The opening weekend of racing on the Tour de France has been fiery in additional methods than one. On the bikes, riders have not did not placed on a present, however the greatest battle many riders confronted was one with Mother Nature, fairly than one another. As the race started in Florence, a high-summer heatwave blasted Italy, turning it into an oven.
Mark Cavendish was the very best profile rider to undergo, vomiting en route and, on the end, being given an iced towel by a ready press officer. It was already going to be a troublesome day for the British sprinter with 3600m of climbing on the highway to Rimini, however the 36°C warmth did not assist.
Light winds on Sunday did little to dissipate the warmth, as an alternative turning the Adriatic coast right into a convection oven. The climate may need been excellent for the hoards of holidaymakers in close by seaside cities, however among the many crowd of followers at first in Cesenatico, groups had been frantically equipping their riders with cooling aids.
Ice vests had been a standard sight, ice-slush drinks had been downed, popsicles had been plentiful, and virtually each rider began the race with a minimum of one ice sock down their jersey. Riders had been even stuffing water bottles down their jerseys for a second’s respite from the roasting they had been getting.
To get an understanding of the science behind the cooling methods, in addition to an perception into every crew’s methods, Cyclingnews spoke to a couple groups at first of stage 2 in Cesenatico.
Ahead of the race, the first focus was on acclimatisation for all groups. The distinction that warmth adaptation could make is critical. Speaking to Cyclingnews earlier than the Tour, Red Bull-Bora-Hansgrohe’s Head of Performance, Dan Lorang, gave an instance of the potential advantages of warmth acclimatisation.
“Your threshold is say 400 watts. In scorching circumstances, it may very well be that the edge drops to 370 for instance. With warmth adaptation coaching, you in all probability can carry the edge again as much as 390 or 95 someplace there, so you’ll be able to shut that hole.”

If this had been an gear change, a saving of 20 to 25 watts is one thing that groups would pay vital quantities of cash to realize, so the good thing about acclimatisation, after which subsequent cooling technique, is large. It’s no shock to see groups investing in new applied sciences and workers assist on this space.
“The world’s warming up, that is clear,” started Ineos Grenadiers DS Zak Dempster matter-of-factly.
“The physique’s response to the warmth is one thing that is been written about quite a bit, and it is a part of our preparation course of, due to the optimistic impact it has on the coaching stimulus to be extra prepared. Our guys do numerous warmth coaching, numerous them have warmth chambers at residence, which they go in, and that is a giant a part of our course of.”
At Team DSM-Firmenich-PostNL, the Head of Science, Narelle Neumann, defined that this course of begins round three to 4 weeks previous to the race for her riders.
“For some riders, they do it on the bike so shall be carrying additional garments, as a result of we wish that additional stressor whereas they’re coaching. For different riders, it is higher to do it after, throughout restoration, in order that it does not compromise the coaching. For these riders, they’re going to both do a sauna session or a scorching tub session. The key right here is we additionally monitor how a lot they sweat in order that they will hold hydrating in order that it does not compromise the subsequent day.”
The preparation part does not cease till the very second the race begins, and even in the course of the week main as much as the race, with Florence such a furnace, the riders would have been adapting and acclimatising proper till the final second.
“When we acquired right here to Italy, within the days the coaching days beforehand, we had been utilizing all of our scorching climate protocols,” Neumann continued. “The drinks we adapt for warm climate in order that they will drink extra with out having an excessive amount of carbohydrates, additionally ice socks.
“I feel yesterday was a terrific instance of what we are able to do within the race to make it possible for all the riders are actually well-fueled and stayed cool. We had, I feel, greater than 10 bottle factors, with numerous assist from workers with bottles, ice slushies and ice socks. It sounds slightly bit conventional, nevertheless it’s nonetheless the simplest solution to cool.”
Dempster additionally identified that in relation to cooling, issues needn’t be unnecessarily difficult. While Red Bull-Bora-Hansgrohe’s riders use medical-grade cooling compression boots, the Ineos Grenadiers method is extra easy.
“We have just a few units, however there’s nothing difficult on the finish of the day. It’s identical to a bath of chilly water. The identical as when you’re chilly, the perfect, most confirmed factor to do is to get in a shower of scorching water, and that helps you heat up.
“So we have gone again. You see these fancy new ice vests on a regular basis, and the fellows with ice socks and all these issues, however that is extra of a sensation factor really. If you set the ice sock in your again, you are really not gonna drop your physique’s temperature.
The Ineos Grenadiers crew has actually been utilizing ice vests and ice socks each earlier than and after the primary two levels of this yr’s Tour, however as with most groups, the will to carry the core temperature down earlier than a race supplies a minor efficiency acquire, because it takes longer for the physique’s temperature to climb to these detrimental ranges.
The common core temperature for people is round 97°F (36.1°C) to 99°F (37.2°C). Power output can drop by 5% per diploma Celcius improve (Racinais et al).
“If you will get to the race cool, that is the very first thing, after which all you are really doing is you are combating a dropping battle in overheating.”
Interestingly, to an extent, Norelle disagrees with Demspter’s take. She believes ice socks do help in decreasing the core temperature, however she’s eager to confess it is “slightly little bit of each.”
She defined that “numerous the science reveals that cooling across the base of your head, round your neck, is the simplest solution to hold your core physique temperature low,” later including that there are different methods that ‘trick’ the physique into feeling cooler, even when the bodily impact is nonexistent.
“I feel the ice, actually proven from the analysis, actually does assist cool the core physique temperature. You can do a variety of checks to truly take a look at that however then the water on the pinnacle is also only a feeling of refreshment, eliminating sweat, but additionally staying cool in that means.
“Menthol is one usually that folks will use. It’s that cool, refreshing style in your mouth, so though it could not change issues, it provides you a psychological refresher. Those are methods that may work in that means, however we actually need them as a secondary.”
Once the day’s racing is completed, whereas most of the groups have an ice tub contained in the again of a van – as seen at Ineos Grenadiers, UAE Team Emirates and Astana Qazaqstan, to call simply three – Red Bull-Bora Hansgrohe’s method is a bit more excessive tech.
Team supervisor Ralph Denk, alongside press officer Stefan Flessner, defined that the crew use a chilly remedy wrap system from the American model, Game Ready. Working in an identical solution to restoration compression boots, these pump chilly water via the wrap to chill the physique.
They can even work with heat water, however after all that might be torturous in temperatures resembling these. It’s primarily a medical product, and it is available in numerous styles and sizes for various physique elements, however the boots are utilized by the crew, presumably for the extra good thing about compression on the riders’ hardest-working muscle groups.
DSM’s method is extra centered on hydration and a gradual return to a standard temperature, fairly than surprising the physique with ice or any high-tech answer. Of course, this is also a funds constraint for the crew, who haven’t got fairly as deep pockets because the groups combating for GC.
“There’s been some analysis taking a look at pool baths, ice baths, issues like that,” Naumann defined. “And really, the analysis reveals that that is not essentially completely efficient, as a result of it may be fairly a temperature shock for the physique. What we actually deal with is hydration. They’ll have restoration drinks and chilly drinks, after which we simply step via the restoration meal protocol. So after the remainder, it is actually about hydration, and clearly the air con actually, actually helps as nicely.”
