Brigid Kosgei and Ruth Chepngetich to use controversial shoes in London Marathon

Kenyan duo Brigid Kosgei and Ruth Chepngetich will use controversial shoes worn by Eliud Kipchoge in the London Marathon on Sunday.

Kenya's Kipchoge broke the two-hour barrier in an unofficial event in Vienna last October when he wore the platform Alphafly Next% shoes.

While the shoes allowed by World Athletics' regulations, they are estimated to improve running economy by up to eight per cent.

Kipchoge's record led to calls for the Nike shoes to be banned, but women's marathon world record holder Kosgei is adamant the runner makes the difference rather than the footwear.

Asked which shoes she would be wearing in the her London Marathon title defence, 2019 champion Kosgei said: "The ones Kipchoge will use.

"You know the shoes could not run. It is someone who can run, it's not the shoes, it does not depend on the shoes.

"If I use the training shoes and the body is not there, you cannot run good. So for me it's just the body which enables me to run good, it is not the shoes."

Kosgei's fellow Kenyan -- reigning world champion Chepngetich -- also confirmed she would wear the shoes.

Kosgei and Chepngetich said their training had been interrupted by the coronavirus pandemic, with their training camps both closed temporarily, leaving the pair having to train alone.

At the Chicago Marathon in October last year, Kosgei set a world record with a time of 2 hours 14 minutes 4 seconds, but she will not be targeting a better time on Sunday.

"We did not get a group like last year, (when) we are in groups together we just had to push each other. So it's not like in Chicago but I will try," she said.
