Jonas Abrahamsen is a Norwegian breakaway specialist for Uno-X Mobility. He became one of the faces of the 2024 Tour de France by leading both the points and mountains classifications in the opening stages, then won Stage 11 in Toulouse in 2025 after attacking from kilometre zero. His Roadman interview is valuable because it separates that verified race record from his first-person account of gaining roughly 18kg, developing more short-duration power and using high-volume, heat and altitude blocks. The individual physiology numbers are his account; the related published heat study reports group results and does not identify individual participants.
Official race and team records are separated from Abrahamsen's self-reported body-mass, power and physiology figures.

Jonas Abrahamsen is a Norwegian professional road cyclist for Uno-X Mobility. He is a breakaway specialist, won Stage 11 of the 2025 Tour de France and led both the points and mountains classifications during the opening stages of the 2024 Tour.
Abrahamsen won Stage 11 of the 2025 Tour de France in Toulouse on 16 July. The official Tour report records it as his first Grand Tour victory and Uno-X Mobility's first Tour stage win.
In his Roadman interview, Abrahamsen says he moved from roughly 60kg to 78kg and credits the change with better recovery and much higher short-duration power. The weights, power figures and causal interpretation are his self-reported experience.
The related five-week study in elite cyclists found a 42g increase in haemoglobin mass in the heat group versus 6g in control, but no statistically greater VO2-max or performance improvement. Abrahamsen reports his own VO2 max rose from roughly 70–74 to 84; the paper does not publish that individual result or identify participants by name.
The interview covers his 2025 Tour stage win, self-reported 18kg body-mass change, short-duration power, 20–35-hour winter weeks, heat and altitude work, controlled VO2 intervals and recovery from a broken collarbone before the Tour.

“My VO2 max went from around 70–74 to 84 in five weeks. That was pretty good.”
“If I had not gained around 20 kilos in 2020, I would never have reached the Tour de France. Becoming more explosive gave me the power to reach the key positions before cobbles, crosswinds and climbs with more energy left.”
“Before, I struggled to reach 650–700 watts for 30 seconds. Now I can do around 1,100 watts. My one-minute power went from around 600 watts to 850–900.”
