So I just finished a 2 hour hare and hound race where I wore my heart rate monitor. I did OK and had a lot of speed early on but just couldn't maintain it. Even after slowing down and resting I couldn't press for very long as I was just spent. After the race I looked at my heart rate results - 182 bpm average over the 2 hours with a max at 198 bpm. First of all, I'm 35 - is this bad for me to push this hard? (I'm going to ask my doctor at the next visit) Second, at this level I'm in the anearobic range and not getting enough oxygen which would explain why I can't seem to find that second wind. What type of training do I need to focus on to improve my heart rate during a race? I don't want to necessarily slow down rather improve my health and racing technique to keep it in control.
