Sob! Was doing so well till today....attempted Wk4 R1....got through the 3min run and short walk and then gave the 5min run a go...and failed!! My legs felt so tired and I felt so out of breath that I stopped after about 4minutes and almost cried!! All I wanted to do was jump off the treadmill and run home and hide in shame....But I was determined that I would finish the podcast so I power walked till I got my breath back, did the second 3 min run and was too chicken to attempt the second 5 min run in case I failed yet again! SOB!! I SOOOO wanted to do it...Feel like a miserable fat failure now..
