Margie Baer | Published on 1/1/2026
The 2026 Marin Century is now open for sign-ups. Don't miss this great event, now in it's 63rd year, staged at beautiful Stafford Lake Park in Novato, Marin County, CA on Saturday, August 1. The Early Bird Pricing is the same as last year. So lock in these low low rates before they are gone.
Choose from 5 routes, the 37 mile Geronimo, the 64 miles Metric Century, the 100 mile Century, the climbing 92 mile Mt. Tam, or the epic, mountainous 127 mile Double Metric. The courses are similar to last year, with a few improvements.
