OK, I will try again.
Our annual bike rally has a choice of rides from 15-67 miles. You can also choose to attend just the dinner and speaker, too.
We are leading the 15 mile ride, as the others are rides we do all of the time. We ride to the start, on the Littleton/Harvard border, lead the ride, and ride home, so that is also an option for those of you who live close enough to do that.
All of these rides are hilly, including the 15 mile one we lead. There's a monster climb in the beginning , but after that, pretty flat, with rollers.
