Race Entry Summary
RunThrough Interlaken Trails Festival
- RunThrough UK June 2025
We are excited to introduce to you our Brand New RT Trails Event RunThrough Trails Interlaken
42k, 22k & Up & Down Race on 15th June 2025
The races are unique challenges taking runners over the Aare River that joins Lake Thun to Lake Brienz then up vertically into the terrain around the Harderkulm, a stunning viewpoint offering breathtaking panoramic views of the surrounding landscapes, including the Eiger, Mönch, and Jungfrau mountains, as well as both Lakes. The running is technical and engaged with some faster sections on the descents. The 42K route sees the 22 K extend into the gorgeous rolling valley of the Beatenberg area, where you’ll run alongside Lake Thun and through mountainous river gorges.

We have been extensively researching into what runners consider important, and sustainability is fast becoming the most important area. Click HERE to see what RunThrough is doing for sustainability.
T-Shirts at events have been a hot topic mainly around them not being a high enough quality to wear on a regular basis. So we have decided to tackle this by offering a T-Shirt (Women – CLICK HERE | Men – CLICK HERE) with a retail value of £22 for £12 with the addition of the event logo printed on the chest. These are to be collected at the Kit Stall on the day.
We can do this with our partner RT Kit as part of a strategic decision to raise awareness about the quality of the product whilst reducing the overall cost of events for those who would prefer not to have this included.
