Course Map

Runners will run two (2) alternating loops, repeating for 5 times each loop, to reach the 50k mark. (See course map in photos.)
Runners will start on the 'Orange Loop': 4.45 Miles and then switch to the "Green Loop": 1.75 miles on the next loop. This alternation will repeat until 10 total loops have been completed. (5 Orange, 5 Green.)
Each loop is made up of: Buffed single track, some sand and we have thrown in some "fun" little hills.
This will give runners a mental as well as physical challenge!
