RACE INFO: We are so excited to announce that we are back in-person for the 38th 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.

RACE FEE: Pre-registered runners will be guaranteed a t-shirt if registered by Sunday, May 9th, 2022.  The price for the 5K is $35 and Half Marathon $55. You must register by Saturday, June 4th. We will accept race day registration; however, the price for the 5K is $45 and Half Marathon $65. If you register on race day, we can only accept cash or check.
