I could use a nap

530 am Crossfit.
Feeling run down. Actually I felt tired in the pool yesterday but I expected that it was due to Monday's 2hrs of intense training. Tuesday was just 1 hr swim so I expected to feel better this morning.
Nope.
Got to Class late because I was so groggy when the alarm went off.
Strength was Deadlift. Got 280. Didn't feel like doing the wod. Wanted to keep lifting. Just didn't want to run my heart rate up.
But I did it anyway.
For time:
12 burpees
30 then 20 then 10 g2o 45lb plate
9 burpees
30 20 10 kbs
6 burpees
30 20 10 kb cleans
22min. I think I was last in class. For some reason this was really hard. Might have been he wod. Might have been sleep, consecutive work days. Who knows.
