I have had a few runs on the treadmill, so far no longer than a mile and a half. I’m still getting used to it, it’s very narrow! I seem to run much better/faster outside.
1/17: 1st treadmill run. 1 mile even, 13 minutes. 
1/18: 2nd treadmill run 1.5 miles in 19:50
1/20: 3rd TM run 1.7 miles in 20 minutes
1/22: 1.6 miles 19 minutes
1/24: 1.05 miles 12 minutes.
I’m getting better at making myself run on the treadmill and not messing with the speed. I need to watch something that keeps my attention so I don’t mess with the speed so much.
