It sounds like you had a great time on your ride. And back to back centuries is an awesome accomplishment. Congrats!
But I think Veronica is talking about a 1-day double. When I looked at the
Solvang Double Century site it said it was a double century only, and the time limit was 15 hours.
While I've done back to back centuries, I've never attempted a double in one day.
Veronica, I'm in awe! Best wishes tomorrow... (And I'm in awe of Nanci too who has logged some amazing one-day mileage in her brevet series.)
