Karen + 300 DU Workout

Karen: 150 wallball, using 20 lb med ball to a target 10'
I started doing sets of 15 for the first 6 sets. They felt really good and initially I was holding back to keep up the rounds of 15. I then did 2 sets of 10, and then 11, 11, 8 to finish up.
I waited about 5 minutes and then did 300 DUs. I wasn't sure going into it if I was going to do 500 but decided on 300 as I was getting tight and didn't want this to be a killer WOD really.
I couldn't resist to do a workout outside

last time I did this was 10/16/12 - Karen in 9:42 and then 300 DUS in about 5:56 but I also did that one in the early morning.
I did that one as 15 sets of 10 reps.
