Running distance over time. I still can't run 5k without walking about 20% of the way.
And it's not going fast either, but I'm still proud of the progress. The data is keeping me going.
EDIT: Thanks for the support! The legs still don't want to do, what I want them to. But they will learn, who's the boss eventually.
Awesome to see progress charted like this. Years ago I decided to tackle a Couch to 5k program. At the start of it I genuinely could not run 2 minutes without being winded. After a few months, I was able to get first place in my age category in a very small charity run. It's silly, but I'm very proud of it. I stopped running a while back but I really should try to get back into it this spring.
