Have you ever wondered what the toughest outdoor sport is? Outside magazine did and put that question to some experts to find out. The results might surprise you, but you’ll discover exactly which activities but the most demands on your body, and what some well known outdoor athletes consider the most grueling activities.
In terms of calories burned per hour, those sports ranked in ascending order as downhill mountain biking (632/hr), ultrarunning (768/hr), rock climbing (818/hr), nordic skiing (952/hr), and open water swimming (957/hr). This gives you a bit of an idea of how much energy you expend while doing each of these activities on a high level. It explains why these athletes are in such impressive shape too. Burning those levels of calories on an hourly basis is intense, particularly when done for an extended period of time. I can tell you that when I go on one of my longer runs (10-15 miles) on a weekend, I ended up being hungry the rest of the day.
So just which of these sports was deemed the most difficult? According to Outside nordic skiing takes the crown because it requires strength, stamina, speed, and a level of cardio performance too. Next up, was rock climbing in no small part because of the technical skills required, followed by open water swimming and downhill mountain biking. Ultrarunning came in last of the five sports listed, although everyone involved with the article admitted that it is still an incredibly tough and demanding sport too.
