The race

What this one is

Dick Collins Firetrails is an East Bay trail race with a 100k, a 50 mile and a marathon, held in September through the East Bay Regional Parks around Lake Chabot, Anthony Chabot and Tilden. It is named for Dick Collins, a founder of Bay Area ultrarunning. All three races are UTMB Index events and the 50 mile is part of the Pacific USATF Grand Prix. It is now part of the Bay Area 100 series.

Results go back to 1983. The guide calls it 43 years old. The race was not held in 2020. Ann Trason, a former race director, holds the women's course record.
