Today I did cardio, and I upped my incline walking speed from 3.00 to 3.3-3.5. I started out and did the first half at 3.5 and I noticed I was getting tired fast, I wanted to make the rest of my wind sprints and the last one I wanted to do at 7 mph. So, I slowed it down a little to 3.3. My legs are a bit sore, but no big deal, I have all day tomorrow to rest up for LBWO on Sunday
