Thanks for the reply Scott. I think I glossed over the AnT test and just assumed that I was not suffering from aerobic deficiency since the bulk of my training before doing the AeT test was at a Zone 3 effort for me. I need to do both tests again and see where I’m at. You’re probably right, my spread is surely more than 10% between the two.
I am in week 15 of the 28 week 100k plan in Uphill Athlete. Would it be appropriate to introduce more Z2 and continue the plan?
