I'm planning to do the Reston Century, metric version, which is on Sunday August 21 starting in Reston, VA.

On Saturday, Sept 10, I'm doing the Civil War (metric) Century out of Thurmont, MD.

(Note that registration is closed for this, so you if you're not already registered it's too late.)

On Sunday, Sept 11, I'll be helping out at the post-ride picnic for the Southern Maryland Century/Indian Head 100 in Indian Head, MD.

Will anyone else be participating in any of these rides?
