 snowing, extreme snow, weather, how your body is going to acclimate to different things throughout the race. So let's talk a little bit more, Rachel, about what is the Arrowhead 135? Sure. Well, as you mentioned earlier, it's a 135-mile run. It's from International Falls, starts out on a snowmobile trail, and follows the same snowmobile trail all the way to a casino near Tower, Minnesota. So really beautiful section, but not like paved footing at all.
