Jungfrau-Marathon

The Jungfrau-Marathon is a serious mountain trail race in Switzerland that demands respect for its terrain and elevation. You'll run 42.2 kilometers on trail with nearly 2000 meters of climbing, starting at 563 meters above sea level and topping out at 2319 meters, which means the course is relentlessly hilly throughout. This September event in the Interlaken region expects runners to have legitimate hill running fitness and trail experience since you're dealing with genuine alpine terrain, not rolling countryside. The race takes place entirely on trail surface, so expect loose footing, technical sections, and conditions that change with weather and seasonal ground cover. If you're looking for a fast marathon, this isn't it. If you want to test yourself against serious elevation and a beautiful but unforgiving alpine course, the Jungfrau-Marathon is worth training hard for.
