don't race based on your HR monitor. HR can change much for a number of reasons. Get in tune with your body and just go by how you feel during a short race. Don't limit yourself that way.

I believe that power based pacing, for example, is best for longer races to avoid working too hard early in the race and on the climbs. Personally speaking, for anything short I pretty much know how hard I can go without blowing up. But for longer races (Half IM, IM) it is often those short power surges that come very costly late in the race.

You can still use a HR monitor and look at your file afterwards but I wouldn't limit myself that way.

And as a side note, when you talk about your LTHR based on HR; you are using a variable (HR) to describe another situation (metabolic events at various intensities). While there is a correlation, it isn't perfect. Neither is it alwyas the same due to a number of reasons. HR depends on blood volume which is affected by your hydration status, HR changes with stimuli to the nervous system, etc. and it generally comes with a delayed response.

Yeah, I was going how I felt the whole race so that's not an issue.

Looking at it afterwards, though, I was surprised that the run HR was so low compared to estimated LT while the bike was kind of where one would expect.

I was just looking for outside thoughts on where that run HR should end up relative to LT, to determine whether I need to revisit how I'm estimating it, whether I truly am deficient at race pace run endurance, or whether this is typical.

usually the run HR is higher than the bike HR for the same exercise intensity. In a tri, since the run is at the end and your blood volume is most likely less than when you started due to some dehydration, your run HR should be even higher than during regular runs.

admit it that you didn't push yourself on that run.
