What part of Utah will you be visiting? What time of year? Is the purpose of the trip to ride all 4 days, or just a ride or two? Do you like technical, rocky, flowy, or jumpy trails? Shuttle rides, or lots of climbing? Where do you ride now?
Episode 21 (the one I'm currently editing) will focus the Whole Enchlada trail in Moab. Fantastic trail! I also love captain ahab, but it's VERY technical, and over the ability of most people.
