Sierra to Alum Rock downhill 2-3 loops - beginner 4.0m, climb 80ft, descent 1800ft.

I can lift up to 5 people (including myself) with bikes up (13 minutes carpool) and we'll ride bikes down. The plan is to shuttle up (13 minutes) with whatever cars we have and ride down (4.2mi) 2-3 times. Feel free to leave at any time. We will have to give a lift to everyone who's car is on upper parking lot when they leave. The trail is mostly single track, advanced beginner level.
