And That Makes Ten

1:17:51 workout time, Resistance Level 4, 15.16 miles, 11.68MPH avg speed, 807.8 Kcal burned, avg heart rate 165. One-leg training: Left leg, 40 revs, 192 peak heart rate, 14.3MPH (only saw one reading as machine cycles through all modes of display with each receiving equal time)

I spent twenty minutes in the 175-180 range with the rest being over 160 other than warmup for like three minutes where I was still 145+. I can handle the distance I went on a daily basis. I think I will standardize on 15 miles a day. A week ago, I wouldn't have thought it possible for another month.

I now have 127.35 miles behind me and I'm on track where I want to be. I started losing weight now, too. I've hovered between 212-213 with occasional peaks of 215, but I weighed in at 210 this morning.

I have new questions after today's workout and I need to get answers:

1. Based on the Fox and Haskell formula for training zones, I shouldn't be able to maintain a rate above 172 for more than a minute or so since that's my VO2 Max area. But I was doing it and did so for twenty minutes.

2. My peak heart rate is supposed to be 191 based on the Fox and Haskell formula. I saw 192, but I don't think that's my peak. I really don't want to look for my peak until my heart is ready for that kind of test, though. Is it possible that athletes just have higher heart rates from having more youthful hearts? Lance Armstrong maxes out at 201 or something like that, I remember.

3. If my heart rates really don't go along with the Fox and Haskell formulas, where are my real training zones? Does it matter? It would seem that optimizing at this point is kind of moot. Maybe I should just consistently train hard and leave it at that?
