Hi everyone, my first post. Started before Christmas, due to mustle injury, holiday and all usual reasons, only on week 6 run 3 [3rd attempt this morning]. all other runs have gone ok. Started at 13st 10lb now at 12st 7lb [target 12st with the help of the Dukan diet, as prescribed by my GP]. I did the 20min run ok then when it got to the 25 minute I just can't get past 15-18 minutes. So this morning after about 12 minutes, I had to slow to a walk for 2-3 minutes, then ran again for about 8 minutes, walked for 2 - 3 minutes then ran again covering a measured [my local park run route] 5k in a total of approx 30 minutes. My thought is that I may be trying to run too fast as I have never run in my life, even avoiding it at school as I sufferd from Asthma till about 15 years ago. Also I stopped smoking about 3 years ago [30+ a day]. Does anyone else find the very cold air makes it much harder ? Really enjoy reading the blogs.
