hit the ground running

1. Seize an opportunity; begin at full speed. For example, As soon as the front office gave its approval for the new department, we hit the ground running. The origin of this term is disputed. It may come from troops dropped into a combat zone, from stowaways jumping off a freight train as it nears the station, or from Pony Express riders avoiding delay when they changed mounts.
