This is my first season specifically training for races & I've been reading the Friel book in conjunction with some great online info, mostly here on mtbr.com :thumbsup: After two months base training, I've finally got around to measuring my LTHR, using Friel's 30 min time trial method on an indoor trainer (not ideal, but my only option). So I find my LTHR is 190, which was about 15 beats higher than I thought it would be. My MHR is 199, and i'm a 35 yo. So looking at the Friel chart this morning I nearly choked on my rice crispies to see that the recommended HR zone 2 for my LSD is 157-168, or 79-84% of my MHR. I had been running my LSD rides at about 72%, Infact specifically avoiding the 80-85% range for two reasons- as I'd read several places that this is the "no mans land", and also as I rise through 82% I feel something funny happen in my body, which I think is a change in bloodpressure, it feels weird & I don't like it. I feel more comfortable from about 85% upwards.
At 191 beats, I'm toward the end of the Friel table. In mid table the zone 2 seems closer to 75%-80%. Should I go with Friel & increase my LSD ride zone or am I missing some crucial element here that's risking over-training?
