We've avoided this topic for 4.5 seasons, because it's (almost) as personal as your saddle choice...but we're waiting no longer. This episode is all about tire choice. Plus we get into the 9 miles between the base of Columbine and the singletrack turnoff. While you won't gain or lose a lot of altitude in this segment of the course, you're going to work for every mile -- and we'll help you know what you can do to power right through it!
