Is this what you are looking for?  You'll have to do the math...

http://63.80.222.118/library/archive/proceedings/sc93/ChokePoints/index.html

"During endurance exercise (7.5 to 11.5 miles per hour), horses will
typically use muscle glycogen at a rate from 0.5 to 1.5 mmol/kg/min. The
remainder of the energy generated at this rate speed comes from fat
oxidation. "
