I don't run, for many of the same reasons you give, but I do fairly high speed long distance walking (about 7km/h or 4.5mp/h for 20 km). I get that 'flow' state after about an hour and the high kicks in maybe after about an hour and a half and lasts until well after the walk is finished.
Fast walking has its advantages over running like less injuries, easier to maintain the pace, and it's less painful than running and more pleasurable. Getting the high means it is much easier to motvate myself to go every day.
