So what? You rightly ask.
Well the LTHR is a point that when you perform above that point your body starts to accumulate too much lactic acid/lactate/H+ ions which, at SOME POINT, will cause you to stop.
But where is that ‘SOME POINT’. Well clearly for me based on that race it is AT LEAST 3.5kms (ie from 1.5km to 5km) and in fact I have stayed above it for 26 mins in a 10k and for 37 mins in a duathlon. In fact if you are fitter than me then you can keep at that level for over an hour…but probably not for a Half Marathon or a 2 hour duathlon/triathlon.
Going back to 5km then people can, apparently get their HR above that level for all but the first 30 secs or so. I’m not sure how though. As in my case to get my HR that high would require me to run a VERY fast first KM – which kind of goes against the idea of an equal split over all the 5ks of a 5k race to get a PB.
