One of the toughest and most beautiful courses you’ll find anywhere! The Worlds End Ultramarathon is a challenging foot race following routes that are largely rugged, scenic-dense single-track trails with some fairly remote sections, several waterfalls and multiple vistas of the beautiful Endless Mountains.
The Black Forest Ultra 100k is a 65 mile lollipop style trail ultramarathon on 99% single-track/double-track. An elevation gain of 13,400 ft. You'll have 5 aid stations and a strict 19 hour cutoff. We think the Black Forest Ultra is equally, if not harder, than the Worlds End 100k and should be included as one of the toughest, most scenic trail 100k’s in the country too!
