Two great trail races in two beautiful places!
NO SPECTATORS, FAMILIES, FRIENDS, OR CREW AT THE 2021 DIRTY 30. Due to the ongoing COVID-19 restrictions, we do not have the capability of shuttling spectators to the start/finish area or the aid stations and unfortunately, there is not enough parking for spectators. Please respect this rule so this race can continue in future years.
