SF2G - Commute from San Francisco to Silicon Valley by Bicycle Skip the traffic. Skip the gym. Add awesome. Cycle to work from SF to all points on the Peninsula.

SF2G Preparation Suggestions


  • air: put at least 100 psi (road) or 60 psi (mtb/hybrid) into your tires, and you'll prevent most flats.
  • tires: if more than 4 years old, very difficult to remove/replace, or visibly haggard, replace them.
  • tubes: bring at least one extra, and make sure the size is right and the valve is long enough; also practice changing a tire at least once (how-to video). More info on how to fix a flat.
  • pump/CO2: bring a small pump or CO2 cartridge and suitable head/valve for it.
  • once-over: make sure your bike works ok and has reasonable lube on the chain, brakes don't rub, quick-release skewers are fairly tight, etc. If your bike makes sufficient noise during normal operation to obviate the need for a bell, you need to get it fixed.
  • seat: make sure the height is right, and consider buying a newer style saddle with anatomical design for your gender... and try it on a shorter ride first!
  • map: print out a map and throw it in your back pocket in case you get separated from the group. (maps on the group page, see link in nav.)
  • food & water: bring at least one water bottle and one source of calories (such as beer or a powerbar-like item).


  • fitness: be sure you can handle a 40 mile ride -- if you aren't very experienced, this will mean about 3 hours on a bike seat, so 20-30 mile practice rides are a good idea. try the Millbway variant of the Bayway ride before trying the full Monty -- it's about 20 miles and flat.
  • gear: invest in basic cycling wear, especially shorts with a chamois (padding). they don't just look good, they make your life much more comfortable (at least physically).
  • shoes/cleats: flat pedals are fine for around town, but you'll be happier on 40-mile rides with shoes that clip-in to your pedals. not mandatory, just advisable.
  • attitude: this is a fairly challenging ride if you're new to the sport, so bring a sunny disposition and patience, and you'll have a great time.


  • strava: The best way to remember how great the ride was is if you can record it. Sign up for an account on Strava and upload a track from your GPS or download the Android or iPhone app

that's about it! come out and try it! you'll dig it.
