am) 12 mile progression run. The last 3 miles were at marathon effort with out looking at my watch. 17:10 or 5:43 pace. Still too fast in regards to KC which is at ~800 feet altitude. Bob and I have been discussing whether or not you adjust pace due to altitude. 5:43 pace is exactly what I want to hold for the first 13 miles at KC... but because of altitude it won't be the same effort. If I did make the adjustment then my marathon effort at altitude would be ~5:53 pace or about 10 seconds per mile slower. Alan has told me that you don't adjust on relatively short efforts but longer ones you do.
pm) 8 miles- 50:01. Felt moderate/ easy.
