The Vie'Athlon event, held at the Gentieg site near Janzé, offers an engaging multi-sport experience for all fitness levels. Participants can choose from various routes and activities designed to challenge both body and mind. For those looking to test their endurance on foot, there are three individual 5km and 10km runs available. The course has been updated this year to provide a more natural route through the woods and along quiet paths, ensuring an enjoyable experience for all runners. Prizes await the top male and female competitors in each distance. For families with younger children, shorter races of 600m, 1200m, and 1800m are also on offer. These runs provide a fun way to introduce kids to running while ensuring they have an enjoyable time. Medals await the winners, adding a festive touch to the event. Alternatively, those who wish to participate in multiple disciplines can sign up for Vie'Athlon, which includes swimming and cycling segments alongside their chosen 5km or 10km run. The swim takes place at the Ondines pool in Janzé, followed by a 25km bike ride under sunny skies. The event is part of France's broader goal to democratize sports participation through initiatives like the Prevention and Health (PPS) program managed by the French Athletics Federation. This means that adults only need complete a simple online health declaration rather than provide a medical certificate, making it easier for all participants to join in the fun. A warm-up area is set up before each run, providing runners with an opportunity to stretch and get ready for their race. The atmosphere at Vie'Athlon is lively and supportive, fostering camaraderie among competitors of all ages. The event benefits a noble cause: fighting cancer through donations that are split equally between the Institut Curie in Paris and the Eugène Marquis Centre in Rennes. Attendees can support this important mission by making contributions on site or online. With numerous family-friendly activities taking place throughout the weekend, Vie'Athlon offers something for everyone to enjoy. Whether you're a seasoned athlete or just starting your fitness journey, join us at Gentieg and experience an event that combines fun with purpose.
