Anyone want to weigh in on the 1 hr 45 min @ 184 BPM average? It seems that if I was able to do this, then my latest tested LT HR is too low. I am in better shape now than I was during the 1 hr 45 min effort, but I was better rested then.
Well, I can tell you that I have a _really_ hard time holding big heart rates inside, but no problem outside. I think cooling has a lot to do with it, but psychologically it's just completely different. I always test low indoors.
If I were you, I'd use a number of about 185 as a starting point and work from there. If you need to shift it up a beat or 2 during the season, then do so. I'd also try to do a 30 minute test outside when possible to get a better idea of the correct HR.
