How does an newbie rider examine to the demi-gods which are world-class street cyclists? It’s a query mulled over through many Sunday-morning membership runs everywhere in the global. A 2024 find out about didn’t essentially set out to respond to that query, nevertheless it did carry the physiological and function lid on a leisure rider who’d finished the 2023 Excursion de France parcours.
The 58-year-old finished the development in 191 hours in comparison to the WorldTour rider’s 87 hours, pushed through a VO2max just about part that of the pro and weighing 96kg in comparison to the full-time rider’s svelte 67kg. It makes for attention-grabbing studying, a minimum of from the perspective of who rode nearer to their particular person limits. However so far as seeing thru a comparative lens? They have been driving on a distinct planet.
Nevertheless it did get us considering, if a median newbie matched the learning hours of an elite and loved the full-time give a boost to of a nutritionist, energy & conditioning trainer, masseuse and game scientist, simply how shut may just an newbie come to blending with the sector’s highest? What separates the haves from the have-nots, the nice from the great? Naturally, that leads us to invite, what attributes make a super junior rider a super senior? Let’s dig into nature and nurture in our quest to achieve the highest of the Parisien podium…
Ageism regulations
Stephen Barrett is head trainer at Decathlon AG2R Los angeles Mondiale. He’s now not best concerned within the recruitment of riders to the crew’s WorldTour males’s squad but additionally its building and under-19 groups. He is aware of what it bodily, mentally and emotionally takes to achieve the higher echelons.
“Not surprisingly, the biggest factor that’d prevent someone making it at the top level is age,” he says. “It’s not something we should pat ourselves on the back for, but you become very ageist when it comes to recruitment. If you’ve got a 28-year-old or a 19-year-old, the probability of the 19-year-old developing to a higher level over the next four or five years is higher than someone who’s near 30.”
“That said, on our development team, that this year numbers 12 riders, we always try to keep spots available for late developers. Tom Donnewirth came to us as a 25-year-old in 2024 and made it to the WorldTour with Groupama-FDJ for 2025. Geoffrey Bouchard also came to us [as] a trainee pretty late, at around 25 years old. He’s still with us and has won King of the Mountains titles in the Vuelta a Espana [2019] and the Giro d’Italia [2021]. But all in all, most teams are ageist.”
Which arguably isn’t biased whilst you dig into the body structure. As you age, there’s a herbal aid in each the scale and choice of muscle fibres, particularly your type-2 fibres or your fast-twitchers that generate excessive ranges of motion for brief sessions of time. For plenty of, those lose energy at round 30 years outdated (albeit there’s little proof in Barrett’s crew, the 34-year-old Sam Bennett successful two of Decathlon’s 3 WorldTour victories up to now in 2025).

Conversely, type-1 fibres, the slow-twitch fibres, are full of mitochondria (the cells’ power manufacturers), a richer capillary provide and bigger cardio breathing for lengthy, stable efforts. Comparisons of muscle biopsies from more youthful and older people disclose that type-2 fibres are smaller within the older athlete, whilst the scale of type-1 fibres is way much less affected.
The explanation why is right down to many causes however the greatest perpetrator is a drop in testosterone, which reduces through round 1% each and every 12 months whilst you flip 30. That’s now not nice, as testosterone is essential for development and maintaining muscle, particularly the ones fast-twitchers. It additionally is helping to create pink blood cells, like nectar to the staying power athlete; boosts bone density to stop prerequisites like osteoporosis; and hurries up restoration between periods. Weight coaching has been proven to ameliorate this testosterone decline, however regardless of your dedication, you merely can’t generate the similar energy at 40 as you’ll at 20.
It is a an identical image with human expansion hormone. hGH is helping to burn fats and boosts muscle, however like testosterone, it drops as you age.
Ladies bear an identical age-related falls in muscular tissues (sarcopenia), which is heightened right through the menopause. Once more, energy coaching is helping, as does elevating protein consumption, however if in case you have ambitions of creating it at WorldTour degree for your overdue 40s, you wish to have to assume once more.
How effectively you could deal with 100km/hr descents of the Galibier or Stelvio continues to be observed, too, as analysis signifies that response time peaks at 24 after which declines through round 10 milliseconds a 12 months. That suggests a 34-year-old’s reactions may well be as much as 100 milliseconds slower than 10 years earlier, which may well be the adaptation between victory and defeat. Why? The decay is because of adjustments in nerve fibres that sluggish the rate of conduction as you age.
All concerning the genes?
In fact, there’s a genetic part to court cases. It’s possible you’ll possess the bodily and mental flair to coach as much as 30 hours every week, however do you have got the DNA? Are you a responder or non-responder on your coaching? Regardless of how arduous you take a look at, it’s now not assured. Take an early 2000s US find out about that checked out trainability, striking 742 sedentary folks on a 20-week workout programme. Measured elements integrated the power to procedure oxygen and resting pulse fee. Dr Claude Bouchard came upon that 10-15% of contributors merely didn’t reply to workout, whilst others confirmed a 40% development in how successfully their muscular tissues may just use oxygen.
“There are thousands of variations in our genes that influence endurance performance, which will be relevant to a road cyclist,” says Alun Williams, professor of game and workout genomics at Manchester Metropolitan College in England. “That much we know. What we don’t know is which ones. The proportion of genes we know too much about is very small.”
That applies the brakes to a just right leisure rider in search of out a sports activities genetic take a look at claiming to spot whether or not they’re naturally extra suited as an staying power or energy athlete. Years in the past, there used to be an explosion of a majority of these exams, advertising the dream of optimised coaching in accordance with your genetic makeup. I examined one myself from an organization referred to as DNA Have compatibility, which informed me one thing I already knew: I used to be extremely middling when it got here to energy and staying power. It used to be attention-grabbing, however basing all your exercising long term on effects from a handful of genes appeared slightly exaggerated, or as famous workout physiologist Graeme Shut would say about adapting Bonafide science for industrial alternative, “Sciencey.”
“Companies like DNA Fit went too early,” says Williams. “The vast majority of gene variants that should have been included weren’t, and do you know why? Because nobody yet knows what they are.”

Which isn’t to mention the likes of DNA Have compatibility didn’t have some substance to them. One gene lined through the take a look at that still become the focal point of David Epstein’s must-read The Sports activities Gene used to be the ACE gene. ACE stands for angiotensin-converting enzyme. It’s one of the most most-studied ‘sports’ genes, together with through Williams himself, and has been connected with staying power efficiency.
“There’s debate about whether if you have a certain allele combination, you’ll have naturally high parameters of aerobic fitness like VO2max. That’s still to be ascertained,” says Williams. You inherit one allele each and every out of your oldsters, with each and every pair of alleles representing the genotype of a selected gene. The phenotype is the observable expression of the genotype. “What seems clearer, or more probable, is that your ACE gene impacts how you respond when oxygen availability is low.
“Take a cyclist who’s constantly riding in excess of 2,000m above sea level. Their ability to tolerate and perform well at altitude could be affected by the ACE gene. In fact, it’s not just at altitude. Low oxygen availability is relevant deep within the muscle when working hard, so [it] is relevant at sea level, too.”
Do you have got the very best ACE gene aggregate that hoovers up oxygen regardless of the topography you’re driving? That fuels your running muscular tissues with an inexhaustible provide of staying power nectar? If you happen to do, that could be one step nearer to the professionals, albeit within the complicated global of genetic perfection, an excessively tiny step. It’s the similar with some other gene, ACTN3, which garnered an identical media consideration to the ACE gene round a decade in the past.
“It does a couple of things to skeletal muscle, including making a difference – again, a very small one – to the proportion of type-1 and type-2 slow- and fast-twitch muscle fibres you possess,” says Williams. “If your X allele dominates, you’ll naturally have slightly more type-1 fibres, which is useful for endurance. If you’ve got the other variant, the R allele, that’s going to give you slightly more type-2 fibres, so not as good for pure endurance but good for power.”
Select your oldsters correctly?
It is a complicated image on the lookout for your herbal propensity to rub shoulders with van Aert or Vollering on the top of the peloton however, in reductive style, is it merely about opting for your oldsters correctly? Reputedly, it didn’t do Mathieu van der Poel any hurt. His genetic lineage is well-publicised. His father, Adri, is a former six-time Dutch nationwide champion who received the International Cyclo-cross championships in 1996, plus has two Excursion de France level wins on his palmarès. Mathieu’s maternal grandfather is Raymound Poulidor, the eternally bridesmaid who three times completed runner-up on the Excursion and used to be 3rd 5 occasions. He did win the Vuelta a Espana in 1964.
So, Williams, in case your parents are aggressive street cyclists, are you much more likely to make it as a professional? “Maybe,” he replies. “Yes, their parents’ genes might be great for endurance cycling, but so might parents who’ve led a completely different lifestyle and didn’t cycle.
“I agree that if you have two people who follow the same training programme and one of them is clearly better than the other, then what are you left with? Genetics. But even then, we know through modelling work we’ve done that there are so many genetic variants, no one is going to possess the perfect endurance-athlete genome. It’d be like winning the lottery every week for a year. But to be a professional you don’t need genetic perfection – you’ve just got be in the top half-a-percent or so.” Some would recommend Tadej Pogačar is a Euro Hundreds of thousands victor day by day.
“Then, as it would be with an amateur athlete, it’s about maximising their personal environment – in other words, training, diet and lifestyle,” provides Williams. “The only way to really know if you’re good enough isn’t by having a sports genetic test. It’s to spend years training and living an athlete’s life.”

This brings us again to Barrett. The Irishman’s already dominated out nearly all of us from turning skilled because of age. So, let’s refine our seek to the more youthful cohort. What precisely are the likes of Decathlon AGR2R Los angeles Mondiale and their WorldTour contemporaries searching for in adolescent riders?
“We certainly look at their current key physiological attributes,” says Barrett. “One of the most important is VO2max. It’s a little crude, and if you’re a WorldTour rider and have a high VO2max but low efficiency [factors like low anerobic threshold and low FatMax], you’re going to be beat nine times out of 10.
“But when it comes to 16-, 17-, 18-year-olds, you need to make so many assumptions, one of which is that a high VO2max means they have the potential to tolerate the higher workloads that naturally come with training and racing at WorldTour level.”
Barrett says that the VO2max norm for the ones making the under-19 squad is a startling mid- to high-80s. That’s measured in millilitres of oxygen a rider can procedure each and every minute in step with kilogramme of body weight, or ml/min/kg, with a just right newbie rider tipping over 60.
As for tolerating workload, “On average, WorldTour men are racking up 30,000km a year via training and racing, though there’s a wide range there. Guys who are generally based in Belgium might reach up to 34,000km a year, with those in Andorra more like 26,000km due to the climbing metres.
“When you’re in your late teens, competing in junior races and cyclocross events, you’re looking at around 16,000 to 18,000km a year. That’s quite a discrepancy. You can’t just double that volume, but you do need to start closing the gap between the two levels to cope in races that regularly hit 240km. That’s one of the main goals of the development team – to help the transition from the under-19s to the seniors.
“Of course, there are outliers, like Paul Seixas, who this winter jumped straight from the under-19s to the WorldTour [via a glittering 2024 for the then 17-year-old that saw him win the junior time-trial world title and the multi-stage Giro della Lungiana]. But, in general, we gradually manage that progression to build durability.”
Beating fatigue… and the contest
“Durability.” That’s the sports activities science buzzword of the previous couple of years. In essence, it’s a rider’s skill to withstand fatigue over lengthy, brutal days within the saddle. Paintings through James Spragg, trainer at Tudor Professional Biking, confirmed that recent energy numbers between under-23s and senior riders have been just about the similar. What differed used to be the numbers they may generate when fatigued. Extra exactly, whilst under-23 riders’ figures dropped from as early as 1,000kJ paintings achieved, for senior domestiques, you have been taking a look at 2,500 to a few,000kJ. GC riders have been even upper.
Whilst there’s indisputably a genetic part to managing fatigue – as forementioned – Spragg famous that a large quantity of banked miles proved extra necessary to forging sturdiness than depth, albeit riders nonetheless had to handle a specific amount of high-intensity efforts.
“It’s why we’ve looked at durability, or fatigue resistance as I call it, for many years,” says Barrett. “Young riders and their coaches send us their data, but once we’ve shortlisted potentials, they undertake fitness tests with us, too. One involves a long ride that includes several five-minute efforts early on and again at the end to test their durability.
“Then again, I feel some teams are placing too much emphasis on durability as a key recruitment metric as it’s something that can improve a lot over two or three years, especially when they’re young. In fact, if a 17-year-old comes to us and has awesome durability and a large VO2max, you start asking yourself how close are they to their performance ceiling? How trainable are they are to improve over the next few years? You make so many assumptions when bringing young riders in, but that’s part of the job.”
Biking’s now not only a bodily combat, after all. There are the mental and emotional aspects, too. “It’s important that we identify some of the psychosocial factors that influence high performance,” says Barrett. “We’re keen to understand what motivates them and how they cope with pressure. The speeds have exploded at WorldTour level, and racing is more stressful than ever.
“We also look at the social media stuff but not overly. It’s not something we try to change or curtail, but we must be aware as coaches and directeur sportives of its influence. For instance, the younger riders might see Remco or Tadej riding 300 watts for six hours and try to do the same. They then might perform for a day or two but become inconsistent and blow up. We need them to have trust in what we’re doing with things like training plans and get them to buy into it. That gives them confidence, and hopefully they improve.”
Whether or not they support sufficient to make the senior grade continues to be observed. Whether or not you’re a budding skilled or a prepared newbie, you wish to have focus and a powerful pores and skin to withstand temptation and triumph over unhappiness on the lookout for your highest, no matter this is. Unfortunately, when you started studying this option considering you’ll have a good time your fortieth birthday through dressed in yellow, assume once more. Making it on the higher degree calls for taking this center of attention and making use of it at a tender age. For individuals who are studying this, overdue teenagers or early 20s, and are turning into disheartened that your professional dream will stay simply that, take convenience in our sign-off from Barrett.
“I use Ben O’Connor as an example to the younger riders of someone who didn’t break onto the scene like Tadej and Remco but grew into a world-class rider. He came to our team as a 25-year-old with potential. Now 29, he has second places at the Vuelta and Worlds (both 2024) to his name. Success isn’t guaranteed, but if you work hard, you give yourself your best shot.”
