With eucalyptus forests, grassy meadows, lakeside paths, and hill top vistas, Lake Chabot offers runners varied and stunning beauty. Our events at Lake Chabot are one of our more exposed courses, so bring sunscreen and perhaps wear a hat (an Inside Trail Headsweats hat would be a fine choice). Take advantage of our well stocked aid stations every 5-6 miles and be sure to thank the kind volunteers.

Parking at Lake Chabot Regional Park is free for all participants who arrive prior to the lots being full. There is additional free parking along the road just outside of the park. Carpooling is always strongly encouraged.
