Ride leaves from: Whipple Field
The original BRENTACOL climbing circuit. The bridge at Wilbur Road was out for a while, which is why I made the second version, which is probably a little harder. One hour solid effort. 50 minutes if you're faster than I am. The start location is listed as Whipple Field, which is located at the bottom of the final hill (Whipple), so if you park your car there you get to do Whipple an extra time.
