Another lactate test comparison and a massive well done to Sharon Colyer for managing to shift both her heartrate and lactate curves down and to the right. Basically meaning the same running speeds now require considerably less cardiovascular effort. LT1 has improved massively, and the fact that the line now stays flatter afterwards shows a much better ability to run progressively faster before lactate really takes off. This is the result of lots of easy Z1-2 running along with sub-threshold work after doing a short hill block.
Keep up the hard work, Sharon . I'm excited for the metric marathon and then next year's marathon goal π.
Thanks to Tom at Enduro Lab for giving us exciting days out and all the stats π.
