A fast track is a dry, properly graded dirt track that provides even, solid footing for horses during a race. Ideal weather and proper maintenance help create fast tracks. If the surface becomes slightly moist from a brief rain or other moisture, the pace slows a little but usually will not affect results much, since good footing is still available. A muddy track slows the pace considerably, with deep, saturated mud that can help slower horses keep pace with otherwise faster horses out of the gate.
