 I also would like to correct my previous response-the water loss I quoted
 was in kilograms, 
 not lbs-so it was actiually 65-110 POUNDS of water! That's 8 to 12 gallons
 of water.
 We measured sweat losses of yearlings trotting on a treadmill a few years 
ago-
 they were doing a steady trot for 30 minutes and lost 8 to 10 lbs of weight
 (we corrected for fecal losses) in only 1/2 hour. Schott et al estimated 
that 
 endurance horses in a 50 mile race lost 6.6 to 9 liters of water per hour.
  Of course losses vary with conditions.
 Bottom line-let those horses drink!
 
 Also-to convert glucose from mg/dl to mmol/l you merely divide by 18-so 100
 mg/dl
 is 5.5 mmol/L.

Thanks for the conversion. 

Ok, Beth tells me that glycogen to water ration with stored glycogen is 1 to 
4, a pound of glycogen burned will release 4 lbs of water into circulation. 
Does anyone know what the rate of glucogen burning, per hour, is, in lbs in 
the endurance horse?
