Sunday May 20th is The Sound Cyclists Blooming Metric 62.5 miles of riding with about ???? people.
Some CT Challenge Riders will use this as a training ride. CT Challenge riders are asked to use the CTC Jersey and meet at the CTC tent to ride out as a group. 
Visit the Sound cyclist for additional information on the ride..... It's a great Metric Century with just the right mix of flat riding, rolling hills, hill climbs, etc.  The ride is pretty well stocked at the rest areas and pretty well marked.  The Sag support in the past has been spectacular.  it costs about $50 & you need to sign up before the day of the ride.  no option to purchase at the day of the event.
