This “rally” included a mix of city riding, semi-rural roads, fire roads and single-track. The East Bay is very hilly and this was no exception. Steep hill climbs, bumpy downhill dirt descents, dirt climbs and whatever else can be thrown at you. Bike of choice is the one that you will have fun on and will get you through the course safely. A cross bike would do the trick, but so would a nice hardtail with skinny tires. Hell, even a road bike with fatty tires will suffice, although not recommended.
p.s. Watch the video full screen (unscaled) and with the sound/music on
