Detailed teachers' notes for this activity are available on our NRICH website.

#### Olympic Starters

This is the start of the 100 metres in 1896. In that year Thomas Burke from the USA won the race in 12 seconds.

I wonder how far you could run in 12 seconds.

You and your friends could use a stop watch and then measure how far you ran.

This is the finish of the 200 metres 4 years later. Robert Kerr from Canada won that race in just over 22 seconds.

I wonder if you could run the 100 metres in that time?

Or you could see how far you could run in 22 seconds.

This is the high jump in 1906. It shows Ray Ewry from the United States.

He jumped 1 metre 56 centimetres.

How high can you jump?

See how high 1 metre 56 centimetres is.

Can you find someone who can jump that high?

This is the long jump.

In 1906 it was Ray Ewry who won again, as he won in 1904.

This is a standing jump with no run-up.

He jumped 3 metres 47 centimetres in 1904 and 17 centimetres less in 1906.
