David Rudisha is on top of the world once again after the London 2012 star stormed to 800 metres glory at the World Championships.
It has been a topsy-turvy three years since the Kenyan lit up the Olympic Stadium with his remarkable, world-record performance.
Beijing was the 26-year-old's first major global championship since then, having missed the 2013 edition in Moscow through a knee injury - an issue followed by a calf complaint..

However, with rival Nijel Amos of Botswana surprisingly missing the final, Rudisha highlighted his undoubted quality over two laps of the Bird's Nest.
Running from the front, the reigning Olympic and 2011 world champion controlled the pace and kicked on around the final bend, crossing the line in one minute 45.84 seconds.
"I am delighted about this gold medal," Rudisha said, having beaten Poland's Adam Kszczot by 0.24 secs.
"It means a lot to me, especially after all these disappointments I had this year.
"During the last month, I had a problem with my speed, but when I solved it and got my speed back I knew that no matter if the pace in this final will be slow or fast, I can win."
Rudisha was the star of the show in Beijing, but the history man was Amel Tuka.
While unable to replicate his world-leading time, the 24-year-old's bronze was Bosnia-Herzegovina's first medal of any colour at the World Championships.
"This is the first medal for me at my first World Championships and it is also the first medal for my country," Tuka said. "It is like some big dream coming true.
"I have been training only for six years. I am really proud for my people in Bosnia-Herzegovina and I know they are celebrating now."
