Join us for the 38th annual Lake Chabot Trail Challenge Half Marathon and 5K. on Sunday, 5 June 2022. 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. This race is well regarded amongst serious trail runners in the outlying areas.

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.
