Out again this morning at 430am to start week 5. Really thought I might struggle with the 3x 5minute runs but to be honest the first 2 went OK and near the last minute of the third I was puffing a bit more.
I can not seem to be able to breathe in through the nose and out the mouth. Its a mixture of nose and mouth to breathe in. Might get better with practice.
Recovery after each run seemed to be done well within the 3 minutes. Looking forward to he challenges of this week and next with the longer runs.
