I am entering Block III of LV Trad Base and that means Long Tempo work instead of Endurance (Pine Mountain, Moore and Diggins) these 2.5 hour workouts range from an IF of 0.66 to 0.71 TSS. Should I swap them out for endurance work instead? Perhaps Ptarmigan, Crows Nest and Gates (3 hours, ranging from 0.63 to 0.66 IF)?
Another thought on avoiding the middle Tempo and SS, when presented with a SS workout should I choose one of similar PL but higher IF? For example I have Carson -3 (3.1) scheduled for today, 1h, 65 TSS, 0.80 IF, 573kj, would Thunder (3.1) 1h, 65 TSS, 0.81 IF, 558kj be a better choice as it pushes closer to threshold?
Perhaps that isn’t enough of an IF difference to be meaningful but at a higher level would Tallac -4 0.82 IF be worth swapping in for Looking Glass -1 0.78 IF or is that still splitting hairs and a sweet spot workout is a sweet spot workout and there isn’t any benefit in messing with them.
