The Bupa Great Manchester Run this Sunday will see two of the greatest long-distance runners of all time go head-to-head.
Kenenisa Bekele and Wilson Kipsang have never raced each other before but the stage is set for an enthralling encounter in the 10km race.
Bekele, the world record-holder for the 5000m and the 10,000m has recently turned his attention to the track, firstly, edging out Britain's Mo Farah in a thrilling Great North Run race last September.
Last month, the Ethiopian made his marathon debut - clocking an impressive 2:05.04 to win in Paris. And he has since revealed he wants to add the marathon record to his growing list of accolades.
To do that, he must beat Kipsang, currently the fastest man over 26.2 miles ever with a time of 2:03.23. After a troublesome few years with injury, if Bekele can overcome his Kenyan rival here, then he would announce to the world that he really is back.
In the women's race, Tirunesh Dibaba will be hoping to retain the title she won last year. The Ethiopian, the world and Olympic 10,000m champion, has also made her marathon debut this year, finishing third in London.
The 28-year-old will be the massive favourite for this, though, with the race distance at her preferred 10k.
