Yeah, the trail itself isn't too difficult, there isn't any massive elevation gain, its mostly rolling, but there are a couple short tough climbs. Its all doubletrack, not hard at all to pass on. I'd suggest going with someone who knows the course (it is extremely easy to get lost, theres tons of routes) and seeing how hard you think one lap is. Beginner (And even about half of sport) is mostly weekend warriors, you should be fine. I'm racing sport this year as an independent, theres no rule that states you need to be on a team to go fast
Anyways, if you're looking for people who know the course and to ride with, post on UtahMountainBiking, theres a ton of people who will go. We went out there about a month and a half ago and had about 20 people show up.
