Recovery Week Cycling, How Often and How Much to Cut

James. You're listening to the WattPlan Podcast, and I'm James. Day to day it's family, work, building WattPlan and chasing the odd podium, and somewhere in the gaps I read a slightly silly amount of sports science. This week, the week everyone skips. Three weeks on and one off is practically gospel, so is it actually backed by anything, and how much should you really cut? Lyra, who's an AI and our research voice, has been through the trials, and every study is linked in the show notes.

Lyra. Ha, the week everyone skips and then wonders why the next block feels flat. Straight answer. Every third or fourth week is the convention, and it comes from coaching tradition more than trials. On how much to cut, WattPlan's recovery week takes the hours down by about a third, keeps at least two full rest days, and keeps every ride easy.

James. Hang on. Three on, one off, and you're telling me nobody's tested it?

Lyra. Not head to head. We looked for a randomised trial comparing two hard weeks and one easy with three and one, in cyclists or any endurance sport, and found none. So the spacing is a sensible habit, not a proven number. What the trials do show is how quickly hard training can turn into lost performance.

James. Go on then. How quickly?

Lyra. Faster than most riders would guess. The clearest study is Shona Halson, Asker Jeukendrup and colleagues, from 2002, in the Journal of Applied Physiology. Eight endurance cyclists did two weeks of normal training, two weeks of intensified training, then two weeks of recovery. After the hard fortnight, their simulated time trial went from 59.4 minutes to 65.3. Maximal power dropped from 338 watts to 319. [2]

James. Six minutes slower. That's enormous.

Lyra. It is, and maximal heart rate fell by 9.3 percent as well. The authors' conclusion is the line to remember. Overreaching can show up after as little as seven days of intensified training with too little recovery.

James. Overreaching. Define that for me, because I think people use it to mean just a bit tired.

Lyra. Right, so functional overreaching is a short-term fall in performance that's followed by improvement once you've recovered. Non-functional overreaching is what follows when training and recovery stay out of balance. A recovery week is the scheduled part of that recovery, so you plan it before sessions start failing, not after.

James. But surely some overreaching is the point? Dig deep in the block, then bounce back higher. That's the whole idea.

Lyra. That's exactly what the third study tested, and the answer isn't what the dig-deep crowd wants. Aubry and colleagues, 2014, in Medicine and Science in Sports and Exercise. Thirty-three trained male triathletes. Twenty-three did three weeks of overload, ten trained normally, then everyone had a four week taper. After the overload, eleven were functionally overreached, performance down with high fatigue. The other twelve were just tired, with no drop in performance. [3]

James. And who came out on top?

Lyra. The tired but not overreached group. They reached the highest peak through the taper, above both the overreached group and the ones who'd trained normally. So pushing on until performance actually fell bought nothing extra. Train hard enough to be tired, then unload before the sessions start failing.

James. Okay, so that's when. Now how much do I actually cut? Half? A quarter? Everything?

Lyra. The nearest guide is a 2007 meta-analysis in Medicine and Science in Sports and Exercise by Laurent Bosquet and colleagues. It pooled 27 studies of tapers in competitive sport and found the biggest benefit when training volume came down by 41 to 60 percent, while intensity and how often they trained stayed the same. Two weeks was the best length. [1]

James. But a taper's before a race. That's not the same as an easy week in the middle of a block, is it?

Lyra. You're right, and that's the catch. Bosquet looked at tapers before competition, and we found no pooled analysis of mid-block recovery weeks. So it's the nearest guide, not a direct answer. What it does back is riding less rather than stopping, and that's the part a recovery week keeps.

James. So if I'm hearing you right, I don't stop riding. I just ride less of it. How much less, in practice?

Lyra. For a rider doing eight hours in a loading week, WattPlan's recovery week comes out at about five hours. Each ride is about a third shorter, at least two days are full rest, and all of it is easy. That's a smaller cut than the tapers in that analysis, because it's a pause in the middle of a block, not the run in to a race. That's how WattPlan plans it.

James. And what about the chart? Because my Fitness line drops and I panic.

Lyra. Ha, the classic. WattPlan's Fitness is a 42 day weighted average of your daily Load, and Fatigue covers seven days. So a lighter week pulls Fitness down a little and Fatigue much further, which lifts Form. That's arithmetic on the Load you rode. How your next hard session goes tells you far more about your legs than the line does.

James. Love it. Let's split it out by who's listening. If you're new to this, what does a recovery week look like?

Lyra. If you're new to structured training, keep it simple. After three weeks of steady riding, make the fourth one lighter. Shorter rides, at least two rest days, and all of it at an easy, chatty pace. Then judge it by how the following week feels, not by whether the easy week felt productive.

James. And if you train with power or heart rate?

Lyra. Then let the plan place it. WattPlan puts a recovery week every fourth week of each training phase, so in a long plan you can see four or five loading weeks in a row where one phase runs into the next. Expect the hours down about a third and no hard session. And if sessions start failing, or a heavy week at work lands on top of training, ask the Coach to cut the week back rather than pushing on.

James. And if you race, or you're building towards a target event?

Lyra. If you race, the Aubry result matters most. Hard blocks are fine, but the best peak came from being tired, not from being overreached. So don't push a block on until your power drops. And the week before a taper doesn't need its own recovery week, because the taper is the unload.

James. How does WattPlan actually build one, then?

Lyra. Every fourth week of a training phase is a recovery week. Its Load is set from the Fitness you carry into it, so Fitness dips only a little, and the dip scales with how fit you are. No hard sessions, and every ride, the long one included, is about a third shorter than usual. At least two days are full rest. A hard club ride on your schedule stays in, with advice to sit in, and an event you've added keeps its full length.

James. And what can't the studies tell us here?

Lyra. Quite a lot. No trial has tested how often a recovery week should come, or how deep it should be, in amateur cyclists. Bosquet's numbers come from tapers, Halson had eight riders, and Aubry's were male triathletes. Most people across these studies were men. And older riders are often told to take a lighter week more often, but we found no cycling trial that tested it.

James. Right. So what's the homework this week?

Lyra. Three things. One, find your next recovery week in the plan, and don't skip it to chase Fitness. Two, when it comes, ride it as written, hours down about a third, at least two rest days, every ride shorter. Three, keep the whole week easy, then judge it by your first hard session after it, not by the Form line.

James. Okay, in my words. Three hard weeks, then a third off the hours, two rest days, all of it easy, and stop staring at the Form line. And if the block's going badly, ask the Coach to cut the week back.

Lyra. That's it. In a hard block, tired is the goal and overreached isn't. The recovery week is where you plan the recovery that tired depends on.

Lyra. The full article and every study we mentioned are on the WattPlan blog, linked in the show notes.

James. And if you want a plan that's built around the time you've actually got, that's what WattPlan does. Thanks for listening.
