Big Island International Marathon

Big Island International Marathon is a rolling marathon in Hilo, USA, held each March. Two out-and-backs from the Hilo Hawaiian Hotel along the old coast road. Most of the climbing is on the upper out-and-back toward Hamakua. The lower loop towards Richardson's Beach Park is close to flat. Hilo in March is warm, humid and often wet, typically 18 to 27°C at race time, and rain affected the 2026 race. With Big Island International Marathon's constant undulation, pace by effort rather than the watch: even effort beats even splits here.
