Running up a ski jump slope.
Ok, I do a bit of fitness, not as much as I should, but I try. Running wasn't really my thing but after I got into it and now I can't imagine not doing it. I would't want to compete with these guys, I don't even know if I'd complete the course! But I would love the chance to just try, I wonder if there is a ski jump slope anywhere in Spain (where I live) that I can go to. Anyway, while I'm googling ski jump slopes to run up, you can watch the action in this this video:
