Well I've been progressing through the weeks without too many problems and have been impressed that apart from a few niggles, I haven't felt achy the day after runs.
I did W8R1 yesterday and I feel like I've been hit by a bus (full of elephants, holding rucksacks filled with concrete). I just don't understand it, I don't think I went any faster. The terrain was a bit different as I'm getting further as I run more and I did jump some puddles and tree roots- but not with any gusto.
I am feeling a bit better after a walk and some foam rolling (OUCH) but will need an extra rest day. Any advice appreciated
