Gallop Cantrip (3.5e Spell)

[[3e Summary:: The caster using this cantrip can give a crea­ture within 10 feet (usually a mount) a sudden burst of speed that doubles the creature's land-based movement rate for one round. The move­ment is arrow-straight, though a saving throw vs. spell with a +3 bonus is allowed to avoid an ob­stacle such as a snare, pit, or precipice, if the creature or its rider knows the obstacle is there. Lame or exhausted creatures might require a system shock check for survival if the DM de­cides this is appropriate. Unwilling creatures with more than animal intelligence receive a saving throw vs. spell to negate the effect.
