I haven’t ever managed to ride 100 miles in a single day, so the prospect of ticking off this little challenge with the support crews, burritos and ice cream that the Marin Century offers was not a prospect that I could turn down. While the Tour de Cure was significantly shorter, I argue it was actually the harder ride, with much steeper and more sustained climbing and a wider variety of terrain. Still, a lovely chance to blast up and down the coast and reconnoitre some new roads!
