From swimming to cycling to running, he’s made endurance his superpower – he even has the record for the most basketball free-throws in 24 hours. When he’s targeting a running record, like the 48-hour record he broke in 2025, Matthieu retreats to Kenya, where the altitude and simple life make for productive training. Known for his incredible mileage, Matthieu’s schedule often calls for back-to-back days of 100 km – precisely the kind of extreme training where the C1 excels.
