About the event

RACE INFO: We are so excited to celebrate the 40th annual Lake Chabot Trail Challenge Half Marathon and 5K. This race is well regarded amongst serious trail runners in the outlying areas. The race begins at 8am for the Half Marathon and 8:30am for the 5K. Please arrive early so that you may find parking, pick up your bibs, use restrooms facilities, and be properly prepared to race before the start. Race takes place rain or shine and there are no refunds.

RACE COURSE: The half marathon course is a scenic, hilly loop, mainly on dirt fire roads.  The ridge-line views look down upon scenic Lake Chabot, surrounding grassy slopes, and eucalyptus groves.  Mt. Diablo and San Francisco Bay are visible along the route. There are water stations with first aid and radio support; we recommend bringing your own hydration as well.  The half marathon has a time limit of 3.5 hours. The 5k (3.1 miles) course is an out and back that has gentle rolling hills and consists mostly of paved surfaces.  This route includes one water station with first aid and radio support.
