Who, what and when information: 2025 Chicago Marathon

A preview of this 12 months’s version, together with which athletes to be careful for and find out how to be in contact with all of the motion.

John Korir is hoping to turn into simply the sixth male athlete to defend his Chicago Marathon title this Sunday (October 12) however he won’t have all of it his personal method in opposition to a robust area.

The Kenyan received by virtually two minutes final 12 months in a time of two:02:44, a mark which put him eighth on the marathon all-time record.

If Korir does cross the end line tape first once more then he’ll comply with within the footsteps of Steve Jones (1984/1985), Luíz Antônio (1993/1994), Khalid Khannouchi (1999/2000), Evans Rutto (2003/2004) and Samuel Wanjiru (2010/2011).

Not solely is Korir focusing on victory in Chicago however he desires to turn into the second man in historical past to run a sub-2:01 marathon. Solely the late Kelvin Kiptum, who ran his world file of two:00:35 in Chicago two years in the past, has damaged the two:01 barrier over 26.2 miles.

With two victories out of two this season, Korir’s preparation for Chicago could not have been higher. The 28-year-old received the Boston Marathon with 2:04:45 again in April and adopted that up by triumphing over 15km at July’s Boilermaker Highway Race in New York, operating 42:44.

Competitors shall be fierce in Chicago nonetheless and one athlete to observe shall be Uganda’s Jacob Kiplimo. Again in April, London Marathon occasion director Hugh Brasher said that Kiplimo was set for “essentially the most fascinating marathon debut ever”, including {that a} first authorized sub-two hour marathon was “not inconceivable”.

Circumstances in London had been hotter than standard although and Kiplimo battled the warmth to run 2:03:37 for second, inserting solely behind Sabastian Sawe within the British capital.

The Ugandan demolished the world half-marathon file with 56:41 in Barcelona eight months in the past however his transfer to the marathon was a step into the unknown. Now he has one beneath his belt there’s a feeling, with extra conducive situations for quick occasions, he can run so much faster.

Kenyan trio Timothy Kiplagat, Amos Kipruto and CyBrian Kotut cannot be discounted both in Chicago. Kiplagat has the second quickest mark within the area with 2:02:55 and ran that point finally 12 months’s Tokyo Marathon, the place he completed second to Benson Kipruto.

Kipruto additionally received the 2022 London Marathon so he is aware of the sensation of topping the rostrum at a marathon main. Kotut in the meantime has a greatest of two:03:22 and positioned third at this 12 months’s Boston Marathon.

American hopes will possible lie with Conner Mantz, who positioned fourth in Boston again in April, ending simply 4 seconds behind Tanzania’s Alphonce Simbu – now the world marathon champion – and Kotut.

Mantz’s 2:05:08 on the storied course was the second quickest ever by an American in Boston, solely behind Ryan Corridor’s 2:04:58 from 2011. There isn’t any doubt that Mantz shall be focusing on Khannouchi’s 23-year-old US marathon file of two:05:38 in Chicago [Boston is not a record-eligible course, primarily its point-to-point nature and significant net downhill elevation drop].

Britain’s Marc Scott can also be within the area and can goal to higher his greatest of two:11:19, set in London final 12 months. Scott has raced calmly in 2025 and needed to pull out of this 12 months’s London Marathon resulting from a persistent knee damage. He ran 64:05 for seventh at September’s Nice North Run.
