorrow's session already partly empty.
Perceived effort rises when you're tired
The same watts simply feel harder on poor sleep. Sessions get abandoned that your legs could actually have completed.
Immunity and illness risk
Chronic short sleep is associated with a higher rate of upper-respiratory infection — the classic reason a winter block falls apart in week five.
The wind-down that works
You can't force sleep, but you can remove the things that prevent it. This countdown covers the big ones:
Last big meal
Digestion competes with sleep. A large late dinner reliably worsens sleep quality.
Finish hard training
Late intense sessions leave core temperature and adrenaline elevated. Easy spinning is fine.
Screens down, lights down
Bright light late suppresses melatonin. Dim the room and stop doom-scrolling.
Cool the room
A cooler bedroom (roughly 16–19 °C) supports the drop in core temperature that initiates sleep.
Consistent lights-out
Regularity matters more than any single long night. Your body clock rewards predictability.
Six habits worth building
Aim for 7–9 hours
The commonly cited range for adults. Riders training hard often sit at the top of it — and genuinely need it.
Protect the wake time
If you must lose sleep, lose it at the start of the night rather than sleeping in erratically. A fixed wake time anchors the whole rhythm.
Nap if you can, briefly
20–30 minutes early in the afternoon. Long or late naps eat into that night's sleep pressure.
Watch caffeine timing
Caffeine has a long half-life. An afternoon coffee is still working at bedtime for many people, even if you fall asleep fine.
Don't drink alcohol to sleep
It shortens time to fall asleep and then wrecks the second half of the night — exactly the part that matters for recovery.
Add sleep before a big week
Banking sleep in advance is more effective than trying to repay a deficit afterwards.
Wearables give useful trends, but their per-night stage estimates are approximations, not measurements. Chasing a "sleep score" can create real anxiety about sleep, which is itself a well-recognised way to sleep worse. Use the weekly trend; ignore the nightly number.
How this changes your training
The practical consequence is that sleep should feed back into what you actually do the next day. Slept badly all week? That's a strong argument for moving the VO2 session and riding easy instead — see recovery is training for why that isn't slacking.
This is exactly the kind of adjustment a plan should make for you. Moveee adapts your block around what you've actually done and how you've been feeling, rather than holding you to a schedule written three weeks ago. And on the evenings when the session is on but the motivation isn't, Moveee Indoor lowers the barrier as far as it goes — open a browser tab, pair the trainer, and ride one of your own real routes with the targets already set. Free while in alpha, nothing to install, and it saves straight into your log.
The simplest advice on this blog
If you're training seriously and sleeping six hours, you will get more out of an extra hour in bed than out of an extra hour on the bike. It's free, it needs no equipment, and it's the one recovery intervention with genuinely overwhelming evidence behind it. Go to bed.

Recovery is training: sleep, easy days, and why rest makes you faster
You don't get fitter when you train — you get fitter when you recover from it. Here's how sleep, easy days and rest turn hard work into actual speed.
Morning or evening: does the time you train change what you get?
Peak power really is higher in the late afternoon, and the effect is much smaller than the effect of actually doing the session. What circadian rhythm does to performance, and why the honest answer is "whenever you will keep turning up".
How to train indoors: turning trainer time into real fitness
An hour on the trainer can be worth ninety minutes on the road — or completely wasted. Here's how to structure indoor sessions so every minute you spend in the pain cave counts.
The off-season: how long to rest and what to keep doing
Two to four weeks of light, unstructured riding, one short hard session kept, and not past six. The detraining studies say what you lose, how fast, and which losses are cheap.
Big-gear, low-cadence work: strength on the bike, or just slow?
Fifty rpm up a climb in a gear you can barely turn feels like it must be building something. What torque intervals actually train, what the evidence says about transfer to real power, and the knee-load caution nobody puts in the session description.
The 15-minute core routine every cyclist should be doing
A strong trunk stops your hips rocking, stops power leaking sideways and keeps your lower back quiet in hour three. Six exercises, no equipment, twice a week.
Indoor training with heart rate only (no power meter, no problem)
No power meter, no smart trainer — just a heart-rate strap? You can still train properly. How to find your threshold heart rate with one honest 30-minute test, set five zones from it, structure a week around what HR measures well, and work around what it doesn't (lag, drift and hot rooms).
Ice baths after riding: recovery, or throwing away your adaptation?
Cold water genuinely restores short-term function, and there is reasonable evidence it dulls the long-term adaptation you trained for. The resolution is not "never" — it is knowing which of those two you need this week.
Over-unders: the interval that teaches you to ride through lactate
The session that turns "I blew on the third climb" into "I was there at the top" — and one of the most frequently botched workouts in cycling. Four versions in order of difficulty, and the four ways riders ruin them.
Cycling as you age: what changes after 40, 50 and 60
Maximum heart rate falls, recovery slows and muscle needs defending — but the decline in trained riders is roughly half what it is in the sedentary. What changes decade by decade, and what training protects most.
Fast twitch, slow twitch: what fibre type means for how you should train
You cannot know your own fibre composition without a needle, the proxies people use are rough, and "train to your type" is weaker advice than it sounds. What is genuinely established about fibre types, and the handful of training decisions it should actually change.
Eating to recover from a big week, not just a big ride
A camp or a hard block leaves a hole one recovery shake will not fill. Carbohydrate scaled to the load for several days, protein spread across each day, and the signs you have slipped into under-fuelling.
