I've changed my name to @Velocio now :)
I am interested... but won't know which dates I can do until about a month in advance of my doing it. My plan is to do this at some point this year, and to either buy or hire an MTB as needed. If timing is bad and I can't join a group I'll do it solo, my preference though is that I'd prefer to join a small group to do it (can be more fun, takes the risk off what to do in an emergency, i.e. accident).
For now, I'm just subscribed to this for updates.
