Take away his water and food. It sounds bad, but it works.
Make sure that once you do catch him walk him out and release him again, catch him several times before working him. You don't want to anticipate work. However this is the concept that makes the running him until he lets himself get caught work: you want it to seem very peaceful when he is near you and uncomfortable when he is away from you. Don't give him treats until after he is caught! Positive REINFORCEMENT, you are REINFORCING a behavior not coaxing him, otherwise like you said he takes the treat and runs away.
The thing about running him you have to be mindful of is your body language and HIS body language. Relax (stop chasing him and show him your "flank") if he licks/chews, or if he faces you. Walk towards him, keeping your eyes down and kinda in a diagonal (otherwise it is seen as aggression). If he walks away from you chase him HARD again. If he takes any steps in your direction or has his head follow you stop and wait for a minute. I like this method if you either have him in a small space OR if you have multiple people with you. Personally, I worry about this method as you really do need a professional who knows how to do it-- it's not something to try as an amateur.
