5 mile aerobic test on the Nederland track at 8400ft elevation. Remember that I am not using MAF as my over-all focus for the marathon training at high altitude. I am basing this test (and all of them) off of marathon HR (AeT) and lactate threshold HR. My test is run at HR 140-150 which puts me a full 15-25 beats below my marathon HR and 27-37 beats below my lactate threshold HR.
Mile 1- 6:17 HR 144
Mile 2- 6:20 HR 146
Mile 3- 6:25 HR 148
Mile 4- 6:20 HR 150
Mile 5- 6:32 HR 148
Max HR did slip up to 154 at one point (I think Disturbed was on my Ipod). This was extremely easy jogging and I think this test is not indicative of my adaptation to altitude, rather it shows just how freaking hilly it is around here. The test was on a track but at 8400ft elevation and when I look back at my training logs for my past marathons- this puts me significantly fitter than I have ever been at 20 weeks before a marathon.

pm) 4 miles no watch no HR... just jogging.
