Nope. We're really laid back. Find others in camp who want to do your difficulty level (ask at the registration tent if you don't know anyone on-site) and go enjoy yourselves. The private land trails on Friday and Saturday do require an ONSC leader but the URE forest trails do not.
I hope we get to meet you at URE!
Newbie here, trying to follow the FAQ. If I’m in an 80, is there organized trail runs, or would I be on my own?
John's answer to an earlier question is a very good summary for your consideration, but it is good to emphasize that you won't be on your own if you want to be with a group. The key is simple ... walk around and get to know a few people. This will lead to connections as groups come together with similar interests. And each day you will likely meet a few more people.
I have only attended a handful of Runs; so far, each year I make new connections with great people.
