Today I set out on my my 6th Parkrun............and had to give up at 3k.
I started OK (ish) and kept thinking my breathing will settle soon, well it never did, I was huffing and puffing until I just couldn't run any more, I gave in and walked for a while, but just couldn't get going again.
There could be many reasons why this happened, like the cold air not agreeing with my lungs. Then again I set out too fast, I was fiddling with my Garmin 10 yesterday and had unwittingly set the virtual pacer to 5.45, so when my Garmin was beeping at me saying "on pace" or "behind pace" it kind of made me run faster (faster than I normally would).
Also I could be coming down with a bug (hope not) I can still feel that cold air feeling in my lungs over an hour later.
Oh well let's hope the tempature is a couple of degrees warmer next week, although I don't think that's gonna happen, I'm sure the forcast was colder for the coming week, roll on spring.
