Michelle Wharton (Hawaii, United States) biking in Marin

I had a great ride! Celia knew every inch of the trail and gave me a heads up of what was to come around every corner. At one crossing, she even got off her bike to block and wave me away from a dangerous drop. I will definitely ride with Mountain Biking Marin next time I'm in town.
