Born in Cavaillon, Mathieu Blanchard grew up in Guadeloupe, where his parents ran a diving club. After training as an engineer he moved to Montreal in 2014, took up running and began winning ultra-trail races from 2017.
Known to the wider public after Koh-Lanta: Les 4 Terres in 2019, he finished third at the 2021 UTMB and second in 2022. In 2024 he won the Diagonale des Fous, his first victory at one of the major ultra-trail monuments. In 2025 he won the Yukon Arctic Ultra and finished second at the Hardrock 100.
He then turned to offshore racing: on 26 October 2025 he started the Transat Café L'Or on an IMOCA as co-skipper to Conrad Colman, reaching Fort-de-France in just over 19 days.
