Fun for the first 6, ran out of energy on the 7th, slowed way down but was able to recover and continue on the 8th. Goal changed from winning to finishing : ) On the way down from the 8th both knees said we are done and there is not coming back from that unless you Advil the shit out of it and then suffer three months recovery from patella inflammation.
So seems like I reach both my fitness limit and my mechanical breaking limit.
Few more months of more hours on the feet hiking up and down and a bit less weight and the knees will not be a problem.
