Good week: Kenya’s Dennis Kimetto broke the marathon world record in Berlin with an astonishing time of 2 hrs 2 mins 37 seconds. Not bad for a former farmer who only took up marathon running a couple of years ago.
Bad week: Welsh hurdler Dai Greene has parted company with his coach Malcolm Arnold after 5 years. Under his tutelage Green became the 2011 world champion in the 400 metre hurdles but has been struggling with injuries since.
Stat of the week: 61 mins 12 secs: the time it took Dennis Kimetto to complete the second half of his world record breaking marathon race in Berlin.
Pledge of the week: Usain Bolt believes he can break his 100m and 200m world records. He said: “If I can get a perfect season where I’m working well, without any injuries, with no time off, I’ll definitely have the chance to break the 100m world record and run a sub-19 second time in the 200m.” (BBC Sport)
