Day 3: 5 x 400 at my goal mile pace

Quick update, because it is time for bed! I did this workout on the treadmill today because I didn't get finished with work until around 6:30pm, and by that time it was already dark :(
I felt really good about the workout! I started at my goal pace - 7.1mph which is roughly an 8:30 min mile - and ran the first .25 mile (400m) interval. Then walked afor about .15 miles and then did the second .25 mile interval at 7.2mph. Then with each interval I went up .1mph, ending at 7.5mph for my 5th one, which is actually an 8 minute mile pace!
So I pushed it today, and I'm hoping this means my body is in good shape to tackle this goal. Doing a 400m interval is a lot different from running an entire 5K at that pace, and I did feel tired, so there's still work to do. But I'm up for it :)
Alright, bedtime. I'm beat!
