Wanyonyi takes dramatic goldpublished at 18:19 British Summer Time 10 August
Men's 800m final
Goodness me, what a finish!
Emmanuel Wanyonyi has won the gold medal by 0.01 seconds! He was leading throughout the final lap but was so nearly caught by Marco Arop of Canada, only holding on on the final stride.
Kenya's Wanyonyi takes gold, Arop gets silver. Algeria's Djamel Sedjati, who was the world leader this year and favourite tonight, takes bronze.
GB's Max Burgin faded in the final 400m and finished 8th.
