Reverse periodisation: intensity in winter, miles in summer

The traditional cycling year is so entrenched that most riders have never questioned it: long slow miles through the winter, intensity added in spring, sharpness in the weeks before the event. It came from professional riders in mild climates with unlimited time, and for them it makes complete sense.

For an amateur in a northern winter with a job, it can be exactly backwards — and reverse periodisation is the alternative that says so.

The idea

Flip the order. Do the intensity when your time is short and the weather is bad, because intense sessions are short and work perfectly well indoors. Build the volume when the days are long and the roads are dry, because long rides need daylight and decent weather.

The load still rises through the year. What changes is which quality gets built first.

Why it works better than it sounds

The objection is obvious: surely you need a base before you can handle intensity? In the strict sense — a rider who has never ridden a bike should not start with VO2max intervals — that is true. For a returning rider with years of history behind them, it is much weaker than it sounds. Their base does not vanish over one winter; detraining: how fast you lose fitness covers just how durable it is.

The second point is that intensity builds aerobic fitness too. High-intensity work is not purely anaerobic — it drives central adaptations as well, which is why riders who only do short hard sessions still get aerobically fitter. It is less efficient at it per hour of misery than steady riding, but three hard hours a week beats zero good hours pretending to be five.

Who it suits

A winter week, reversed

• Two hard indoor sessions. One VO2max — 30/30s are ideal for this — and one threshold or over-under session. Both fit in an hour including warm-up.
• One longer ride at the weekend. Whatever the weather and daylight allow. Two hours is fine. This keeps the aerobic machinery awake without demanding a heroic winter.
• One or two genuinely easy spins. Short, indoors, no targets.
• Strength work. Winter is when it fits, and it does not compete with a plan built on short sessions — strength training for cyclists covers the case.

Then, from late February, the long rides get longer while the intensity holds at maintenance. By May you are doing what the traditional plan was doing in January, except outdoors, in daylight, with fitness you built in the dark.

The honest limitations

• It is not a licence to skip volume forever. If your event is five hours long, you will need long rides at some point. Reverse periodisation moves them, it does not delete them — see durability for what those hours are actually buying.
• Intensity year-round is a real risk. The plan works because the hard weeks are followed by recovery weeks. A rider who does two hard sessions every week from November to August without a down week will not make it to August.
• Early-season events fit poorly. If your goal is a March sportive, the traditional order is the right one — you cannot build the volume after the event.

It only works if the indoor hours are good ones

The whole approach rests on the winter sessions actually happening. That means the trainer setup has to be something you will use on a Tuesday when it is dark and you would rather not — a fan, a screen at eye level, and a session that starts without ten minutes of software wrangling. Pain cave setup covers the physical side.

Moveee Indoor runs in a browser tab — nothing to install, pair the trainer and go — and rides your own saved routes in 3D while ERG holds the interval targets. For a plan that lives or dies on whether you do the Tuesday session, removing the friction between deciding to ride and riding is worth more than it sounds. It is free while in alpha.
