if i started running from where i am now faster than the speed of light could i bump into myself and trip myself up before i begin running?

No.

To exceed the speed of light by running I think you'd either be folding space with the Holtzman Generator or engaging the Improbability Drive. But neither leads those time warping tachyon particles the Borg use, sorry.
Don't try and break the laws of physics on your own. This is a job for a professional

There's an interesting story of one of the scientists working in the collided had his head in the path if the proton beam as it fired up. He survived, just.

I thought that had already happened yonks ago...........
Boy 1;- My dad's so fast, he can kick a ball at one end of the football pitch, run down and save it from going in the goal!
Boy 2;- My dad's so fast, he can throw a cricket ball, run down to the wickets and hit it with his bat!
Boy 3;- My dad's so fast, he works for the council!
Boys 1 & 2;- Huh?
Boy 3;- Yeah! He finishes work at 5 o-clock, and he's home by half 3!

If you understand and agree with the laws of physics then the question could never be actually answered, if a particle with mass tried to get to the speed of light then its mass rises precipitously so by the time it get to that magic figure it would be of infinite mass and require infinite energy to move it which means there is not enough in the universe, in answer to this then you would have to change the laws of physics to achieve it thus our understanding and logic on the matter would dissolve and without difined theories and laws to guide us we cannot guess the outcome.
The laws of physics stops this from ever happening and so would logic in that sense hence theoretically there are too many problems with actually going back in time and seeing yourself although travelling into the future is and has be shown to be possible by simple changing how time moves for the observer.

After just quickly looking the incident up, it wasn't at CERN, it happened in the soviet union in the late 70's.
Half of his face paralysed, lost his sense of smell and has suffered seizures the rest of his life.
Some could say he was still lucky, it was estimated he received a dose of radiation far higher than should be fatal, doctors believe that as it was such a narrow path of radiation through his head is the reason for his survival.

Aren’t laws just guidelines rather than a list of dos and don’ts?
As it happens, I’ve been trawling through the archives to find some information about MRI scanners for Pete999’s Chernobyl thread but to no avail. I did however come across a study that found that no woman has ever shot her husband while he was doing the dishes. I wonder how many partials they had to smash together to find that out? Anyways, I did come across the story of Anatoli Bugorski who was working on the U70 synchrotron when he stuck his head in the path of a proton beam. He saw a flash of light brighter than a thousand suns but survived the ordeal. That is one way of turning yourself into a human guinea pig I suppose. I hate to think the kind of tests they performed on him over the years. Mind you, the bragging rights will have turned him into a Soviet hero.

This is the same incident I was referring to, I don't believe many if any other person has been struck by a proton beam from a super collidor.

When I was an apprentice I worked on the extension to the cyclotron building at Hammersmith Hospital, was an interesting piece of kit, 3' thick solid concrete doors covered the entrance, made isotopes for cancer patients.

Pointless/interesting fact of the day
Incidentally the extreme bright light he perceived is mirrored by experiences of astronauts these flashes of light are collectively known as phosphenes where neurons along the the visual cortex and in the brain are stimulated by means other than carrying the signal created by a photon of light. They were well documented on the Apollo missions especially those doing high radiation runs.

i love a good paradox
i personally do not think travelling backwards through time will ever be possible, forward relative to other on planet earth, is possible but not feasible

Depends on how you look at this, technically you are incorrect, any object moving faster relative to another object experiences time slower, people on a commercial jet flying high above are actually growing older slower than those on ground but given the small speed differences relative to cosmology values you will not ever conceive it, to note the SatNav's use atomic clocks that have to be corrected for the speed difference relative to the user looking up where he is on earth, if we did not allow for this compensation then the technology could not work... it's a mind bending concept to believe time runs slower for the SatNavs then it does for anything on earth but that is why Einstein is one if not thee most famous scientist out there.

i mean something noticeable like years, like if i went away for a year for and the earth had aged 50 years
are you still here?or are you chasing your arse back to 1873?

it may be possible to see yourself with hair again if we can figure this out

You might enjoy studying 'causality' which says that:
Causality is the relationship between causes and effects. It is considered to be fundamental to all natural science, especially physics. Causality is also a topic studied from the perspectives of philosophy and statistics. Causality means that an effect cannot occur from a cause which is not in the back (past) light cone of that event. Similarly, a cause cannot have an effect outside its front (future) light cone.
Also, how many runners are there in your thought experiment? You? Your faster you? You and your faster you?.......Are matter and energy being conserved in your experiment?

just me, if im running faster than light then i should be able to run into myself, or at least see myself begin running (running round a sphere and not in a straight line)
would the "me" that i run up behind be solid matter though?
elsparko - good man for making the effort to ponder some hard things about the Universe and the physics which describes it.
I am the one to tell you that space and time are not two distinct abstract things unrelated, unconnected or independent of one another. Eventually you had to know this - sorry to disappoint you.
As Einstein said - 'space and time are modes by which we think but not the reality in which with exist'. This is the gist of special relativity.

like infinity, it technically is not something quantifiable, there is no number bigger than infinity, but if you say infinity +1 there is a bigger number but both are essentially the same
Poor yourself a dram of your favourite whisky, and when it is dark look up at the sky and toast the mystery and wonder of the 'whatever it is' we live in. And Who willed its existence.

Forgetting the impossible task of doing this for a moment -
No it wouldn't be a solid you, you are only seeing information of the past IE like when we look at the stars at night, the light you see is like a video or photo of what was and thus is not solid, like in VR when you believe there is a real person in front of you but it is merely an impression of the past in the form of light.
We're all electricians here (most of us), Surely we can come up with the 1.21 gigawatts and the 88mph needed to travel back in time.
You draw us a picture of the device on the back of a big enough check and we will make it happen.
Ignoring time travel (and several other laws-getting broken)
(No. of Gs splatting you like a bug !)
, you could run thru your image ,as it tries to catch up with you.
But there will be only one solid version of you -
