This is a 24-hour timed event. It does not share the "last person standing" format of its namesake; instead it is designed to encourage participation throughout the event from runners of all abilities. You have the option to take part in one of two formats:
- 24-HOUR BLOOPATHON - Flexible schedule. Run as many bloops as you can within the 24-hour period, at any pace.
- BLOOPING LIKE CLOCKWORK - Timed departures. One bloop will begin every 72 minutes, for a total of 20 bloops (100 miles). Join for as many or as few as you like.
Enjoy the beauty of the San Francisco Bay on the BLOOP. Officially known as the Adobe Creek Loop Trail, the bloop is a scenic 5-mile (8km) loop meandering around Adobe Creek, Charleston Slough, Matadero Creek, and the Mayfield Slough. It consists of 1 mile of pavement and 4 miles of smooth dirt, and is extremely flat, with less than 20ft of elevation gain and loss per loop. It provides opportunities to see a wide variety of waterfowl, including pelicans, egrets, herons, Canada geese, seagulls, and ducks.
