Happy 2025 UTMB week! To celebrate, Altra, Tailwind, and iRunFar have teamed up to offer three lucky winners a pair of Altra Experience Wild 2 trail running shoes and an assortment of Tailwind Nutrition products. Be sure to enter below!
This mountainous but fast race starts at 5:45 p.m. CEST on Friday, August 29, in Chamonix, France, and runners have until 4:30 p.m. on Sunday to complete the 174-kilometer (108 miles) mountainous loop encircling the famed Mont Blanc. More than 2,500 runners will set out through France, Italy, and Switzerland and gain more than 32,480 feet (9,900 meters) of elevation along the way.
You can bet iRunFar is here to bring the story of the race to you, wherever you are! Check out our in-depth women’s and men’s previews, watch our pre-race interviews with top entrants, and tune into our race-day liveblogging and social media coverage!

About the Altra Experience Wild 2 Trail Running Shoes
On the plush side for Altra, the Experience Wild 2 has a 4-millimeter drop and a rockered shape for a light and efficient gait during long runs on rough terrain. The trail shoes have a listed weight of 10.4 ounces for men and 8.8 ounces for women.
As part of the Experience line, this shoe has a compression-molded EVA foam for a light and responsive midsole. The rocker shape gives the feel of being pushed forward from toe-off without interfering with your natural stride. You’ll still find Altra’s roomy FootShape fit, so your toes have plenty of room to splay and adapt to the terrain.
Underfoot, the brand’s grippy MaxTrac outsole offers traction and durability over trails in varied conditions. These shoes make great hiking companions, too.
