This is getting interesting.
I did about a 3 mile hike yesterday in a somewhat hilly area. What surprised me the most was how tired I got just walking up and down hills. I was also surprised at how tight I was.
Today, back on the treadmill, I decided to up the ante a little. I decided to go back to the run 4/walk 2 intervals that I have used in the past. I know that it means pushing the run interval up, but, hey - we're all an experiement of one.
The good news is I still stopped at 2.25 miles, so I haven't completely gone over the edge.
We'll see later today how the pain is.
ORN: 2.25 miles, 29 minutes, run 4/walk 2
