hard workout and now off to Chicago!

Today I did a crazy workout- it was 4 by 4 miles (3 miles at 6:35 followed by one mile at 7 min pace) then one mile at 6 min pace. The paces were slower than a workout but after doing 16 miles it doesn’t feel so slow : ) I hadn’t ever done a long run + workout. Usually I just run long for my long run. I could tell that this was a great workout…however now I am in the airport on the way back to Chicago- I might be a little stiff when I arrive : )
