The Marin Cyclists Bicycle Club is a group of bicycle enthusiasts who love to ride and in return gladly volunteer to roll out the red carpet for you. No one gets paid. We keep enough money in the bank to dig out if we lose some money on a ride but the rest is given away to select bike-related charities, sponsorships and concerns.
Ride overview for those NEW to the Marin Century
There are 6 ride options from which to choose. All 6 rides have some hills to climb but as long as you have done some training and are reasonably fit, there should be a challenge here for everyone. Please note however, that the Mt Tam Century and Mt Tam Double Century are technical, climbing centuries with long ascents and rapid descents and should only be attempted by competent, experienced riders. All rides start and finish at the same location, however since this is not a timed event, there will be no official "start time." There will be a initial start for the Double Century riders at 5am. With other rides going off from 6am - 9am. We encourage participants to gather and ride with old friends and new groups for added safety and fun. Please review the specific check-in times for your ride.
All the rides go through the best scenery in Marin. From the rolling hills, to Mt Tamalpias, to the Coast and back, there really is no better way to enjoy this part of Northern California than on this well supported, group ride. Each year we focus on putting on an enjoyable, safe ride. This year you can expect more CHP at major intersections aiding with traffic and bicycle safety. In addition we provide detailed course maps, well marked turns, and SAG/Safety vehicles for unexpected events. It is however the responsibility of the rider to have a well maintained bicycle, all necessary repair equipment including a pump, extra tubes, sunscreen, and enough power gel and water to make it between aid stations. Riding in a group is suggested, and helmets are always mandatory.
It is a requirement that riders obey all traffic laws. That means STOPPING at all stop signs and riding single file. CHP will ticket and has ticked before. Riders also need to watch speed limits. CHP has and will ticket riders for speeding. Also, iPODS or other MP3 or Radios if headphones are worn while cycling are extremely DANGEROUS and the rider may be cited by CHP! For your safety and the safety of others, don't use your iPod while riding!
Riders should complete the course between 12 noon and 10 pm, with most getting back from 1 pm-5 pm. At the finish of the ride there will be outside rinse-off showers available. Also, each rider will receive a fantastic lunch for which the Marin Century is well known. Last year's meal included BBQ Chicken, Pizza, Chipotle burritos, Salad, Fruit, cookies by Eat My Cookies, Haagen Daz ice cream, locally produced Gelato, drinks, and more. Friends and Family can purchase a meal ticket at the event. This is a festive, party atmosphere including music, videos and the Marin Century Bike Expo showcasing cycling related products and services, both local and national.
