Runners exhibited as artwork at Tate Britain

Martin Creed cheered up the Turner prize no end seven years ago, when he won the award for a piece that consisted of a gallery's lights being switched on and off.

Now the artist is back with a new work that is likely to prove just as irritating to traditionalists.

Creed's Work No 850 is a single athlete running at top speed through the Duveen Galleries at Tate Britain - every 30 seconds, all day, every day.

Visitors to Tate Britain will see a runner streak past them, dashing "as if their life depended on it" according to the artist's instructions. After a runner has made the 86 metre sprint (which will take around 12 seconds) there will be a 15 second pause, like a rest in a piece of music. Then the next runner will dash forth.
