I've been running 30 minutes or occasionally 45 since late April and haven't really been able to tell if I'm making progress... I did notice that I didn't used to be able to run 30 minutes straight outside, and now I can, but I always seem the same amount fatigued at the end...

So, yesterday, for the first time in ages, I ran on the treadmill instead of the track or outside...

I was thrilled to find that I could easily run a 12 minute mile on the treadmill...

Last time I tried it, I could consistently handle 4.3mph and when I did three 8 minute intervals at 4.6 it was challenging.

So happy that I'm making progress!!!!

Nicely done!! It feels good to find measurable progress, doesn't it?

WTG! I am SO happy for you! Treadmill successes are fun NSV's

That's brilliant Uber, well done
I felt like I wasn't making much progress then last week had a brilliant run outside and have also started some intervals on the treadmill which aren't as hard as I expected. It's really great to actually feel and see it isn't it.
