Tempo run....?

Well, last night I attempted a 4 mile tempo run. Apparently a tempo run is like this.... Run 10 min easy, Run 20 min at 30 sec slower than your 10k race pace, then run 10 min easy.

I think maybe I ran the 20 min at my 5K race pace, cause I was literally dying at about 35 min. I made it back to the house in 40 min, but was spent. I really wish I'd get my garmin in, so I knew what pace I was actually running.

I did lift weights afterwords and worked my arms a little bit.

Note to self: Dont eat Sonic on the day of a run.
