Me, I would have yelled, as soon as I saw that they weren't paying attention. Depending on the gravity of the situation I would go "Bip-bip", "Heads up!" or "HEY!!" Faster than ringing a bell and it works.
As I read you you had the right of way and they were the ones not paying attention, so don't feel guilty for buzzing them. The driver probably saw both you and the joggers, and had an idea that you would have trouble passing them. Not something you should count on, of course, but I wouldn't feel guilty about swerving into the lane either, if the alternative was crashing into them.
Excellent tips above for avoiding that kind of situation later - riding further out in the lane and keeping all traffic around you "in mind".
