this might be a repeat......

So, is it possible that my LTHR is close to 164? I do feel that when I’m in this range, I could go on longer, but I would really be suffering. I mean, I have been in the high 160’s and low 170’s, but it’s really hard. I haven’t done a field test yet to try and determine my avg HR for the last 20 min of a 30 min all out ride. I guess I could do that. I do know that my avg HR on most of my rides has been in/around 145.

I think for women, it’s 226-age, which would put MHR=185. I know I’ve seen 178, 183, 188, 195, and 197. I don’t think the HRM is wrong; I do think I have a higher heart rate. Or, could it be wrong?? I don’t think that a high HR means I’m less fit though. Anyway….I could get a LTHR test done for $85. Would this be better than trying to figure it out myself? I’m just getting so confused with all these numbers; Friel uses LTHR and others use MHR, so what do I use********************?? Damn, this is confusing.

Thanks for your help!
