Custer Area Chamber of Commerce recently issued the following announcement.
The 100 mile and 100 mile Relay will now start on Friday August 17 at 12:00 PM and the course will be open for 32 hours now. Then on Saturday August 18 the 50 mile will start on at 6:00 AM with the 30 mile starting at 8:00 AM and the 20 mile at 10:00 AM.
The reason for the changes is that the 100 mile races will continue to be an out and back race, but now the 50, 30 and 20 mile races will be point to point races. Same course but now an opportunity for more runners to see more of the beautiful Mickelson Trail during the event.
