Ok so firstly my 5k time sucks lol. I’m a female and am trying to go sub 22 on wed for my 5k PR in a time trial. Today I did a tempo at close to my race paces and let me tell you it was hell. My breathing is the same problem. I just breathe so hard that I feel it effects my overall running quality and think i’m not gonna break sub 22 especially since the tempo today was horrible. Ive been running 30-35 mpw as of now and have done intervals and tempo training (around 7:30 pace for tempos, and 6:45 pace for 400 m intervals with 400m jogs in between) Whats some ways I can better my breathing during 5ks and PR attempts?
