400M Run & 50 Squats

I'm working abroad this week. Hotel WOD - For time, four rounds of 400m treadmill run and 50 squats: 20:52 (PR). The last time I completed this WOD was 14 Jul 08. I did it in 23:47. I cannot believe I only dropped a couple minutes off my time. Boy, I'm slow. I'll tell you though. I felt much better this time and felt no pain in my back like last time. I guess something is working for me. :-)
