So I decided to do three miles last night on the treadmill, instead of my usual two. Since I got off to a slow start in February, it was a good opportunity to get in an extra mile.
And it was easy peasy! Getting thru the two miles (5 incline, 3.5 speed) was not bad, then I threw in a half mile run (flat, 4.0 speed) and a fast walk for the last half mile (flat, 3.8 speed).
I had a little struggle in a few spots, but talked my way thru it -- visualized the Half Mara route and the castle and Spaceship Earth and "aimed" for them.
I've come to realize that it's important to learn how to fight thru these walls and tough spots, and I'm getting better at it!!
