The 2024 Quicksilver Endurance Runs will be held on Saturday, May 11, 2024.

Updates:

4/14/2024: New for this year, pacers must sign a waiver, and receive a pacer bib before pacing their runner. This can be done at the Sports Basement bib pick up on Friday, or on race day at the Hacienda Start/Finish area or the McAbee aid station. Runners can pick up their pacer’s bib if they bring the pacer’s signed waiver. The waiver can be found here.
