Don't know how I did it but I did, it wasnt pretty, it wasn't fast and it certainly wasn't easy! First 10 mins was ok, second 10 mins was soooooo hard. I took the same route as previous run so had these slight inclines. My main problem is how out of breath I get. I have tried concentrating on breathing but its just so difficult.
The main thing I will take from this is that it truly is a mental game, and I passed the mental part by not stopping even though it was very slow for the last two mins. Onwards to week 6!
I'm certain you are only moments away from conquering the breathing hang-up. I've experienced this too, and have panicked and worried about asthma etc. My chest got tight, my shoulders scrunched with stress etc etc. I took advice from fellow bloggers about keeping my breathing warm, eg wearing a buff...and waiting until the days are at their warmest before going out. This is difficult when you have a job and other commitments, but it can work! I too found Laura's breathing technique impossible. My main reason for saying earlier that I thought I'd found the 'zone' is that for the first time today, I completed the entire duration of the podcast and realised I hadn't thought about breathing once. This week certainly seems to have been as much a mind over matter thing, as an increasing run time thing. You'll get there - be assured. Give yourself a well deserved rest day or two, have a relaxing and happy Easter and breathe in the way that seems most natural to you (ie dont even think about it) when you start the W6 routines next week. Lots of luck x
