Blandine L'Hirondel

Blandine L'Hirondel (; born 3 March 1991) is a French trail runner. She won the women's event at the 2019 Trail World Championships held in Miranda do Corvo, Portugal.

In that same year, she also won the bronze medal in her event at the 2019 World Long Distance Mountain Running Championships held in Villa La Angostura, Argentina.

In 2020, L'Hirondel won the women's race at the 2020 French Mountain Running Championships. In 2021 she won OCC at UTMB. In 2022 she won CCC at UTMB and the 2021 Trail World Championships held in November 2022 in Thailand.

In 2025 she won Diagonale des Fous, which takes place on the French island of Réunion. With a distance of 180 kilometers and around 10,200 meters of elevation gain.

In 2026 she won the UTMB in a time of 21:54:49, the first female athlete to complete the race in under 22 hours. This feat may have been made possible by multiple last-minute course changes, including one which was implemented after the race had started. It is therefore not yet clear whether her result will qualify for an official course record.
