Bay Ridge Endurance Runs stand on the shoulders of giants. This race inherits the grand legacy of the Dick Collins Firetrails 50, following the classic 50 mile course and adds to it a new out-and-back marathon. We still run in Dick’s memory and continue the tradition of this classic race.

New in 2017, we are adding a 100k distance that will become the great new addition for ultrarunners looking to tip the scale towards the great 100 mile races in 2018.

The Courses

For those not familiar with Dick Collins Firetrails 50, the course is an out-and-back course; mostly along the legendary East Bay Skyline National Trail; fireroads and single-track with gorgeous views of San Francisco and Mt. Diablo. An altitude profile of 7,800ft makes this race challenging but very runnable. Three miles of pavement. Be prepared for any condition. Can be hot, perfect, or cold and raining. As was said of the race in years past, “previous years race week has included the following: fire, earthquake, flood, and stock market crash.”

The 100k uses the Dick Collins Firetrails course and adds to it an out-and-back along the Nimitz trail where you will have views into the San Pablo Bay. The course travels down the Conlon Trail to Alvarado staging area. The altitude profile for the 100k is just under 10,000 ft, meaning we should have a FAST race!

The new ‘L’Petit’ Marathon is an out-and-back from Lake Chabot to Skyline Gate, following a course popular to local runners and often run during our Epiphany Run fat ass each January.

Starting Time and Time Limits

The 100k starts at 5 am. The 50 mile starts at 6. The Marathon starts at 8. Time limits are:

100k = 17 hours
50 mile = 14 hours
Marathon = 12 hours

Cutoffs for the different races are firm because of our permits and the general curfew in the East Bay Regional Parks. Early starts are available for the 50 mile and Marathon. If you believe you need more time for the 100k, please contact us.

Schwag and Awards

100k runners have the chance to earn the Bay Ridge Rhino buckle along with shirt and our signature finisher wood-allions. 50 milers and marathoner receive shirts and wood-allions. Watch this space as we fill in additional give aways. Age Group awards are 3-deep for the 100k and 50miler and first place by group for the Marathon.

Aid Stations, Crew Access, Pacers…and Bathrooms

Complete detail on the location and spacing of the Aid Stations is to come ASAP but for information purposes, know that they are 3-4.5 miles apart. Crew has access to many of these stations. For the 50 mile and 100k pacers will be allowed from mile 31 (50mile) and 43 (100k).

For some reason, we’ve already gotten a lot of questions about bathrooms on course. Way to be prepared people. There are bathrooms irregularly through the course, at about miles 12, 15, 18, 21, etc. They’re out there, so no need to pack your Depends Ultra’s.

  • 100k

    The new 100k course follows the classic Dick Collins Firetrails course and add and out-and-back along the Nimitz Trail, then down Conlon Trail to Alvarado staging area. This will be a fast race that will challenge you with solid climbs, along with long stretches where you can really run.

    The altitude profile for the BRT 100k is just under 10,000 ft.

  • 50 Mile - in memory of Dick Collins

    The 50 mile course follows the same one that served as the Dick Collins Firetrails 50 for many, many years. You will start at the Cove Picnic Area at Lake Chabot and proceed out along the East Shore Trail and out along the ridges of the East Bay hills to the turn around at Lone Oak in Tilden Park.

    The altitude profile for the 50 mile race is 7,800 ft.

  • Marathon

    The 'L'Petite Dick' Marathon is an out-and-back race that heads out on West Shore Trail, through Bort Meadow and onto Skyline Gate. The race follows the same path back. This course has been popular in past Januaries (is that a word?) during the Epiphany Run. As has been true in past runnings of the Dick Collins Firetrails 50, marathon runners can expect to be passed by the front of the pack from the 50 mile and, maybe, 100k races. Root them on!

    The altitude profile for the Marathon is just under 4,000 ft.
