2018 course may revert back to 2015 and prior course. Current map and aid station chart references 2016 & 2017 course.
We will change this info once we get final word from the park on the dam project, and the final course plans.
50 mile race is 3 16.67 mile loops. All the same as each other.
50km race is two loops. The first loop is modified. The second loop is adjusted to the full 16.67 mile loop.
After everyone passes through the changed part (near the start of the event),
the course manager will change that section of trail, making it where you never have to know anything or watch for anything.
The course will magically look correct for you each loop without any thinking on your part.
