Above Timpanogos Park there is a great set of squiggly trails (obviously built by mountain bikers) that some call the racetrack. If you loop a specific route, it is exactly 2 miles around. Super fun. I have done it a few times now in the snow, mud, and dirt.

Go put it on your phone or watch and try to follow it! Great route.
