Join the 19th edition of the Mara-Trail de Marne et Gondoire, an adventure that combines sport and celebration as you traverse through the lush green landscapes across 20 welcoming communes. This year’s theme is "CARNIVAL," inviting participants to don their most imaginative costumes for a day filled with joy and community spirit. The course itself winds through picturesque countryside dotted with rolling hills and vibrant valleys, offering runners scenic vistas at every turn. Along the route, you’ll be greeted by enthusiastic locals, cheering crowds, and delightful food stops that cater to your energy needs while adding to the festive atmosphere. Whether running solo or as part of a relay team in the marathon (42.195 km), tackling the challenging 12-km trail race, participating in the leisurely nature walk or Nordic walking event, or taking part with children’s races tailored by age group, there is something for every level and interest. The day begins and concludes at the magnificent Park of Château de Rentilly. For this special occasion, the chateau grounds transform into a vibrant festival village complete with sports activities, live music, food stalls, and unique surprises guaranteed to delight visitors of all ages. A portion of each registration fee goes directly towards supporting animal welfare through the Foundation for Animal Assistance in Villevaudé. Experience the thrill of running amidst natural beauty while embracing the spirit of carnival fun at this beloved annual event.
