You gotta be kidding... World's Toughest Ultras

You gotta be kidding... World's Toughest Ultras

DNF % can be a bit apples and oranges when you consider some races have strict qualification standards, and if the entry fee alone is €3,100 for MDS, you're gonna be pretty motivated to finish!

The Barkley Marathon is obviously on a different planet for us mere mortals, but it was interesting to see the 9 Dragons Ultra 50/50 as the highest DNF race out there for the masochists who want a real challenge!

But it's a big world and we don't have all the answers. What Rambo tough races have we missed?? #T8run #trailrunning #ultrarunner
