Rode the "woodchip" trail loop out there for the first time since this past Spring. I shattered my personal best by over thirty seconds. Did the entire lap in 9min 31sec... so that's over 14mph average for the entire 2.34 miles.
So the challenge is simply to do a lap and then see if you can beat your previous time. When I started out there I was in the 30 minute range... so don't be intimidated by my current time. Just go out there and do your best... it's really fun to see yourself go faster and faster over time.
