Warhorse (light)

A light warhorse costs 100 G.P. and can carry up to 500 lb. Under an average burden, light horses travel 40 miles a day on roads, 35 on flatland, 15 in rugged country and 5 in very rugged terrain.

Unencumbered, a mount moves 50% farther; heavily encumbered, 50% less. Riders without the Riding skill risk a fall (a save vs Dexterity) whenever they go faster than a trot, and those without Mounted Combat fight from the saddle at the non-proficiency penalty with a 50/50 chance each round of being unhorsed.
