tommy said:Mark and Bill, how did you determine your race pace? Is it scientific, or art? Perceived effort? Heart rate? For some reason, by training book left that chapter out! Thanks.
Tom, my approach is homegrown. If it's consistent w/ any recommended guidelines, it's purely coincidence. But w/ that disclaimer:
I try to avoid shortness of breath while swimming, and breathe on every stroke. Swimming is easy for me - I used to be a successful competitive swimmer in my youth, so I still have my form, if not my engine. I always manage to land solidly in the mid-pack or higher w/o much effort. I always want to make sure I'm not out of breath before I jump on the bike.
I keep my HR about 140-150 on the bike in an Oly distance or shorter. That's vigorous riding for me, but I can sustain that for 25 miles without fading at the end. On a flat course on a calm day, that's a 17+ mph pace for me. If I spend too much time above 150, my HR gets too high on the run.
Running is my downfall. By the time I'm off the bike, running a 10 - 10+ minute pace raises my HR to about 160-165, and that translates to significant perceived effort for me. That's about 10 bpm higher than if I run a 10K that isn't preceded by swimming and biking. I can tolerate that for about 10K, and then I'm done. 170 is very uncomfortable for me (and also close to my theoretical max of 220-age). Yesterday, I was in the high 160's while barely moving. I decided to walk and let my HR drop, but I was only dropping to 150 while walking. I'd worry that there was something wrong with me if I hadn't had such a good 6 mile training run earlier in the week. I'll just write yesterday off as a bad day.
My post-surg resting HR has remained stubbornly high (78-80). Maybe that baseline has something to do with why I have trouble controlling my HR on the high end.
The bad day at the race is already paying benefits - I'm committed to a good training run first thing tomorrow morning!
