Treadmill Incline Workout

Tonight I did one of my brother's signature incline workouts on the treadmill. I walked 3.3 miles at 15% incline and 3.5 speed for 30 min then 2 miles at 11% incline and 4 speed for another 30 min. A couple days ago Tom Jennings graciously switched me from the 50K to the 100K at Oil Creek. I wanted to get a 50 mile qualifier in, so I can enter the MMT lottery this December. I can't wait for the challenge!
