Death by Rowing = 500m sprint

I ditched swim practice and rowed a 300m warm up and did a 500m row for time instead. Absolutely painful, I have to go lay down........

Here is my breakdown:

meter - time - watt - s/m
500m - 1:34.2 - 419 - 37

Splits:
meter - time - watt - s/m
100m - :18.1 - 472w - 40
200m - :18.3 - 457w - 36
300m - :19.1 - 402w - 35
400m - :19.2 - 396w - 38
500m - :19.6 - 372w - 37

Here is the World Record as of about 1 month ago:
