This isn't really mountain bike specific, but I figured I'd post it anyway because she's just an all-around inspiring adventure athlete. Swedish-born climber, kayaker, and cyclist Renata Chlumska is only months away from completing her goal of being the first person to circumnavigate the continental United States via human power. Basically, that means hiking, biking, and kayaking around the perimeter of the U.S.
Ever since we interviewed her, I have a hard time finishing a ride after only 10 or 15 miles!
