Karen Jarchow


Eagle, CO


Big things come in small packages. Karen is always striving to be on the top of the podium at the toughest marathons, as well as growing the youth of the sport through her kids mountain bike camp. In her rookie year, she proved to be the best, taking the 2016 National Ultra Endurance Series Marathon title and the 2017 Fat Bike World Champion. Whether she’s toeing the line or riding with the local youth, Karen can always be found with an unwavering smile.
