This Event Took Place Sun. Sep 12, 2021


We are back for 2021 with a new date in September!

Want to run an epic trail race with amazing views?

Then check out your next favorite race!

Although our event was cancelled for 2020, the Excelsior Running Club is proud to be back to present the 3rd Annual Star City San Bruno Mountain Half Marathon! Sure to become one of the top trail half marathons in the country, the race boasts spectacular views of the Pacific, Bay and San Francisco. The race is 93% on trail, kicks in 2,400 ft of elevation fun, and has a screaming single track downhill section. We also offer a 5K Trail Race within the city of Brisbane.

The half marathon registration includes a t-shirt (if registered by 9/7/21), finishers medal, a pancake breakfast at Mission Blue Nursery! The 5K entry only includes a t-shirt (if registered by 9/7/21). Proceeds from both races help fund local community organizations!

Our race was dreamed up by runners who love the trails of San Bruno Mountain. We wanted to create an amazing running experience and then have participants enjoy breakfast while celebrating their accomplishment.

Start time

Our half marathon race starts at 8AM. The 5K race starts 15 minutes after at 8:15AM.

Cut-off time

Our cut-off time is 12PM (4 hours). Due to permit limitations for the park, we need to make sure that no runners are on the course after this time.

Aid stations

We have three aid stations for the half marathon run by volunteers at mile markers 3.2, 7.2, and 9.9. Each Aid Station will be well stocked with gels, water, and sport drinks. Note that WE ARE A CUPLESS RACE and recommend that every runner bring/carry their own water bottle.
