So after all my bellyaching and a good dose of sensible advice from the forum (as usual) I downloaded 'speed' and headed out during my lunch break.
I had had a yoghurt and a handful of dried friut for breakfast and was well hydrated. And a little nervous in the same way as i was when i first set off for w1r1 of c25k. I still think that that first run was my hardest ever and this was the same too - i was gasping and swearing and i had a stich and really wanted to just stop. Thank goodness its only 16mins! But i pushed through, inelegantly, i have to admit and its nice to have a new challenge.
I am assuming I will only get better at this so nice to know the worst is behind me!
