Aid Stations

Aid stations will be stocked with water, Roctane Energy Drink, GU Gels, GU Liquid Energy, Coke, Ginger Ale, cookies, peanut M&Ms, PayDay candy bars, chips, peanut butter and jelly sandwiches, hummus/tortilla roll-ups, pretzels, pickles, salt, bananas and melon.

The Miwok 100K is a cup-less race, so you’ll need to bring your own cup for use at aid stations.

There is a portapotty at each Aid Station. We also provide MaskIt disposal pouches at each aid station for you to grab if you’re on your period and think you’ll need to make a pit-stop in the woods. Please carry the used pouch in your pack and throw it out at the next aid station.

Cutoffs

Review Aid Station Chart for cutoffs at each aid station and the finish; cutoffs are not linear.

15:30:00 – You have a total of 15 hours and 30 minutes to finish the race. Our Randall Trail and Bolinas Ridge cutoffs are very tight to comply with the California State Park permit that requires everyone off the course as dusk turns to dark.

Drop Bags

Drop bags will be transported to Tennessee Valley and Randall. On race morning place your bags – labeled with Bib # and Aid Station – where indicated on the SBCC front porch: TV, Randall, Finish. (TV bags are returned to finish by 2:30 p.m.; Randall bags are brought back to finish every two hours by crews. Finish bags are kept inside the SBCC.)

If it’s a cold morning, you can drop your jacket at the last minute before the start. We will place all Start Area clothing inside with the Finish Drop Bags.

Be sure to label your bags before arriving at the Start area. There will be no plastic bags or marking pens available. No daypacks or coolers can be transported. No valuables or breakables. 

Leftover drop bags are not mailed. Because of covid, we can no longer donate left-behind items. Drop bags not picked up race evening will be placed in the race dumpster at 9:30 p.m.

Crews

Crews are only allowed at: Tennessee Valley starting at 6:30 a.m., Muir Beach after 7:00 a.m. and  Randall Trail – all day.

Crew Driving Directions:

• Stinson Beach to Tennessee Valley Aid Station – SB to TV

• Stinson Beach to Muir Beach Aid Station – SB to MB

Pacers

Your Pacer must check in with the Aid Station Captain and sign a Pacer Waiver at the Randall Trail aid station before leaving with you.

Pacers must stay with their runner at all times, and can partake of food and drink at Bolinas Ridge aid station. Pacers may not mule, i.e. carry any of their runner’s gear, and must arrive at and leave the aid station with their runner. By leaving Randall with a pacer, you assume all responsibility for your pacer.
