Welcome to the Marin Marauder’s Progressive Spring Fling Sunday Rides. The Spring Fling Progressive rides are designed to get you ready for the epic BIG ride in June. We start off with smaller rides and build each week until you are riding over 100 miles a day and climbing like a pro. If you take part in this series you will most certainly be ready for ALC 2024. Not only are the rides epic, but the scenery and the people are too. We are a warm and welcoming group of cyclist of all ages and shapes. All AIDS/LifeCycle official training rides are an inclusive and safe space welcoming ANY and ALL, regardless of skill level or cycling pace. 

Alright! Since January we have worked up to this ride. The Century. All your hard work training will pay off today as we complete 101 miles with 5027 feet climbing. From Hal Brown we will head over to San Rafael and climb Lucas Valley to Big Rock (the hard direction) and have a stop at mule 19 at Rancho Nicasio. From there we will climb Cheese Factory and keep going into Petaluma for a food stop at Petaluma Market at mile 35. Once rested we will head out Bodega Ave to Valley Ford Road and take it all the way to Valley Ford where we will have another rest stop at mile 53. Backtracking slightly to Shoreline Highway we will do some climbing and then drop down into Tamales. Of course, as long as we are there, we might as well partake in Tamales Route One Bakery and Kitchen! We will then keep going on Shoreline Highway all the way to Pt. Reyes Station before heading back through Samuel P. Taylor Park. It will be a long day, but a very rewarding one.

The route is at:

All skill levels are welcome! If any ride is too much, we will work with you on making sure you have alternatives to the entire route. You will have a great bike ride. That’s a win! And remember, safety is critical. We will be following all bicycling laws and regulations as well as COVID regulations.!

Reach out with any of your questions or concerns. You really can do this.

If you are interested in attending, please RSVP so we have an idea of who’s coming. Have questions? Contact Ken and Temo at

REQUIRED ITEMS: bike, helmet, water bottle(s), tire changing tools, and a mask.

Parking: The rangers have politely asked us to NOT park directly in front of the park. Rather park further down Bon Air Road or on the opposite side of the street from the Park. By doing so, we will give greater access to the park by other patrons
