Semenya leads the pack on final day of competition
By Christian Radnedge
LONDON, Aug 13 (Reuters) - Caster Semenya will attempt to reclaim her 800 metres title on the final day of action of the World Championships in London on Sunday.
The South African, who was awarded gold retrospectively in the event in 2011, already has one medal to her name this week, after winning bronze in the 1500 metres on Monday.
However, it's the two-lap race that is her strongest, the event in which she won Olympic gold in Rio last year.
Semenya's race is among the highlights of the final session at the London Stadium.
Having taken back the women's 4x100 metres relay title from Jamaica the day before, the United States will aim to repeat that feat on Sunday in the 4x400 metres relay.
The final event will be the men's edition of the race as hosts Britain go for one last gold.
The day's action begins across the city at The Mall, where the men and women's 50km race walk gets under way at 0645 GMT, with the 20km versions following afterwards. (Reporting by Christian Radnedge,; Editing by Neville Dalton)
