Third Annual Big Bloops Ultra
Inspired by BIG BACKYARD ULTRA | with support from BAYLOOPS.COM
Big Bloops Ultra is BACK for another round in 2023. The bloop will be closing in September 2023 for the Palo Alto Flood Basin Tide Gate Structure Replacement Project, so this will likely be our last opportunity for this event until 2027. Let's make the most of our remaining time with a whole lot of BLOOOOOOOOOOOOOOOOOOOOPS!
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.
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.
Parking is available at the Palo Alto Baylands Nature Preserve Trailhead, 2690 Terminal Blvd, Palo Alto, CA 94303. The bloop begins and ends just north of the trailhead at the pumphouse.
Bloops may be run in the clockwise or widdershins direction. Your score in the event will be the total number of bloops completed during the 24-hour period in either direction. Partial bloops will not be counted toward your score. You are permitted to leave the course and return during the 24-hour period if you choose.
The run begins on Friday evening. It continues through the night and the subsequent day, finishing on Saturday at 17:00. We recommend taking Sunday as a recovery day.
The run will happen rain or shine, and will NOT be canceled in the event of bad weather.

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. We do intend to provide one self-service aid station along the course, but recommend you plan to be self-sufficient and provide for your own nutrition and hydration.
Local time: 11:09 PM
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!
Attendees will be able to order an event T-shirt if they choose.
