After several false starts over the past couple of years, I started couch to 5k again this year on the treadmill, finishing week 6 last week. Previously I haven't got beyond week 2, shins, calves, general fitness meaning I couldn't go on. So despite it being extremely difficult, I've been delighted at my progress.
Feeling confident, today I decided to run outside for the first time. It was awful. I had to walk for 5 mins in the middle and was so slow it was embarrassing. I also got those shin and calf pains where it felt like I would have to give up. Not the usual tough "this hurts" but actual pain. I now feel totally deflated and feel like it's treadmill or nothing. I can't describe how hard it was.
I previously tried running outside and gave up each time. Really don't want to fail again.
