Make a left turn onto the blue-blazed trail and follow it a couple hundred yards to the Sanders Mound trail. Runners take a left

    and do a quick 1.1 mile out-and-back to the top of Sanders Mound. From there runners get back on the blue-blazed trail and head for the Lands End aid station.From Lands End, take the RED blazed trail for about 1 mile and then connect with the blue-blazed trail. Follow the BLUE trail and after crossing the Park road and it will turn into the white-blazed trail 3.5 miles from Lands End 1 at a point known as Cactus Ridge.The white-blazed trail will take runners to the West Park Road aid station. From there, leave the trails and follow the signs, flags and ribbons along West Park Road, staying on the grass, to Bunker Hill. This is the Goodwin Loop. Complete the 2.5-mile Goodwin Loop, which includes a traverse of Bunker Hill, and return to the West Park Road aid station. Runners then continue on the white-blazed trail back to the Lands End aid station.Leaving Lands End, continue on the white-blazed trail back to the Start/Finish aid station.

All vehicles must have this permit.+ Each time block will be capped at 50 runners.The Joy Hawk Addendum: Racers can run linked together during the event. We understand the joy of running every step of a race together with a friend, and that would be difficult to do if each person spins different loops. Friends who wish to run together for the entire race should check-in at packet pick-up at the same time and announce their desire to run the race linked. Rules for linked racers:+ Will spin the wheel as a team instead of individually. + Must run the entire race together. Loops run individually or without one linked team member will not count. + If a linked team places, they will share the award. If four or more linked teams are running within a time block, we will

    announce and recognize team rankings within that block. + Linked teams cannot exceed 5 racers. Event's current local time: 4:17 AM CT
