San Lorenzo River routes

This beautiful race takes place along the San Lorenzo river, a stretch of land that has the best that California has to offer, from the 300 foot redwoods to the quaint streams and every fern in between.

Terrain: The tracks follow an even mixture of single track and dirt roads.

Elevation Gain: This event involves a fair amount of climbing so runners should make sure they have included some hill climbs in their training schedule and warmed up those quads before they hit the track. The 10K offers an 800 foot climb throughout the full distance whilst the 50K route includes almost 5,175 feet of elevation gain through the race.
