This is a short video montage (2.4 minutes, 44.4 MB) I put together from a big group ride in Skeggs (El Corte de Madera) with the South Bay Mountain Bike Group (via Meetup.com):

I created a time-lapse recording of riding the Saratoga Gap to Long Ridge loop in Santa Clara County.  So that’s a 90 minute ride condensed to 3 minutes:

Admittedly it’s pretty hard to follow along while in the trees, but it looks pretty cool at about the one third point where the trail opens up.  I’ll have to try this again sometime on a trail that has much more open riding.
