Run two races in one. The Straight Up Kilometer to the top of the climb and the 10k which is from the bottom to the top and back down the other side! The prize money is for the SU K only. You can run the Straight Up K and then just walk down the other side. You don't have to race both but we will give you a time for both. Runners take on a 2.8 mile climb that goes from 2,900 ft up to 6,200 ft! You will be on all 4 fours and climbing what is without a doubt one of the hardest trails in the world! Unlike other SUK events, you will have to run down the other side from the top. This is a two races in one race! We call it the world's hardest 10k for how crazy it is.
