I hate to tell you but these protons do not start out anywhere near the speed of light. The purpose of the huge superconductive magnets used in these colliders is to accelerate protons to as near the speed of light as is possible.
(they never actually reach this speed, but do come very very close)
So in short, yes it's very plausible to encounter a proton beam of 760mph.
There is an excellent video on youTube that explains the mechanics of the recently built LHC. Check it out it will make things very clear for you
