I'm going to ride 50 miles next weekend if anyone wants to come along. There's a great stretch of road by my house that rides next to a canal and there's zero traffic all day. You have a better chance of seeing a horse than a car. Anyway, I haven't ridden 50 miles yet (just did 40 today for the first time), so I'm assuming I should pace about 17 mph or so. So, if you want to come along, just post here and PM me.
