I broke myself of the treadmill habit after
- new treadmills were installed in the gym (with a more honest speed and incline calibration)
- beginning carpooling (arriving @ 5:30 to 6:00am is not feasible for everyone)
With the new treadmills on 1%, I built some solid strength. Other benefits that I missed:
- Softer landing surface
- Consistent pacing -- easier at beginning, but harder at end.
- Controlled pacing -- I was running 30-60 seconds too fast, and then trying to maintain. I probably killed the tendon around my ankle this way and some knee.
I still went too fast: 5.68 Miles in 50:00... 8'49" pace. I tried starting at 6.4 mph, but my entertainment options on the TV were limited. Also, someone asked to "borrow" the remote for the TV. I did not see it return, so I was stuck on the current channel unless I wanted to break stride. Because of this, I sped up to wrap up. Such are the perils of a treadmill in a gym.
