• New for 2023: REFUND: Registered runners who drop prior to February 1 will receive a $108 (40%) refund. WAITLIST: Due to the very low number of registered runners dropping off the entrant list prior to March 15, we have emailed all the waitlisted runners that we’ll will be unable to offer more spots for this year’s race. We’d love to see you at the 2024 Miwok 100K!

• Join us as a volunteer for a really fun and rewarding day. Volunteers (8+ hours) will get priority registration for the 2024 Miwok 100K. Email info@miwok100k.com to sign up for a volunteer spot.

• We will again be offering our 18-week Training Plan. Following Coach Magda Boulet’s training plan will give you more tools to have a fun and successful spring racing season, even if you’re not running the Miwok 100K this year.

• The 2023 Miwok 100K is a WS100 2024 Qualifier, as well as a UTMB 2024 Index race at the 100K Level.
