“It’s one thing we’re trying into and has nice potential, however that’s so far as it goes on the minute.”
“It’s one thing we’re trying into and has nice potential, however we are able to’t reveal extra.”
No reply. The three guidelines of Synthetic Intelligence (AI) Membership when Cyclingnews requested skilled groups for his or her suggestions on what seemingly each business sees as a game-changing expertise. Skilled biking, swarming with information factors for each attainable metric, would appear a chief candidate for AI intervention. However secrecy and aggressive benefit dominated. Till we got here throughout a Belgian firm referred to as Brailsports, which appears to be in collaboration with ProTeam Lotto Dstny. So, we contacted Brailsports and lo and behold, the bogus shutters weren’t up. “We’d be delighted to speak,” communication specialist Pieter Van Nuffel instructed us. Glorious. Time to see how biking coaching, diet and expertise will change – and are altering – by means of using AI…
Impressed by Crew Sky
First issues first, an introduction. “We’re named after Sir Dave Brailsford,” says Steven Latré, head of AI at Imec. Brailsports is a spin-off of Imec, a world-leading nanoelectronics R&D hub whose headquarters are in Leuven. They’re a non-profit organisation and have 5,500 researchers worldwide. “Our founders had been on a gravel experience and got here up with the title as he’s the person who introduced science to biking.
“The AI and biking thought arose round 4 years in the past,” Latré provides. “Researchers then labored on the mission earlier than we collaborated with Lotto Dstny on the primary model of the platform final 12 months. They’ve more and more used our dashboard, with this 12 months’s Tour de France the spotlight of our link-up to this point.”
Extra exactly, the 18th stage the place Victor Campenaerts racked up his first Tour de France stage victory. It’s been extensively reported that the Belgian spent 9 weeks at altitude within the build-up to the Tour, uncommon for a rider in search of stage success. It’s much less well-known that Campenaerts turned AI potential right into a victorious actuality.
“A number of days earlier than that stage, the dashboard was signalling a excessive degree of fatigue and stress,” says Latré. “The staff took that on board and collectively made the choice to instruct Victor to ease off. It offers you a day by day view of each rider that’s really personalised.”
Which sceptics would possibly say is just like the likes of main energy software program Coaching Peaks? “First off, we do combine with Coaching Peaks and import all the info,” says Latré. “However how is the coaching rating calculated? In essence, an educational years in the past had athletes examined in a managed surroundings and made a mathematical mannequin out of their findings, deciding that’s how health and fatigue work. And there’s actually worth in that.
“However at Brailsports, you’ll obtain values of health and fatigue which are extra distinctive to you. Our AI mannequin offers you an actual perception into the coaching impulses of the person, serving to to see should you’re edging towards overtraining or on the verge of a efficiency breakthrough. It’s all about optimising an enormous quantity of coaching information of that exact rider.”
The Brailsports dashboard sucks in swathes of metrics which are then merely introduced to each rider and coach. As a snapshot, you’ve got lactate-threshold predictions that might result in a change in coaching load; day by day wellness metrics like coronary heart charge variability to measure stress; and a fatigue-to-fitness ratio rating.
It may not sound seismic however keep in mind, it’s this extra particular evaluation of coaching and potential physiological and efficiency adaptation that’s seen energy meters turn into omnipresent within the skilled area. If AI could make these coaching and race selections much more exact, and extra correct, in principle, there’ll be a higher probability of decreasing sickness and delivering peak efficiency.

The Exercise Wizard
After all, AI is just pretty much as good as whoever has labored on the machine-learning fashions within the first place. To that finish, Brailsports has labored with specialists at Ghent and Antwerp universities, whereas its co-founders are professors in train physiology and cycle teaching. They stress it’s not only a staff of software program builders. As does Paul Laursen of the AI teaching platform Athletica.
Laursen is a extremely adorned sports activities scientist and coach of greater than 30 years. He was the previous lead efficiency physiologist for Excessive-Efficiency Sport New Zealand in the course of the London and Rio Olympic cycles and has had over 140 papers printed. Athletica AI was born in 2020 and now encompasses a staff of knowledge and sports activities scientists, plus a high-profile investor and tester, Alistair Brownlee, who gained Olympic gold in triathlon at London and Rio.
Laursen is at present working with knowledgeable biking staff, however he stays guarded about who. It doesn’t take lengthy to drop the guard, a fast search on the Athletica web site reveals its ProTeam VF Group-Bardiani CSF-Faizanè. The location consists of an evaluation of 20-year-old Giulio Pellizzari’s try and win the sixteenth stage of this 12 months’s Giro d’Italia. You may dig into the element right here however, suffice it to say, he was handed by Tadej Pogačar with 700m to go, although held on for second.
A standout metric is their novel methodology of quantifying a session, named Exercise Reserve. Just like Brailsports, it hoovers up swathes of coaching and race information, on this case, to provide an perception into how a lot gasoline stays within the tank relative to what riders have achieved previously. This, says Laursen, works in tandem with their Exercise Wizard.
Now, that is the bit that basically might pique a rider’s curiosity, particularly a leisure rider as Athletica is offered to beginner athletes, utilizing information from Garmin or Strava.
“A rider would possibly comply with a coaching plan, however they may search selection,” says Laursen. “That’s the place the Wizard is available in. It’ll change your session, however nonetheless hit the identical physiological targets and coaching masses as the unique choice based mostly in your final six weeks of coaching. That ensures you’ll by no means burn too many matches. These are issues that will make a coach’s mind harm however the Athletica AI can do this in seconds.”
Fuelling precision
So, AI has the potential to make wasted coaching miles a factor of the previous. It’s the identical with energy. Visma-Lease a Bike has been on the forefront of fuelling expertise for years, thanks ostensibly to having a software program firm (Visma) as a co-sponsor since 2019 and a grocery store chain (Jumbo) as a co-sponsor between 2015 and 2023. The outcome was the Diet Prediction Mannequin.
Many months upfront of the Tour de France, the diet staff would analyse the route and make a collection of dietary predictions for every stage based mostly on who’s going to experience the Tour and a rider’s physiology. For every stage and the potential position and purpose of every rider, the staff then predicted their energy output and depth of effort, and so might predict power expenditure and carbohydrate use. With the arrival of AI, which additionally accounts for climate situations, Visma suggests the accuracy of diet predictions from 52% to 82%.
Then there’s Hexis, a chunk of software program that matches dietary must coaching output, serving to riders to periodise fuelling each day. They’re at present working with quite a few WorldTour groups and riders together with Bob Jungels.
“We’re not technically AI; we’re extra an clever machine that follows sure guidelines,” says Dr Sam Impey, Hexis co-founder and former lead nutritionist at British Biking. “It’s educated to make selections I’d make however on a a lot bigger scale.”
Cyclingnews has performed round with the system and it’s a usable app that utilises a traffic-light system to tell whether or not you’re under-fuelled, over-fuelled or spot on. It reveals the macronutrient breakdown of every little thing you eat to information carbohydrate, protein and fats consumption. If you happen to’re a TrainingPeaks person, you possibly can hyperlink the 2 apps, Hexis integrating this kilojoules-burnt info into your day by day dietary equation.
Impey says it’s notably helpful on the WorldTour degree the place you might need one rider competing on the Tour whereas one other’s on an altitude camp. “Traditionally, these riders coaching at altitude in all probability wouldn’t take pleasure in any help from the nutritionist as a result of they’re specializing in the Tour riders. With a expertise like Hexis, they’ll take the guesswork out of what they’re doing.” In a weight-based sport, the efficiency advantages are clear.
Uno-X additionally utilise meals expertise and realise the advantages of AI. “One of many limitations on the diet facet is that it’s static info,” says James Moran, the staff’s nutritionist. “That’s not excellent as we are able to all see the rise in velocity over the [past] few years. The following step could be to include AI to calculate race speeds going ahead, which might have an effect on power expenditure, which we might then use to formulate an much more particular diet plan for every rider.”
Arguably, consider what goes into making an elite rider and staff and AI has the potential to refine. Selecting the very best eight riders for the Tour, pinpointing a rider’s actual hydration wants within the warmth, the proper drag-reducing gear and clothes set-up relying heading in the right direction profile… We all know WADA (World Anti-Doping Company) is funding analysis into AI and doping.
“And you’ll actually see AI getting used to optimise sure supplies and shaping for higher aerodynamics,” Latré says. “Additionally, I do know there’s present work AI fashions to detect sure issues of safety alongside a parcours. There are sometimes crashes within the peloton. After all, generally it’s right down to the behaviour of the cyclists, however generally it’s right down to the design of the route. You’ll be capable to pinpoint the doubtless harmful sections with AI.
“Rider recruitment will profit, too, particularly for expertise identification. You’ll be capable to evaluate the performances extra precisely of a rider repeating the identical hill in Colombia in comparison with a rider within the UK, even when the hills are utterly completely different profiles.”
Potential downsides
The outcome? Ever-greater race speeds? Probably. The not too long ago retired Luke Rowe, who’s shifting to Decathlon AG2r La Mondiale as DS on January 1, 2025, says that he had issues concerning the strain being utilized on youthful riders by means of over-reliance on information. “I’m extra old fashioned,” he says. “You took racing critically however nonetheless had enjoyable. You’d go on a series gang to beast your self – and the competitors – to not hit sure numbers.”
It was a sentiment not too long ago echoed by former Olympic bike owner and Eurosport pundit Brian Smith on X when commenting about Steve Cummings leaving Ineos Grenadiers. “The psychological state of a rider is now being left in conjunction with the street due to the numbers recreation,” he wrote. “Altitude, haemoglobin testing… scientists appear to be the best way ahead. There is no such thing as a enjoyable in biking groups anymore. Science has killed this. Robotic riders and robotic sports activities administrators. Gone are the GRINTA days. Riders now know what they’ll obtain, what they’re up towards and switch up at races in a poor psychological well being state.”
Latré, too, who has a vested curiosity in AI succeeding, is pragmatic about its use. “AI has the potential to unlock marginal positive factors however it’s no silver bullet,” he says. “The professionals will nonetheless want coaches and sports activities scientists to work with. It’s one piece of the puzzle, not the entire half. The coaches additionally want to concentrate on messaging. If a rider’s information is low, it’d get within the rider’s head and performing badly might be a self-fulfilling prophecy.” In different phrases, the coach must calm and reassure the rider if they’ve occasional low days however, as they might now, act on developments.
All in all, AI’s means to analyse super quantities of knowledge at breakneck speeds could possibly be transformative on the subject of the velocity of the peloton. Aerodynamics which are totally dialled in, the proper race weight, tapered to perfection… the next-generation Pogačar could possibly be even sooner. However as Rowe and Smith caveat, what would be the psychological price of much more metrics to analyse and course of? If a rider actually does turn into a robotic, it’d equal extra velocity however extra enjoyable? Uncertain. We’ll end with one other AI development of 2024: time will inform…
