The trail starts in Lead on the new Homestake Trail, then down into Deadwood on the Mickelson Trail. Follow the Mickelson Trail up Kirk Canyon to the top of Sugarloaf. Take a left at the top of Sugarloaf, through the green gate. Follow the trail down to the Wasp Picnic Shelter back on the Mickelson on Whitewood Creek. Take a right, up the Mickelson. Stay low through the gate to Englewood Road. Follow Englewood Road, take a left up Snowcat. Snowcat Road is a long uphill with 7 switchbacks and turns into Snowy Bluffs Road. Take a left after the last switchback to the powerline corridor. Follow the trail under the powerline corridor to Railroad Grade Road. Railroad Grade is mostly downhill, ride back down to Englewood Road and take a left on Englewood Road. Follow Englewood Road and take a right at the Mickelson crossing back up Sugarloaf, past the top and back down to the Sugarloaf trailhead. Pass through the Sugarloaf Trailhead and cross the highway to Walt Green Park (Lead Trailhead of the Mickelson Trail). This ends the Mile High Course. Then coast down through Lead back to your vehicle.

 My garmin shows 1877’ of climbing and 1726’ of descending. Not sure how Trailforks came up with their numbers
