Our indoor cycling program gives you access to professionally-coached “spin” workouts that are tailored specifically for triathletes.  Our aim is to make you a better cyclist by focusing on strength, stamina and technique – but along the way you’ll have a lot of fun!


For classes at M2 Revolutions:


Street parking is generally available near the studio.  There is also a parking garage on Bush Street just after Polk. 


When you arrive to your first class, check in with the SF Tri rep, then head to the locker rooms where you can change and, after class, take a shower (bring your own shampoo and towel).  Gather on the rubber exercise mats until the previous class finishes and the participants have wiped down the bikes.  Then select your bike and get set up.  M2 will guide you through set up of the cycling computers.

Shoes/ what to bring

The spin bikes at M2 have pedals that take Shimano SPD cleats only. You are also recommended to bring: water bottle, towel to wipe sweat during class, towel/shampoo if you wish to shower after class.

Shoes/ what to bring

The cycle bikes at OMpower have pedals that take SPD cleats and cages for tennis shoes only. You are also recommended to bring: water bottle and large towel to wipe sweat during class.

IMPORTANT: Use of a heart rate monitor is highly recommended for this class. It will be the key way you will monitor your performance. If you don’t own a heart rate monitor and want recommendations, please email spin@sftriclub.org and we'll try to help.


All of our classes provide a great cycling workout that will build your strength and stamina to a noticeable degree during the 13-week session.  Shannon’s classes will focus a little more on technique and will also teach you how to use heart-rate to monitor your performance in training and in races.  M2’s classes focus a little more on power and strength and will use power monitoring.  In general, we direct folks new to triathlon to Shannon’s classes but experienced triathletes will gain much from either class.

If you want some help choosing which class is right for you, drop us an email at spin@sftriclub.org and let us know your level of experience with triathlon, cycling and spinning as well as your goals for the season.  We’ll be happy to provide more info and a recommendation.
