Tom Donnenwirth earned his first pro victory on stage 1 of Tour de l'Ain, charging across the line in Lagnieu just ahead of David Gaudu for a Groupama-FDJ one-two punch. Andrea Vendrame (Decathlon AG2R La Mondiale) kept the French team from sweeping the podium by taking third place just ahead of Groupama's Lorenzo Germani.
After a day of multiple breakaways, a reduced peloton was back together in the final two kilometres, with four riders from Groupama-FDJ commanding the fast pace at the front. Rémy Rochas served as the lead-out for Donnenwirth, who sailed across the finish with both arms raised.
