End-of-the-ride tying up is akin to human athletes' cramping, I believe. Low
fuel/electrolytes probably the cause. Still, with the massive muscles that DO
cramp, you get a much more severe result in the horse.

Myoglobin in the urine to the extent that it turn coffee colored indicates
massive muscle damage. There is no way that I know of that this would not
show up in a blood test that included muscle enzymes a several days later.

The two are different, but the damage done is equivalent if there is dark
urine.
