The career of Emmanuel Korir has been a story of running fast at exactly the right moments. Last year he collected Olympic gold. Earlier this season he was at his best to win the World Championship. And although he lost last week in Brussels he showed his timing once more when the stakes were high at the last Diamond League meeting in Zürich .

The pace was pretty fast, but that didn't daunt Korir in the slightest. He watched from afar how the pacemaker dropped out. He made his way through the field when Jake Wightman, the man who beat him last week, went to the front. He was closer already when Marco Arop found an extra gear and seemed to take an unassailable lead.

And then Korir made his move. He went past Wightman in a flash. Then gained rapidly on the tiring Arop and passed him just a few meters before the finish. Job done, timed to perfection, Diamond League victory ensured and a new world leading time on top of that. There is little doubt now that Korir is currently the greatest 800m runner by far.

While Mariano García wasn't really known for fast outdoor times, he had definitely shown his qualities earlier in the season when he won the world Indoor title. He had also made his intentions quite clear, as he wrote on social media how he would take the lead 500m out and planned to win it from there.

As it turned out this script was followed to perfection. No athlete was ready to force the pace, so García moved forward, took the lead as they approached the bell and lead the pack into the final lap after a pretty fast 52.07 seconds.

Jake Wightman, Ben Pattison and Mark English were close behind, Pattison lost ground as Eliott Crestan moved forward before falling away again. English hung on solidly to take a second bronze (he had won bronze at the 2014 EC as well) as Wightman came very close to the lead.

But in the end it wasn't quite close enough. García held on, finished in a new PB and came away with a well deserved gold. His brave decision to take the lead early had paid off.

Kinymal was perhaps the favorite on paper, but history was against him. Never before had an athlete been able to defend his Commonwealth games 800m title.

The pace was slow during the first lap, and when the field, tightly bunched, took over 55 seconds to complete the first lap it was clear that the second lap would be a lot faster. Kinyamal and Bol were in the lead, and they steadily increased the pace, creating a considerable gap between them and the six others. Into the final straight Kinyamal was stil leading Bol and although both athletes were clearly struggling none of the others could get really close.

And so Kinyamal stayed just ahead of Bol and reached the finish in delight, achieving something that had never been done before. Only one runner found something extra in the final straight. Young talent Ben Pattison had been in the rear during most of the race and found himself boxed in when he wanted to move forward. Still, he managed to outsprint all the others and claimed a creditable bronze.
