Rendija Canyon lies just to the north of Los Alamos, in Santa Fe National Forest. We use three map areas and two start/finish locations, so please check the directions for the event. The map area covers mesa/canyon terrain at an elevation of around 7000'. The terrain is varied with sandy soil and rock, and many cliffs. The climate is generally quite warm and arid - runners are advised to use sunscreen and carry water - with the chance of flash floods in canyons if heavy rain occurs to the west (up to 10 miles, to the Jemez mountains).
