Sir Mo Farah is Britain’s most decorated Olympic track and field athlete. Gold in the 10,000m and 5,000m at the London and Rio Games complete an extraordinary Olympic double-double.

From humble beginnings in Somalia, Farah came to Britain at the age of eight leaving behind his twin brother, a few words of English but a natural talent for running.

The story follows Farah concentrating on the marathon distance and then switching back to the track with the aim of more Olympic glory in Tokyo 2020.
