My local hills where I do 90% of my training have some climbs that are just into my Z3 levels no matter how slow I run. When I walk these sections, I have a tough time staying in low Z2 and frequently am in Z1 (I seem to have a big hr gap between fast hike and slow run).
I’m entering my off-season and want to utilize the time to do some big aerobic base building and attack my ADS. Is spending short periods of time in Z3 detrimental or is the major concern that you might be too wiped to spend extra time in Z2? Trying to be exact with my cutoffs leads to some comical extended run 10 steps walk 10 steps sections. I’m not too proud to walk sections (walking is great) but I’d prefer to limit the transitions if I can.
In the past, I haven’t had an issue with recovery when I decided to run slowly during these sections but I want to be the most effective with my training time and if short periods of time in low Z3 cause a negative impact to improving my AeT, I’ll stop immediately.
Upcoming races: 50k, 50m, contemplating 100k
