As a serious runner, there is no way that I would run for an extended distance without my phone on me. First of all because I would rather not have to drag my injured self out somewhere to ask for help, rather than being able to call for it from my phone. Whenever I do triathlon training, I would also not think of leaving without my phone, as I tend to go for 30-40 mile bike rides into remote areas, and having a way to communicate with the outside world in case the worst happens (equipment malfunction, injury) is preferable. I don't think I have a single watch that can last more than 7 hours of continuous GPS usage, between running and biking, so I'd like to see what the battery life on the Apple Watch looks like before passing judgement.
