So I'm on the list along with 59 others so far. Good mix of folks from all over the country.
The FAQ has been upated on the site in the last few days with more info. Note that you can get dispensation from the organizer to substitute a 400K fleche for a 400K brevet if you qualified as an SR or with previous 1200K experience. (I needed the dispensation due to scheduling issues; thank you, Matt!)
I definitely plan on checking out the Le Cirque du Cyclisme after the ride. That's very, very cool; thanks for the tip!
Getting excited for the ride!
