Hi

Decided to go back to my roots and concentrate for a while on L3/SST/L4 work to make sure I maintain and develop my core aerobic fitness. Had a very unpleasant surprise in that I found this really hard work and my HR was far higher than it was a while back for this session, it seems I have paid a high price for the higher intensity training I have been doing, the balanace has not been right. Measured blood lactate at the end of the 60 minute effort, it was 5.3mmol/l, miles too high for L3. Right, that's it, back to the science and the structure, no more HIT for spell until I get the basics back on track, I'm going to concentrate on FTP building.
