The Bank of America Chicago Marathon over the weekend was a race of its own.

Ruth Chepngetich of Kenya run  2:14:18 the second-fastest time in history, missing the World record by 14 seconds.

Emily Sisson, finished second in a time of 2:18:29 to set  American record for women. She obliterated  Keira D' Amato record by 43 seconds.

In men's marathon, Kenya's Benson Kipruto roared to victory with a new personal best of 2:04:24, the third fastest time ever run in Chicago marathon.

Seifu Tura Abdiwak of Ethiopia (2:04:49) was contented with second place, after failing to defend his title. Another Kenyan John Korir closed the podium in new personal best of 2:05:01.

But there was something else about the exquisite performances of Benson Kipruto and John Korir - taking on the family mantle.

Dickson Chumba, who is a renowned athlete is elder brother to Benson Kipruto. Chumba won Chicago marathon in 2015. It's for this reason that Kipruto was emboldened to defend the family prodogy.

Wesley Korir, a world class athlete is a brother to John Korir. The former won Boston marathon in 2016 and he has been inspirational to his younger sibling.

Whereas Dickson Chumba is still active and he is preparing for his next marathon Wesley Korir seems to have passed the baton fully to his younger brother John Korir.
