Geoffrey Kamworor- Cross Country, track and Marathon
Kamworor has had a decorated career in cross country, 10,000m and road racing. He trains alongside Kipchoge in Kaptagat.
After four-time world cross-country victories (two in senior and equal number of wins in the junior category), four world half marathon titles to his name and two wins at the New York City Marathon, Kamworor's career was hit by an injury in 2020.
After recovering from a fractured tibia following a motorcycle accident in June 2020, Kamworor later suffered a stress fracture, but made it to the Kenyan team to the World Cross Country championships set for February 18, 2023 in Bathurst, Australia. He finished sixth at the National Cross Country trials in Ruiru.
Emmanuel Korir - 800m
In the past two years, Korir, who went to Kimuron Secondary School in Elgeyo Marakwet before flying to US for academic pursuits, has proved to be 800m world record holder David Rudisha's perfect replacement.
The 27-year-old masterful track star is a defending Olympic and World champion.
At last year's World Championships in Oregon, Korir ran a textbook tactical race to win the 800m title. The world will be watching his moves as eyes a defense of his world title in Budapest.
Evans Chebet - Marathon
Chebet, 33, has two World Marathon Major titles in Boston and New York under his belt. He won the two major marathons in 2022.
But he is yet to fly the Kenyan flag in a global 42km contest. Will 2023 be his year to represent the country?
The Kapsabet-based athlete registered his first win at the 2019 edition of Buenos Aires Marathon before writing another decisive victory at the 2021 Valencia Marathon.
Kelvin Kiptum - Marathon
He arrived with a bang when he made a sensational marathon debut, taking victory in 2:01:53 - the fastest 42km debut and the third fastest time in the World.
The world will curiously be watching to see whether Kiptum, 23, was a one-hit wonder, or a consistent athlete rising gradually to stardom.
Kiptum's personal best in the marathon is just 44 seconds outside Kipchoge's world record.
Women
Faith Chepng'etich
Kipyegon - 1500m
She later finished sixth at her debut 42km race at the New York City Marathon in November. This year, Obiri, the world is watching her moves in road running.
Peres Jepchirchir - Marathon
After basking in glory at the 2022 Boston Marathon, the Olympic champion is looking to another successful 2023.
Jepchirchir, 29, missed the 2022 World Athletics Championships due to her hip injury and another opportunity for a world title attempt will present itself in August.
Whichever race her manager decides, Jepchirchir will be among women marathoners whose participation will be keenly followed this year because of her stunning performances, previously.
Jepchirchir won the 2020 Olympic gold medal in a time of 2:27.20. She won the 2021 New York City Marathon with a time of 2:22:39, becoming the first athlete to win the Olympic gold medal and the New York City Marathon in the same year. She won the 2022 Boston Marathon with a time of 2:21:02.
