Leon is a French professional long distance triathlete and a Master of Chemical Engineering student.

In his debut year as a pro athlete in 2021, Leon moved up from 420th to 22nd in the PTO world rankings, thanks notably to a win at IRONMAN Mallorca and a 3rd place finish in what was his first crack at the full distance at IRONMAN Bolton in the UK.

Leon was introduced to Precision Fuel & Hydration by friend and fellow triathlete Mark Threlfall, just as PF&H were embarking on their fueling journey. Leon is quite a salty sweater, so uses a winning combo of PH 1500 and PF 30 in training and races.
