Double Tour de France stage winner, the recently retired Irish pro rider Dan Martin was a climbing specialist. His racing weight was 62kg, which is light for his 5ft 9in height, but some shorter climbers weigh under 60kg. However, being super-light is no longer the preserve of the pure climbing specialists. Defending Tour champion Pogacar is the same height as Martin and only slightly heavier at around 66kg, while 2019 winner Egan Bernal, also 5ft 9in, is a true featherweight at just 60kg.
The riders mentioned start the Tour de France with body fat percentages well below 10 per cent, but nutritionists are careful not to allow ‘cutting’ to go too far.
In fact, it can be better to offload a little muscle, as Dr Rob Child, a performance biochemist who worked with several World Tour teams, explains: “It’s sometimes worth losing a bit of muscle to reduce weight because very low body fat has health implications. Tour de France performance is governed by the cardiovascular system, not by the maximum force applied to the pedals. Pro riders don’t need huge amounts of muscle to pedal at 400 watts for 20 or 30 minutes, and that’s often the key to performing well overall in the Tour. They need a highly developed cardiovascular system, not big muscles.”
