Overview
- Ben Dhiman won the men's Ultra‑Trail du Mont‑Blanc on Saturday in 18:16:29, the first sub‑19‑hour finish on this edition's course.
- Blandine L'Hirondel took charge from Lac Combal and finished the women's race in 21:54:49 despite a long‑running endofibrose iliaque and two late falls.
- Two former champions, Vincent Bouillard and Courtney Dauwalter, abandoned around kilometres 65–70 during the first night, which reshaped the leaders' battle.
- Dhiman seized the men's lead near Les Contamines (about 35 km) and ran largely solo, building margins of 30 minutes or more over his nearest rivals.
- Organisers confirmed the course was slightly shortened and winners receive €20,000 each, a sum publicly criticised by athletes who say payouts lag the event's commercial growth.
