Awesome. Just sent a request to join your FB group. I'm Brett.
Cool to hear you're from DSM originally. The Machine Shed is about 5 minutes from me, and I run in that area a great deal. I'm originally from Johnstown PA.
I'm with you contemplating the 50k solo. Could be do-able if I can get my butt in gear and train. ADV ride-and-run rally???
