Big Bloops Ultra

Format

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.
The goal is to run as many bloops as you can within the 24-hour period, at any pace.
Some will try to break the most-bloops-in-one-activity record that is currently only 21.
Others prefer timed departures; for example, running one bloop every 72 minutes allows for a total of 20 bloops (100 miles). Join for as many or as few bloops as you like.

Course Description

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.

Support and Amenities

This is an unofficial, free, grassroots, fully self-supported event. We will collect and publish results, but there will be no bibs, no chip timing, no shirt, no awards, no finisher medals, no on-course photographer, and no whining. There is water available along the course, but recommend you plan to be self-sufficient and provide for your own nutrition and hydration.

If you intend to participate (even for just part of the event), please register through UltraSignup in advance. There is no entry fee. To comply with park policies, the event is capped at 24 entries, making it even more exclusive than Western States, so get your registration in early!
