It takes 21 days to make a habit

I'm three weeks in to my half-marathon training program. 21 days.

Three weeks ago, I could barely run a mile.

Last night, I ran four. Four miles!

I feel like I'm making progress, but then remind myself. Four miles is less than 1/3 of a half-marthon...

Thank goodness I still have 12 more weeks to train.
