Pleased to report that I've just completed w5r3 (20 minutes running with no walking !!), and ........ dear I say this "enjoyed it". Laura it truely amazing she's absolutely right at this point it is mind over matter, your body can do it physically, it's all about training the mind.
5.2k in 37 minutes - well pleased. rewarding myself with an extra day off before parkrun on Saturday.
Tried to get money from ATM at the end of the run, I think my mind was still on running, had to put in PIN number 3 times before I got it right.
C25k really works everyone, keep at it and good luck.
