Until you do go through training, he needs to be on-leash in an unfenced area. That's my opinion :)... I have a Border Collie, not known to run off, but he would also run off to play with other dogs/people until we went through lots of obedience training and we work with him every day. Now, I can trust him to not bolt, not to say that I'd ever allow him off-leash in a high traffic area (anywhere with cars, people, and dogs is always on-leash!).
A tip just in case he does get away - call his name very excitedly and jump around and run the other way - chasing him will most likely only incite him into a game of chase and he'll keep running! If you attend Obedience and teach him very valuable commands like "stay" "leave it" "here" "wait" etc, in a supportive and gradually distracting environment, it will help you a lot with having more peace of mind and you'll be able to do fun things with him like trail riding.
