My girlfriend and I rode in our first and last Tour de Brooklyn. The pace was way beyond too slow. I've ridden in plenty of slow paced rides and enjoyed them, but the constant stopping was intollerable. TA should either have the streets closed for an appropriate period of time or not bother closing them at all (like the NYC Century Ride). Coasting for 10 minutes then stopping for 10 minutes is not a ride. We left the ride at Maria Hernandez and biked down to Manhattan Beach for the day.
I was especially looking forward to the Tour de Queens being a native to the oft-overlooked borough, but the TdeBklyn experience has given me serious reservations about it.
