The 50 Mile Epic ride is the centerpiece of the Santos Fat Tire Fest, as damned well it should be. Here's more or less a map of the route, shamelessly screen cap'd from here
General area orientation map, perhaps not 100% accurate. Out and back, but most of the trail was one-way traffic.
Favorite part? "Diggings" or some such name. I was riding pretty hard at the time so I didn't catch everything on the sign. It was a mile of short climbs that descended into scary-but-surprisingly-easy rocks and roots. Rolling fun! Least favorite part? The last five miles where my rear suspension had leaked down and my back needed a rest. I was forced – forced! – by the discomfort to stop for a coffee break. (freeze-dried crystals washed down with warm camelbak slosh, yum) Finished with a little bit of reserve in my tank, but pretty much ready for supper and a sleep.
Congrats to OMBA
(facebook link; sorry, all they got) for putting on another terrific fat tire fest. Already working on plans to attend next year.
