Courtney Dauwalter knocks two hours off Reunion Island 100-miler course record

Dauwalter is the first woman to have won Western States, Hardrock 100, UTMB, and Diagonale des Fous

Courtney Dauwalter Grand Raid Reunion 2022

Courtney Dauwalter has done it again. On Saturday, the athlete charged to an astounding new course record at Diagonale des Fous on Réunion Island. Diagonale des Fous, part of a group of races called Grand Raid Reunion, is a 164-kilometre traverse of Réunion Island that boasts 10,210 metres of elevation gain. Dauwalter ran to a remarkable finish in 24:37:47. The previous course record of 26:34:38 was held by the late Andrea Huser of Switzerland, who died as a result of a fall in the Alps in December 2020.

Réunion Island is a tiny French territory 800 kilometres off the coast of Madagascar, and has been touted as one of the most spectacular places in the world to race. The island is made up of tropical beaches lined with palm trees, stunning coral reefs and pristine blue lagoons, and is also a UNESCO World Heritage site.

Dauwalter was followed by France’s Anne-Lise Rousset in 28:58:52–four hours behind Dauwalter. Sweden’s Anna Carlsson finished in 30:59:18.

In the men’s race, Beñat Marmissolle of France left Switzerland’s Jean-Philippe Tschumi on the final descent, and finished in 23:14:47, with Tschumi close behind in 23:20:06.

In 2019, Canada’s Quebec Méga Trail (QMT) announced a major partnership with Diagonale des Fous, enabling all runners who finish the QMT 110K to register for Diagonale des Fous with automatic acceptance. The male and female winners are invited to participate in the Diagonale des Fous, all expenses paid (airfare and accommodation for one week), with the reverse also being true: participants in the Diagonale des Fous are able to register for the Québec Méga Trail without going through its contingency system.
