Its called The Gimbels Ride.
It starts at 9:20am sharp. Not a minute later.
Starts at the Cross County Shopping Center in Yonkers right off the highway.
The long ride goes North all the way up to Chappaqua. There and back is about 65 miles. This is a pretty fast paced ride where attacks will take place and where you will be forced to bridge gaps.
The shorter ride is about 25 miles and the middle ride is abot 40.
They obviously can't keep you from riding on public roads, but over 95% of the folks are roadies, so there are no aerobars. The other 5% are tri/du athletes who ride their road bikes. Maybe someone sneaks in with ITU-style bars but nobody rides cow horns, at least in the last three years I have known about the ride.
It's just not very smart to ride 5+ wide in a 100+ person pack on public roads open to traffic at 30mph. Remember, roads in NY are not like in Arizona - some of these potholes can swallow an SUV.
Let me know if you need more info or have any questions.
