Shannon Hogan is a former pro mountain biker, ultrarunner, and open water swimmer based in the Cascade Mountains, Washington. She is the first female finisher of La Ruta de Los Conquistadores in Costa Rica (the world’s toughest mountain bike race), holds the women’s course record for the Pigtails 100K ultramarathon, and has successfully navigated multiple ridiculous-distance ultraruns including a buckle-finish at Leadville 100 and a sub-24-hour finish at the Javelina 100-mile run in the Sonoran Desert. Hogan has crewed every kind of endurance race on land and sea, including over eight hours of kayak support for an English Channel–qualifying swim. She has completed the Escape from Alcatraz swim, is a five-time finisher of the Ironman 140.6 triathlon and a seven-time finisher of Leadville Trail 100 bike race, and swims year-round in Puget Sound without a wetsuit as a member of the Notorious Alki Swimmers. She is old enough to know better, but young enough to do these things anyway. Hogan has written about cycling for The Colorado Sun, running for Ultrarunning magazine, and open water swimming for The Seattle Times.
