Keys

May 15, 2027(projected)

Founded in 2008 by Bob Becker, Keys 100 runs point-to-point from Key Largo to Key West across 40+ bridges over 30 Florida Keys islands. The road-based course has negligible elevation and subtropical conditions; there are no official aid stations — runners depend entirely on personal crews leapfrogging at approved locations. The race is held each May and has produced 1,500+ 100-mile finishers since 2008. Men's record: Brett Sanborn, 13:20 (2019); women's: Alyson Venti, 14:42 (2014).
