      I agree with the others. This is a very flowy trail with fast downhills. Speeds above 20 mph are easily possible! This is a great section for beginners because of the lack of rocks. The climb is very steep in a few parts so expect beginners and some intermediate riders to walk their bikes in a few sections. Check out my youtube video if you want to see the full trail! It will skip automatically to the start of Nelson Loop: youtu.be/aVmrf4V97oc?t=355

      Excellent trail for the beginner to intermediate rider. Mostly easy climbing and great descent. Heads up: BoCo had all traffic going directional Clockwise on the day I rode, so keep your eyes peeled for a sign directing traffic at the top of Upper Bitterbrush where the park bench is.
