What do pro riders do on Tour de France rest days?
No such thing as a rest day, Team Qhubeka NextHash tweeted. Thats right, after suffering in the mountains the riders might get a well-deserved day off from the racing itself, but you cant get the pro riders off their bikes. Pro riders are packing in active recovery rides to stretch out their legs, but its not just that on the rest day to-do list. Refuelling, scouting out the next stage, dealing with journalists, sponsor duties, a lot is going on. Okay, there are lie-ins and massages to enjoy too, but rest days arent just a full day of relaxing and lazing about. That said, there is still a significant reduction in the intensity and the volume that day... because all the other days are even crazier! Lets take a look at how much easier the pro riders took the rest day and how much recovery they needed. The EF Education Nippo team have partnered with Whoop for insights into personalised biometrics including heart rate variability, resting heart rate, respiratory rate and sleep performance, to optimise recovery for each rider in the team. Weve been able to measure training load for years now, but that is only four to five hours of the day. WHOOP gives us insight into the other 20 hours of the day. Individually, riders have been able to make changes to their routines and prioritise recovery in a data-driven, actionable manner, says Kevin Sprouse, the head of medicine at EF Education Nippo. This graph above shows the data Whoop collection for the EF Education team across the first nine stages of the Tour and into day 10, the rest day. Looking at the blue top line first, the day strain was really high  day strain is on a scale from zero to 21, and it measures the total cardiovascular load experienced across the day  hitting over 20 for six of the stages, all of which had over 1,600 metres of climbing, whereas on the recovery day this dropped down significantly to 13.2. Now taking a look at the recovery percentage, after accumulating 546km with 10,969 metres of climbing in the legs across the three days before the rest day, that red 28% on the day off racing says it allthat recovery day was definitely needed. To dip to that lower day strain doesn't mean not riding at all though. To spin out the legs, the Jumbo-Visma lads for example headed out for a two-hour ride in Tignes on 5 July for the first rest day of 2021s Tour. Wout van Aert clocked an average speed of 33.5km/h (20.8mph) for a 42km (26 mile) spin with 474m of climbing. Teammate Mike Teunissen uploaded his ride to Strava too but in his case complete with heart rate data and power readings. Across the ride, he had an average heart rate of 82bpm and a max of 118bpm. He averaged 130 watts, with one 20 minute block sitting around the 235-watt mark. Whats the furthest youve ridden on a Rest Day?, Ineos Grenadiers tweeted, along with pictures of the team heading out for their ride. A ride out for the guys this morning in Tignes.

At least G managed a lie-in first.

The riders are also having fun testing unreleased shiny kit from their sponsors while stretching their legs on the bike. Israel Start-Up Nations Michael Woods was spotted riding a new solid five-spoke disc brake wheel with shallow rims from Factor Bikes in-house brand Black Inc.  (Theres no point trying to look out for these wheels in the Tour de France peloton though as UCI regulations do not permit their use in group competition.) Physical as well as mental recovery is needed though, and food can play a role in both of these areas. The day before the rest day the Trek-Segafredo team were treated to burgers and chips, tour style, of course as a rest day tradition. They nommed a healthy version, consisting of fresh bread, meat with 5% fat, fresh tomatoes, avocado and low-fat cheese, with some salad and roast potato on the side. Also notably, instead of mayo, ketchup or regular sauce they had beetroot mousse as studies have shown that beetroot has the potential to reduce muscle pain and inflammation if eaten post-workout. Its feeding their body after a hard day and also giving them something for the mind is quite important, the teams chef shared in a video on Twitter. Then there are sponsor shout-out duties to do too, showing youre putting released sponsored products to good use. This time Israel Start-Up Nations Michael Woods was filmed having SpiderTech's kinesiology tape applied to his legs for aiding recovery. "To have @SpiderTech as a sponsor is such an advantage for us!"

I call it my five-hour ache; after about five hours of riding I often get a bit of pain in the patellar tendon particularly and so I really find the Spider Tech knee tape really helps for that. Were doing both legs today because its a recovery day and I really shocked the system the last two days in the mountains. It was really challenging hard racing and it was also challenging conditions with the rain, and I find that this synthetic stuff really helps with reducing inflammationit just gets you feeling a bit better.  As well as stretching the legs on the bike, there are some serious tools for helping out the muscles. Dorian Godon of AG2R Citroens was having a little bit of rest, while the team's physiotherapists worked some magic with EMEs Polyter Evo. AG2R says the portable device is mainly used for recovery sessions, easing trauma in case of crashes and chronic trauma following muscles tendon hyperstimulation. Last but not least, there are journalists like us, ruining the relaxation by pestering the riders for answers to questions. Enric Mas and Miguel ngel Lpez carried out this duty for Team Movistar in a live-streamed press conference as part of their rest day.
