About the race

The Call of the Wild event is the 2nd annual trail race held at Jack London State Historic Park in Glen Ellen, California. Races start and finish in the picnic area next to the London Cottage and follow trails through the historic Beauty Ranch on the slopes of Sonoma Mountain. The course passes the concrete silos and offers views of a vineyard before entering hillsides and meadows with madrone, Douglas fir, black oak, buckeye, and bigleaf maple. The route uses narrow singletrack in places and includes varied terrain on the ranch property. Distances offered: - Half marathon - 5.5 mile - 5K The course is marked with orange ribbon.

Aid stations are provided for the half marathon at miles 3 and 9.6, with an additional aid station around mile 2.5 for the 5.5 mile course. The half marathon has a 3.5 hour course cut off and hikers and walkers are welcome. Bib numbers are mailed beginning about two weeks before the event; mailed bibs do not require morning check in.

If a bib was not mailed, participants may pick one up at the start area on race morning. Event details include participant t shirts for all entrants, personalized award ribbons mailed to the top three male and female finishers in each age group for all distances, and finisher medals for half marathoners. Parking at Jack London State Park requires a $10 per vehicle fee and is limited; there is no parking along London Ranch Road.
