That’s funny. I’m the exact opposite. I don’t feel overly stressed breathing wise during over-unders. It’s all my legs that feel in the edge of failure the whole time.
I don’t remember this being the case last year…BOTH legs and lungs were on the verge of failure the whole time. I think my extended base phase (TB 1,2,3, then SSB) has make things much easier respiration wise.
Legs still betray me though LOL. That said…I am hoping that all of this sweet spot and threshold work will quickly improve what I think is my main limiter right now…muscular endurance. Here’s hoping anyway…
…going to do Pasisade in an hour. I’ll report back and let you guys know if I’m still alive
