All races start and finish at Quarry Lakes Recreation Area.  The half marathon and 10K have large out-and-back sections on the Alameda Creek Trail.   The courses are mostly dirt/fire trail with a very small portion of pavement at the beginning and end.

Start Times




Half Marathon






The half marathon will start at 8:00 am and the course will have a time limit of 4 hours. Runners must reach the 5th aid station (mile 9.09) by 10:45 am.

For those who think they will need more time, we will offer a "Hiker Division" start at 7:00 am.  Those starting at 7:00 should carry water as the first and second aid stations might not be 100% up and running, depending on the hikers' speed.  Those choosing the Hiker Division start will not be eligible to win the race or receive age group awards, but will be listed as official finishers in the Hiker Division and will still receive finisher medals.
