comment Unusual heart rates and fitness
Your can't feel yourself if your training is aerobic or not, if your muscles are already trained enough. Muscle pain doesn't come from lactate, so there is no way except for, maybe, overall fatigue to determine that your training is off the aerobic limits. But the system long-term effects will show that. Sustained activity at as high heart rate as you report will most probably cause left ventricle hypertrophy (LVH), increasing risks of hypertrophic cardiomyopathies, which can lead into heart failure. So be careful and check you heart regularly for the signs of LVH.
