I've been really proud of my accomplishments so far in C25k - I've fought through every head rolling I'm too knackered for this moment but today I didn't make it. 17 mins out of 25, ran out of puff, dizzy and first bad stitch out of the 7 weeks. Walked, did another 2.5mins, walked again, and finished on the last 5 mins. I haven't quite figured out what went wrong, bar a head wind up a wee hill that really took it out of me this morning. I'll be having another go on Tuesday, but it puts doubt in me as to whether I should go back a week and try and improve before I have another go at week 7. I think I have hit my wall!
