Prosopis - don't give up on the HR. Maybe it takes months or years, but you can't "make" it happen. Be patient, and just keep training smart. Remember how far you've come over the last year or two!!!
I am 100% sold on the concept of racing (at least for tris) by HR more than pace and owe you a ton of thanks, Tri-Man, for all the postings on the topic here! I have been lurking and following the discussion. I used HR info to have a perfect day racing my 10-leg survival Tri a few weeks back and followed it up with a podium visit (in an Oly of all things) this past weekend. For just run training, I feel most comfortable at an HR between 163-167 (controlled breathing, muscles feel real good, etc). For the survival tri, my 3rd swim was at leg 7 and was a .7 mile swim (across a lake, with my shoes tucked in the back of my tri top). This scared the crap out of me, so my plan for the entire race up to that point, was to keep my HR below 160, with the thought that this would leave enough in the tank for this swim. Worked like a charm and I was then able to do the last 3 legs at a higher HR and actually ran the last 1.5 mile trail run on leg 10 at just over 9 MM.Used the same theory this weekend, with a bit of a different spin. I have been very weak on the bike this season due to a lack of training in comparison to last year. This has led me to lay back on the bike a bit. For Saturday's Oly, I used HR data to push myself late in the bike leg as I caught my HR dropping in to the 140s. Once I caught this, I picked up the pace and rode miles 19-24 all above 20 MPH, including mile 21 at 24.7 and mile 22 at 23.1. The target HR on the bike was 160, similar to the survival tri, to keep some fuel in the tank for the run. End result, was that my average HR was 157. For the 10K run, I used the HR info even more. My plan was to get through the first 5K keeping my HR under 170 and then just to go for it after that. Ended up with an average HR of 169 & a max of 179. Interesting, was that I was able to keep my HR around 165 for the first 5K and even ran the first mile in 7:48. I noticed, that my legs started to cramp as I pushed 170 BPM, which I hit on the nose at mile 3. Looking at the Garmin data, I only dropped below 170 once over the final 5K and maxed my HR as I crossed the line. My legs cramped a ton over the last 3-miles, but using the HR info over the entire race gave me the confidence to know I could run through them.Sorry for the infrequent posts. I have kept up here for the most part and lots of good things are going on!!! I wanted to share my take on racing by HR as I am seeing some pretty cool results and hope that this helps others.
