Semi-Marathon et 10 km de la Vallée de l'Oust

On April 3, 2027, runners will gather in Malestroit for an exciting race day featuring both a semi-marathon and a 10km run. The course offers scenic routes along the canal of Nantes to Brest and through peaceful countryside trails. Participants start their journey with a brief exploration of the town's narrow streets before heading out on the flat, smooth paths that follow the waterway and continue onto the green route towards Roc-Saint-André.
The race day begins early for those competing in the semi-marathon at 2:30 PM, followed by the 10km run starting at 3:00 PM. To ensure a valid entry, all participants must present either a license or PPS card upon registration. Bib collection is available from 11:00 AM on race day.
Registration for licensed athletes opens on December 1st, with general entries becoming available to the public from December 8th. All finishers will receive a commemorative gift, and top male and female runners in both races will be awarded Tonton Outdoor gift certificates as prizes.
In addition to the main events, there's an exciting team challenge for mixed corporate teams and a fun run for children starting early afternoon. Race proceeds include a donation of €1 per entry to Roz’as des sables, supporting local community initiatives.
