Check out these guys:
www.cycleoutaouais.com . They have a MB club that rides at Fortune. Talk to Nicolas.
I'm more of a roadie. On my side, they only have Vélo Plaisir, a bunch of pot belly riders for the most part.
Then there is the Rouleurs de l'Outaouais, a top end team of racers but snub as hell. They won't return my emails and even Nicolas has sent a heads-up for me to one of the riders, but to no avail. OBC look like the only option for me next year.
I hear you on the "group ride" thing
