About 90 percent bike paths but some traffic riding along Stinson Blvd and 15th Ave about halfway through. Make sure to have lights if conditions call for it. There is a nice climb on the north section of this loop, followed by a great downhill. This loop loosely follows part of the Grand Rounds loop but if you are coming from the west metro and don't have time for 50 miles, then try this one.by yekeraps
