Back in Nov. 2015 I was in this thread logging some running drills I was doing, then I encountered a calf injury I'd never had before and it killed that motivation. A year went by, I then did a few short runs in Oct. 2016 but wasn't really into it. Then my gf insisted I support her in running 10k around our town. So I reluctantly agreed and end of Nov. 2016 we ran a casual 10k, but the last 3k my legs were gone. It took us 1hr 8mins. Afterwards I felt rough for days - how much was due to the run, and how much due to some bug or something, IDK, but I then didn't run again until March 2017. Reason I started again was to support gf as she started entering us in local 10k events - yay! So we did our first organised 10k at the start of April, but in the last kilometre my knee started giving up and I had to walk for about 700m. My time was 1hr 5mins. But then I went out for 5 more runs in April, of varying distance, before yesterday we did our 2nd 10k event. My time was 58mins, so things are going in the right direction. I've now got a couple of months before my next event, so I'm hoping for some injury/illness free time to keep up the momentum. I ran a 10k ten years ago in 53mins, so that's my next target, but I'm pretty sure it's easier when you're 26 than when you're 36.
