Volunteer, Driving Directions


The Miwok 100K could not take place without many wonderful volunteers who mark the course, work at the aid stations and the start/finish, and help remove the ribbons and clean up afterwards.

If you’d like to be indispensable (and have a lot of fun without running all that way), email Volunteer Coordinator Magda Boulet, at magda@miwok100k.com or RD Tia Bodington, at miwok100k@gmail.com with the specific spot you want (see below), or tell us when you’re available and we’ll place you at the perfect location.

Volunteers (8 hours+) receive an early registration option for the 2024 Miwok 100K.

2023 Volunteer Opportunities:

  • Friday, 5/5 – Mark a section of the course.
  • Saturday, 5/6– Staff an aid station:
    •  Start: 3:30 a.m. – 8:00 a.m.
    •  Finish: 12 Noon – 9:30 p.m.
    •  Muir Beach: 5:45 a.m. – 1:00 p.m.
    •  Tennessee Valley: 6:15 a.m. – Noon
    •  Randall: 10:00 a.m. – 6:00 p.m.
  • Saturday, 5/6 – Sweep a section of the course; 10-15 miles, close behind the last runner.

If you’re running the race, consider asking a friend or two to come along as volunteers. You’ll all have fun, and you won’t have to drive yourself all the way home after running 62 miles!
