Running across a tightrope really fast?

It depends on how straight of a line the person can run.  If the person can run in a straight line, then the running might be the better strategy.  If not,  then stick to a slow technique.

Thats an interesting question. On paper, it seems like it would be possible, but I have a hard time imagining it working. Here are my calculations.\n\nFor a human to do a "loop the loop", he would need to run fast enough so that at the top of the loop, the centripital acceleration of his CENTER OF GRAVITY would be at least as great as gravitational acceleration.\n\nCentripital acceleration = (speed)^2 / radius\nAcceleration due to gravity (g) = 9.8 m.secs^2 downward\n\nR is the radius of the loop, H is the persons height.\nWe will assume that the persons center of gravity is H/2 meters above the ground.\n\nAs the person runs through the loop, his center of gravity will travel a circle of radius R-H/2. If his running speed is V, the speed of his center of gravity will be V[1-H/(2R)].\n\n(speed)^2 /radius > g\nspeed^2 > (9.8) radius\nV^2[1-H/(2R)]^2 > (9.8)[R-H/2]\nV^2[2R-H]^2 > (9.8)2R^2[2R-H]\n\nv^2 > 2(9.8)R^2/[2R-H]\n\nV > 19.6R/SQRT[2R-H]\n\nLet us now assume that the person is 2 meters tall. The diameter of the circle must be at least that much. We will assume it is 4.0 meters, so the radius would be 2 meters.\n\nspeed  > (19.6)(2.0)/SQRT(4-2) = 7 meters per second\n\nA person 2 meters high who can manage to be running 7 meters per second at the top of a loop of diameter 4 meters should be able to do it....

when ur on ur hands, push off as hard as u can and snap ur feet down\n\nit will be much easier

Well pretty much you go outside, find a wall, or some walls, and find the fastest way possible to clear them without injuring yourself or others. Try going to Parkour.net for some tips, check out their forums.

i dont think that'll give you too much toe drag. my toes are about that far off my board and im good so unless you doing some really (and i mean really) sharp turns stick with that board- its fine

running on the pavement can put strain on the knees

when you travel faster than the speed of sound.

I wish I could show you how to do it. The best way is to take smaller steps and push downward with a spring in the step. This is a technique used by the Israeli army and you can outrun everyone every time. Kind of a sideways motion.

You cannot get away from friction.  Material properties are also not going to be exact.

Run around with your eyes closed....real fast.

everything can be done in moderation and you can alternate your runs for shorter ones and then one really long one at some point in the week take care of the stress on the knee's though and if you find that you are getting a lot of injury take your running inside on a treadmill as that will ease the pressure on the knees and joints.\nOn the other hand walk does wonders too

It is not possible unless there is some external force to initiate or continue the movement. The initial movement will get off set and reduced  in course of time.

Jump Rope it helps a lot I could jump 3 inches higher because I jump rope and run stadiums. You got to really be dedicated and want it a lot or you wont get it.

You can have your legs broke and stretched.  you'll be in traction for a long time.  very painful.

Fast enough to break important parts of your anatomy if you were to fall off.

tip it over, just make sure you use medium force back up about 10 feet and run as fast as you can to the center of its body.
