2023 Lake Chabot Trail Challenge

Lake Chabot
17404 Lake Chabot Rd

RACE UPDATE:  We were informed by the EBRPD that they had to close a few of the trails on our course due to the extreme storm damage we experienced this year. The bridge is also pretty unstable and have requested that we keep to the right side of the lake. That said, we have proposed an out and back with a few trail changes along the way for the half marathon course of which we received approval for. We are in the process of confirming the water stops once we survey the course for the best suitable location. The 5K course will be an out and back on the right side as well.

For safety reasons, EBRPD also asked that we have staggered starts. We will start 25 per heat with 2 minutes apart. I will ask that you seed yourself accordingly with the fastest athletes starting first.  We will still have the half marathon start at 8am and 5K to start at 8:30am. The 5K will also have a staggered start.

Updated course maps are at the bottom of the page. 

RACE INFO: We are so excited to announce that the half marathon course for the 39th annual Lake Chabot Trail Challenge Half Marathon and 5K has been designated as the 2023 RRCA California State Championship.  There will be special RRCA Championship awards given to top finishers.

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.
