Pull ups and Burpees

for time:
50 pull ups 3:12
10 burpees 4:02
40 pull ups 7:54
20 burpees 9:39
30 pull ups 12:28
30 burpees 15:38
20 pull ups 17:28
40 burpees 22:41
10 pull ups 23:20
50 burpees 29:24

burpees, especially the rounds of 40 & 50, really sucked.  I did alternating grips throughout the pull ups, most traditional, but did quite a few mixed grip and chin grip.

Nice WOD!
