I forgot to drink my morning coffee before I went out.
Never, ever again!
I ran/walked the first mile (after the warm up) in 13.53 minutes so not too bad but the second 10 minutes were brutal. My legs ached for the first time in weeks and I found it hard to breathe.
I'm half nervous about 6:3 but I'm not sure that running constantly is harder than stopping and then having to start again. I think, mentally, keeping going is easier.
I've also found that slowing down makes it harder both physically and mentally...I'm not fast by any means but if I go slower I find it hard to keep my feet lifting off the ground
