Can I keep up with a wocker?

We are possibly getting a puppy here soon from a very good wocker (working English cocker) in the states. She would be our second dog and companion to our field line Brittany (3yo). Our Brit has obviously a lot of energy but is definitely leveling out. We train in agility and other dog sports very regularly, 2 or 3 times a week. On her off days we do long walks/hikes, anywhere from 1 - 2 hours depending on the weather and heat. We also have a dog walker come twice a week while I work, and she is willing to come in every day while puppy is young to let them out and play with them.

I guess I’m just psyching myself out and thinking I won’t be able to keep up with a working cocker. Did you guys have to train a settle/off switch? How hard of puppies would you consider them?
