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. 

This ride in the series takes us to Marshall via some spectacular scenery and a couple of notable hills. We leave Hal Brown Park and immediately climb Wolfe Grade, descend into San Rafael, cruise through China Camp, and stop for a Coffee at Peet’s in Northgate Mall. After the rest we will enjoy the exhilaration of a climb up Big Rock on Lucas Valley Road (photos at the top please). After the lovely gentle descent, we pass through Nicasio and make a stop at the Marin Cheese Factory before heading into the beautiful Marin countryside of Hicks Valley, and the Marshall Petaluma Rd. We climb the notorious (but really NOT that bad) Marshall Wall and drop down to the Shoreline Highway to views of spectacular Tamales Bay. After a brief and optional rest stop at the Marshall Store we head to Point Reyes for some ice cream or other yummy grub. We head home along the now familiar route of Samuel P. Taylor Park and Lagunitas, Fairfax, and back to Hal Brown Park. This is a challenging ride, and you are READY at this point!!

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
