Participation is free, and there are plenty of perks. We're hosting a group run where you can try out Mammut shoes.

When it comes to leading outdoor gear brands in Switzerland—a country blessed with breathtaking natural scenery—〈MAMMUT〉 is undoubtedly the first that comes to mind. Founded in 1862, the company has supported the adventures of countless mountaineers over the years. In recent years, 〈MAMMUT〉 has been focusing its efforts on trail running.

The collection features not only apparel such as T-shirts and shorts, but also a versatile 12L backpack and even three pairs of shoes with distinct styles—a lineup that clearly demonstrates the brand’s serious commitment to trail running.

Of particular note is the “Energy Trail Speed Low,” which is designed for short- to mid-distance runs—a trend that has gained traction in recent years. Weighing approximately 250g (UK 8.5), it is ultra-lightweight and features a TPU plate inside the midsole. Paired with a Vibram LightBase MegaGrip outsole, this shoe allows you to enjoy a light, nimble run with excellent foot mobility.

Energy Trail Speed Low ￥31,900

To experience its performance firsthand, a group run will be held that also serves as a test run for the “Energy Trail Speed Low.”

The event will be based at the office in Harajuku, Tokyo, and the route is expected to cover a distance of approximately 5 km around Yoyogi Park and the surrounding area. We are pleased to welcome athlete Naho Kotani as our instructor, who will share her expertise on trail running and highlight the appeal of products.

What’s more, in addition to receiving special commemorative gifts, participants can look forward to a social gathering featuring light refreshments and drinks after the run! And to top it all off, participation is free—which is truly amazing.
