If something is up and running, it is in operation:
- The engineer soon got the air-conditioning up and running again.
- The Transfer Council is up and running.
- The Conference has tried for over 10 years to get this organization up and running.
What words/phrases/idioms could we use to describe a person who is fully prepared (for the day, work etc.) and is already working?
The other day I heard "I am up and running" but it sound like a metaphor to me because a system or a machine is usually up and running. So, what would you say to describe such an active person, presumably an early riser, who is already up and... well, running errands, working hard etc.?
