If you're in the Mid-Hudson Valley this coming weekend, check out the Woodstock Century on Sunday Sept. 7th. It's a small well-run ride put on by the Mid Hudson Bicycle Club.
The ride features beautiful views of the lower Catskills, the Ashokan Resevoir & lots of rolling country roads. There are 37, 67 & 100 mile loops, along with a 6 mile family ride.
The ride is inexpensive as well. $25 walk in registration. Here's the link: http://www.midhudsonbicycle.org/?q=node/92
