Rest Stops
There are 8 rest stops of the Mt. Tam Double Century, 6 rest stops on the 200K route, 4 rest stops on the 100-mile route and 3 rest stops on the 100K route providing restrooms, food and drink. In addition, a free feast will be provided at the end of the ride at Vallecito Elementary School.
 
The open times for all Rest Stops are based upon the potential for a rider to reach the rest stop if averaging 18 mph. If you are riding faster than 18 mph you may outrun a rest stop or two. If you are a fast rider and you start the Metric Century Course before 7 AM, you may reach Petaluma before it is ready for you.
 
For the Mt Tam Double Course only, the close is similarly based upon a rider reaching it based upon an 11.5 mph. If you are riding slower than 11.5 mph average, you may not make the Coleman Valley Loop Cutoff at Valley Ford. You will have the option to bailout onto the Century Course return. For the Mt Tam Double Century riders, any sagging or bailout options will result in a DNF.  There is a HARD Cut Off time for the DC riders of 10:30PM.  Anyone on course at that time will receive a DNF and be asked to be SAGed in.
 

Food
The Marin Cyclist Bike Club rides have earned a reputation for providing great food and lots of it. Exact selections and quantities will vary from year to year based upon availability and feedback from riders like you.
 
Most of the rest stops we will have peanut butter, jam, cream cheese, bagels, fruit, nuts, crackers, cookies, V-8, sodas, Gatorade, Cliff Bars, Cliff Gel etc. In addition there will be a surprise treat or two at some of the rest stops.
 
The Marin Cyclists will provide a free “after ride” meal for all riders (and volunteers) at the Finish. It will be all-you-can-eat-lasagna, pizza, Chicken BBQ (the chicken BBQ ends at 5 PM) and salad. There is also a wide variety of pasta salad, fruit and deserts available as well.
 
For the Mt Tam Double Century riders only, each rest stop will have Hammer Gel (bring your own flask) and Sustained Energy (SE) in addition to the normal fare. There will be an assortment of sandwiches available at the Valley Ford Rest Stop for the Double Century riders as well.
 
Restrooms
Restrooms or porta potties are available at all rest stops. In addition, there are restrooms at the top of Mt. Tam, at the Pan-toll Ranger Station (junction of Pan-toll rd. and Panoramic Hwy), Stinson Beach, Pt Reyes Station and Tomales.
 
SAG - "Support And Gear" or "Support Aid Group"
The Marin Cyclist club will have marked sag wagons patrolling the entire route. Each sag is equipped with tools and supplies to repair minor bike problems (flats, etc) and a broom to take care of roadside glass if such is reported to them. Riders are asked to report any glass to any sag or to the rest stop volunteers.
 
Use of personal sags in this event is prohibited. Any rider making use of personal sag will be disqualified from the ride and will never be allowed to register for the ride again. Personal sags increase the risks and dangers to other riders by increasing traffic and potentially making unpredictable turns or stops and create an unfair advantage reducing the challenge of the event. Consider having your potential sag volunteer to sag the course as a volunteer. This solution would add to every riders safety rather than detract from it.
 
Sag support is not the same as a taxi. We have had several riders try to direct sags to take them immediately back to the Start or forward on the course to “catch their friends”. Sorry friends. Our sags are on the course for everyone’s safety and the best we may be able to do is move you forward to the next rest stop where you will have to wait until another sag can move you one more rest stop (and on and on to the finish). We will make every effort to accommodate you.
 
Lights & Drop Bags (Mt Tam Double Century Only)
The Mt. Tam Double Century will begin at 5 AM in the dark and could, depending on your speed, potentially end in the dark. Sunrise is approximately 6:15 AM and sunset approximately 8:15 PM. Lights will be mandatory for the start of the Mt. Tam Double Century. The Marin Cyclist club will provide paper bags and magic markers for you to drop your lights at the first 2 rest stops. You can have the lights sagged forward to either the Petaluma Rest Stop or the Nicasio Rest Stop. Any bags not picked up, as the course closes, will be sagged to the finish.
 
You can also leave a drop bag at the start to be sagged to one of the last 2 rest stops.
 
Mechanical
The Marin Cyclist Bike Club works with several local bike shops to provide some mechanical support at the start/finish as well as at some of the rest stops. While this arrangement may not be able to fix serious issues, it should be able to resolve minor ones to allow you to potentially finish. If the mechanic recommends that your bike is not safe to continue on, we ask that you respect this recommendation and allow us to sag you to the finish.
 
Medical
The Marin Cyclist Club contracts with the American Red Cross to help support the ride. The Red Cross personnel will be at the Vallecito Elementary School and will also have substations at some rest stops. While everyone rides at their own risk, we try to do what we can to make your ride as safe and rewarding as we can. We are thankful that there has never been a serious injury in the 40+ years of this organized ride and we wish to keep it that way.
 
Communications & Radio
The Marin Cyclist Club works with the Marin Amateur Radio club to help support the ride. Despite our proximity to the major metropolitan area of San Francisco, much of the course lies in West Marin, which is still very rural. Cell phones are useless on much of the course. We work with this fine volunteer group of radio experts to link our rest stops and some sags to our base at the start/finish. This communication network is for the sole use of facilitating the administration of the event and emergencies.
