    Mt. Tam Dirt Fondo

    Anyone planning on doing it? 10, 20, 32 or 45 miles of dirt from Sausalito up Mt. Tam.

    Looks like fun:

    I have volunteered the last few years then ridden course after. It's a great time. They are also doing a second one on the summer solstice this year out of Woodacre. I can't make that one but should also be great.

    I will be out there for the Headlands version for sure. Check it out. Great cause, good people and a fun BBQ after.

    The description says it'll use Middle Green Gulch, but the map makes it look like the second-to-last climb is going to be up Coastal. Anyone know the truth to this? I'm seriously interested, but knowing that the Coastal climb is waiting towards the end would be a real demotivator.

    I've done the whole route in pieces before, but never the whole thing together. Looks like it's time to start training...

    In years pasat it has always climbed up green gulch then to the top of coastal and down miwok. I'm sure that is still the case. Plenty support out there too. Mechanical, food, etc. Do it!

    You are correct, goes up MGG, not the fire road.

    I did the 1st Tam Fondo in September 2012, it cost ~ $70. Fun day on the bike, PB&Js at the top of the Deer Park climb were awesome, but I can't imagine shelling out that kind of money (cost is almost $100 now!) to ride local trails and fire roads.

    Yes the route is fun/challenging and the support was decent but for a ride I could do any other day for free, I've never been able to convince myself it would be worth it to pay the cost of 2 new tires just to ride with a big group and have 3 aid stations....

    $100 buys a lot of pints of Casey Jones at Iron Springs!

    Sup IrieRider? Good to meet you at Tamo Classic. If you want to do Fondo for free, check out volunteering options. Work registration in the AM then go ride! It's less about the swag and more about supporting MCBC. Not a for profit ride like a lot of the other "fondos" around the Bay.

    Ah I didn't think of the volunteering option, that's a pretty good call and a more fun way to support MCBC.

    You going to be volunteering for helping with registration?

    Hope to see you out on the trails!

    I've got a training question. I just got back from a ride in the headlands (from SF to Coyote Ridge via conzelman/bobcat/old springs/coastal and back via Miwok/Marincello/Coastal). About 30 miles and 4,200 feet of total elevation gain, a little over 3 hours total moving time with a two minute rest stop at the top of coyote ridge. The ride wasn't the absolute maximum that I can do, but I definitely felt some impending cramps when passing tourists on the GG bridge on the way home. I think I could have added a Diaz Ridge (downhill) to Middle Green Gulch, but that would have been close to bonk territory.

    Does anyone have a training routine or recommendation for getting from here to being able to finish the 47 mile/7,000 foot loop? I've got a spin bike at home, can ride 1 or 2 times a weekend, and have a full light setup for night riding.

    That's a great question! We'll have a few training rides leading up to the September 7 Dirt Fondo, stay tuned. That said, if you eat and drink at every rest stop and pace yourself you should be able to avoid cramps. Stretching and pre-ride and post-ride prep are key too. You're question has inspired us to provide more information on training, thanks!

    If you do same loop but drop from Coastal down to Muir (on Coastal) and come back up Diaz ridge, cross shoreline to Miwok and Miwok back to Tenn Valley, you will get another 1,000ish feet. If you can do that a few times over the course of summer you will be golden.

    It sounds like you could do it right now with the support provided. Amazing how much propulsion comes from a crowd. Nice!

    PM if want any more route suggestions or Strava links. I ride from city all the time and have lots of Headlands/Tam combo routes.

    I'm good on the routes, just trying to figure out how to avoid the pesky simultaneous calf-hamstring-quad cramps when the climbing gets over 4,500 feet or so. Riding more seems like a good start.

    I am working on pushing my endurance also, with the goal of doing longer and longer dirt rides and a road century or two later this year, and pushing the cramping point farther and farther out.

    I find there is no substitute for time on the bike, and one good way to increase the time on the bike is to throw in a long road ride once every week or two. For me, road rides are usually easier on the joints but harder on the bigger muscles -- involving a steadier, lower-intensity effort that helps build base and core strength, and have helped me get to the point where 4-5 hours on the bike doesn't hurt. This is especially true when I pace myself. I often still start to cramp up in the calves at the end of a long ride if I have pushed it really hard, but when I focus on smoothness and efficiency of effort on a long ride (road rides are good training for that) it doesn't happen. Actually, the Miwok/Old Springs/Coastal-Coyote Ridge/Dias Ridge/Deer Park/Coastal/Middle Green Gulch/Miwok/Marincello/Bobcat route is like the mountain biking equivalent of a road ride, except all of the descents (aside from Bobcat) are of course much more fun.

    About 6 month ago I had more of a cramping issue after longer mileage, but much less so now.

    The other thing I have found that can help is steady nutrition and hydration, including before the ride, and using a drink mix while riding.
