Just finished the couch to 5k - via the app. I looked at a few of the weeks to see what was in store and i really didnt think I would complete all the days , thankfully I pushed through them all. Did the 1st 6 weeks on the treadmill, and then the last lot outside ( all be it at night and in freezing temperatures) found running outside was a lot easier.
Didnt think i would acheive the end result as am over 22stone and didnt think joints etc would take it. I had some aches around my shins, so I spend 20 mins or so really stretching out the legs muscles, which really did help me through it.
Think the only advice I give and is to stretch those legs as much as possible pre and post run, i favoured this guy on youtube ( hope its allowed to post link)
Im moving on to 10k next week, giving myself the week off
