About
The NorCal Backyard Ultra returns October 22 and 23, 2027, for its 5th year on the trails around Folsom Lake. Every lap starts the same way. How many you run is up to you.
Two events make up the weekend. The Last Person Standing begins at 5:00 PM on Friday, October 22. Runners complete a 4.167 mile loop every hour, on the hour, until only one runner is left. The current course record is 35 yards and 145.8 miles, set in 2026. The Mini Last Person Standing starts at 7:00 AM on Saturday, October 23, and runs for up to 12 hours, so you can cover as many as 50 miles without running through the night.
Prize money returns: $400 to the Last Person Standing, $200 to the Assist, and $100 to the Last Female Standing. The Mini comes with a lower entry fee for runners who want the backyard experience and their own bed.
Whether you’re chasing distance, competition, or just curious how far you’ll get, the NorCal Backyard Ultra is a good place to find out.
At the start of each hour, runners begin a 4.16 mile lap and must finish it before the next hour begins. Failing to be at the start line when the next lap begins ends your race. The event continues until one runner completes a lap within the hour and no other runners remain.
The planned course will feature roughly equal parts road and smooth trail around Folsom Lake. Due to ongoing construction, the final route and elevation profile will be confirmed closer to race day.
Runners seeking the full backyard experience or goals such as 100K or 100 miles+ should register for the Last Person Standing event. Those looking for a contained challenge can join the 12 hour Mini event, which is limited to 50 miles.
The rules are simple. The challenge is not.
The "Mini"
If you want to experience the Last Person Standing format but prefer a more approachable distance, all within the daylight, then the Mini is for you. Designed for runners aiming for 12 to 50 miles, this event follows the same 4.2-mile loop every hour format but ends after 12 hours or 50 miles, whichever comes first.
The Mini starts on Saturday October 23rd at 7:00AM, with the same format and course as the Last Person Standing Event.
Equipment Rentals
If you're traveling to the race or don't already own equipment, you may rent a 6' table for $50 (taxes not included) or a 10'x10' tent, 6' table, & chair package for $140 (taxes not included)* from us. Rentals are first come first serve and will be available for pickup on race weekend. *Damage, lost, or stolen equipment may incur an additional fee.

Distance categories include 13 miles, 50 kilometers, 50 miles, 100 kilometers, and 100 miles. Runners who complete 100 miles or more will also receive a bronze finisher belt buckle.

Aid Stations
There are no "on course" aid stations but there will be a fully stocked aid stations at Beals Point for runners to use. Additionally, all runners will be given a parking spot near the start / finish line and may utilize the grassy area near the start line to serve as a personal aid station area.
Volunteering
Every race here only happens because volunteers show up to run it, aid stations, course marshals, packet pickup, all of it. Give one shift and you're not just helping runners finish, you're getting $120 credit toward any BLRC race for your trouble. Show up, hand out some water, make a few new friends, and walk away with credit toward your next start line.
Event's current local time: 5:38 AM PT
