So, after about 5 attempts I can now definitely say that I have completed it properly. I was starting to think that I was never going to run for the full 25 minutes without stopping as I had numerous attempts with various results.
As half term was cropping up I decided to leave the running for just over a week and give my body a break (as well as my frustration levels). Today was my first day back running and I slightly tweaked my route so that I didn't meet my nemesis (the bus stop) before I was too tired as I always seem to think I can't go past without a break.
I managed to continue past it and was so proud of myself. No I can truly look to consolidate that 25 minutes in week 7, phew!
