Crossfit Mixer

I combined two of my favorite xfits and it went like this:
run 400 meters
50 air squats
run 400 meters
max pullups (31)
run 400 meters
50 air squats
30 minute involuntary brake for a mtn biker
run 400 meters
max pullups (30)
run 400 meters
50 air squats
run 400 meters
max pullups (25)
run 400 meters
50 air squats
run 400 meters
max pullups (21)
Then 200 situps to make it a solid half hour work out.
I liked it. I ran barefoot and it sprinkled during the last 3 runs.
Right ball of foot is a trifle tender. But all in all I felt good.

My Left shoulder still aches. I'm a little concerned.
