I pushed the hills moderate hard this morning (max HR 171) and pushed the downs fairly hard. Pulled up at 6.5 miles in 46:11 (within sight of the FKT for sure but not possible today). Pretty fatigued from last weeks vertical which was the most I've ever run I think. The very long runs are also knocking me down pretty severely and I'm thinking that last week's 39 miler will be my last super long run before Leadville. I'll switch to faster, shorter long runs I think. The only way I'll run even OK at Leadville is if I unload fatigue and sharpen up, tough to do while living and training in these severe hills above 8000ft altitude. I'm fairly convinced that a 100 mile week up here is 'worth' 140+ on the flats at low elevations in terms of physical stress. If only because of delayed recovery. With delayed recovery does come increased training stress in subsequent sessions due to fatigue which can be reached at a much lower volume at high altitude. IE: you can run less and still get a big benefit.
So ya... I'm tired.
