There's actually 3 pieces of single track now that I think about it.. it's very small and you'll be quite bored coming from those places. Tatum is good when you have limited time and want to get some miles in.. there's one hill and a few very small pieces of single track although 2 of them are fun. When I mean small, I mean one is less than a minute, the other is probably less than 2 minutes.. the third one is not worth mentioning though it turns into a little downhill to the double track leading into the main part.
