Usain Bolt's Running Career Ends In Agony

Usain Bolt's Final appearance on the track ended in agony as he pulled up injured running the final leg of the World Championships 4x100 meters relay as Britain beat the United States for a shock Gold Medal.

Bolt, who had to settle for Bronze in the individual 100 metres, had been hoping to sign off from the sport by leading Jamaica to a fifth successive relay Gold but they were already struggling in third when he collected the baton.

As he tried to gain ground, bolt pulled up and fell to the floor with what looked like a hamstring injury.

While hosts Great Britain raced on to win Gold ahead of the USA Team, bolt was tended where he fell but refused to leave the track in a Wheelchair.

The official result recorded that the Jamaicans did not finish but bolt had been absolutely determined to ensure he completed the last race after a matchless career in which he won 19 Major Championship Gold Medals.
