By Invite Only

112 Miles of MTB
16,000+ elevation gain
2 days of riding


South of San Francisco, mountains rise between the bay and the ocean. Where there are mountains, there will also be trails. This ride explores these trails and connects a number of gorgeous public open spaces and parks that the Bay Area is fortunate to have within reach.

The ride has three distinct phases, which we will be tackling in two days. The first day will bring us down to the ocean and its cool marine layer, that, depending on the season, can blanket the coast for most of the day. We'll spend the second half of the day wandering through deep coastal redwood forest singletrack. We will hit famous Purisima and El Corte Madera (Skeggs) open space preserves, with towering redwoods basking in marine climate.

On the second day, after Skeggs, we will hit Bay Area Ridge Trail where we will take in the views of both the ocean and the bay – sometimes at the same time!  We'll then hit the John Nicolas redwood singletrack trail in Sanborn County park. The day will be finish with fire roads which we will hit in the mountains south of South San Jose. The fire roads are steep but the views will be rewarding. We'll end the trip by descending to Almaden valley and back to civilization.


This is a serious ride.  Designed to be done in 3-4 days, we will be knocking it out in two.  If you are interested in joining us, please contact me directly .

Once we have a final list of riders (limiting this to five), I will be coordinating travel logistics and sending out a proposed packing list.  Hope your summer legs are ready.

Teams will have 90 minutes to collect as many controls as they can find using only a map and compass.  Controls will have different values based upon their difficulty.  The team who collects the most amount of points within the 90 minute time limit will receive eternal glory as the one who rules them all.  Time penalty will apply for those who arrive after 90 minutes.

A great attitude

For those new to MTB navigation, it's a lot easier to read a map while riding when it is mounted on your handlebars (instead of in your pocket, in your sleeve, or under your sweaty hand.  While not required, you might consider the following map board options to make your life easier (and a little bit faster):
