Blimey, that was a struggle, not sure why. That's the closest I've come to giving up and walking a bit, but I kept running - well, 'running' is a huge overstatement but I kept my 'light jog' as Laura puts it, and just about managed the 25 minutes.
I think I might be getting a bit cross with myself for going so slowly, thinking that because Laura says I'm a runner now (!) I should be going faster - so I might subconsciously be pushing myself to go faster then puffing myself out. Which is so counter productive, when I think about it.
Please remind me that even at this stage it's OK for me to be going slower than I could walk, as long as I'm jogging?
