We spent a fabulous week at CN in 2006 and have decided to try to get back to Jamaica for another visit later this year. I'm currently training for a marathon and would like to be able to get in at least a few runs while there. Is there any one resort that would be better for this? I would likely just try to run on the beach or around (and around) the resort. (I know the fitness centers likely have treadmills but I try to avoid them).
