The men's marathon world record could be smashed by half a minute in Berlin tomorrow morning, according to the man responsible for compiling what is the finest elite field of all time.

Reigning Olympic marathon champion Eliud Kipchoge, triple Olympic track champion Kenenisa Bekele and former world record holder Wilson Kipsang will do battle over the streets of Berlin, with all three targeting the existing two hours two minutes 57 seconds world record.

That mark was set by Dennis Kimetto at the 2014 Berlin Marathon and the last six world records have come on the German capital's flat course.

With Kipchoge coming into the race fresh off the back of his 2:00.25 Nike-sponsored marathon under artificial conditions - and not counting towards official records - earlier this year, the Kenyan is odds-on to break the world record tomorrow.

"This is like a dream come true," Mark Milde, Berlin Marathon race director, told Telegraph Sport.
