I'm not doing it this year, but TOSRV is so big that you never ride alone if you don't want to. (Or, often, even if you do want to.) Once you start, you'll find someone riding close to your pace, and if they look like someone you'd like to get to know, strike up a conversation! You can always ditch them at a snack stop or tell them you need to pee if it doesn't work out.
Have fun! Do you do any of the other COP rides?
