Trail Surprise
A trail run should be full of surprises, so why not branch out from the five established race routes and discover what other trail delights Grindelwald has to offer?

We have been bouncing around ideas for a race concept to include some of our favourite trail points, which are nearly forgotten nowadays and have created the ‘Trail Surprise’. The ‘Surprise’ element is that the altitude profile and the situation of the refreshment point will only be published 3 days before the race! Under the motto ‘A new surprise every year’ the trail length will be 10 to 15km with a height profile of 500 to 1000m and will also start and finish in the event area in Grindelwald. The trail surprise is held on the Friday of the event weekend.
Although the clock is ticking, the focus really is on fun and the shared experience along the beautiful and perhaps lesser-known trails around Grindelwald. The new race was conceived specifically with the relatives and supporters of runners in mind, as well as for trail fans from around the world. So the only thing you should be asking yourself is if you are ready for a trail surprise!
