I’ve been using SUFF for a few months now and love it.
Last night I ventured into the real world and did 1 mile interval laps of a motorcycle track (so flat and pothole free and safe!).
Legs were strong and never caused me to want to quit (I was using all the tricks from The Bat too) but by the end of my fast lap I sounded like a steam train my breathing was so hard. HR wasn’t massively elevated but breathing was shocking!
What element of training/videos do I need to do to reduce this so my breathing is as strong as my legs.
