Classic TG Loop -- Tour des Suds to Moose Bones to TG to Link to Johns99 to Johns to 4:20 to Gravedigger
This is a classic epic loop ride on the south end of Park City. The ride as I've outlined it here is 13.6 miles with around 3000 vertical feet of climbing. Base altitude is 7350, top altitude is 8900 feet. Some navigation skill will be required, as there are a couple of spots where you can go wrong and get lost. Don't ride without a good current map, and it's very helpful to follow a GPS track file.

13.6 At parking

Getting there:
As you drive into Park City, you'll arrive at the "main" intersection of Park Avenue and Kearns Blvd. From the light, head south  on Park Avenue (straight ahead if you came from I-80, a left turn if you arrived on Kearns Blvd from US-40). Keep going through town. Just after the road veers a little to the right, it becomes narrower. As you reach the end of the homes and pavement, find parking on your left along the creek. Start the ride by continuing up the dirt road the direction you were driving.
