The Nemisis

I call this the 'Nemisis' because it's the hardest hill run that i can do from my house. It's about 5 1/2 miles with the 40% being a steadily increasing uphill, of course culminating in just a heart attack final quarter mile and then a gentle sloping back side all the way back down to my house. I'm still working on not walking at all. I'm down to walking about 20 meters just before the start of the real uphill (Mt Ribidioux) which is about 2 miles into the run. From mile 1.8 to about 2.5, you just feel like you are going to die as it quickly jumps to 5% all the way to 8% grade.
