What is a really fast furlong?
When breezing consider 12 seconds an eighth (furlong) to be a strong pace. The longer the breeze, the harder it would be to maintain that speed. Green Monkey, who was a record setting sales auction horse because of the speed he breezed, breezed in about 10 seconds for the eighth of a mile. Races typically publish the speed of the first quarter, for sprint races you might see a time of 21 seconds and change (change refers to a fraction of a second).
