Anniversary Games: Part 2

Gabby Logan introduces live coverage of the London Anniversary Games, where a host of British athletes compete in a star-studded field ahead of the World Championships.

Mo Farah returns to the scene of his double Olympic 2012 triumph to run in the 5,000m and 10,000m, and Katarina Johnson-Thompson and Greg Rutherford are also competing. Six-time Paralympic champion David Weir competes in his final race, fittingly in the stadium which saw him win a trio of gold medals at London 2012.
