Runner Modification (3.5e Feat)
From D&D Wiki
Runner Modification [Racial]
Whenever you have all your four libs free for use, you can use all the four limbs for movement. Your base land speed increases by +10 feet, but you cannot make attacks for obvious reasons. While sprinting, you can, once a minute, speed burst for one round as a full-round action for 8x speed. To change from bipedal into quadruped creature and from quadruped creature back to bipedal, it takes a move action.
- Extreme power burst
When standing on four legs, mechanoid can make jump checks as if it had a running start and without any maximum height penalty.
