Kenyan runners line up in Karvana Bulgaria on Friday in search of top honors during the World Half marathon.
Former 5,000m world champion Eliud Kipchoge leads the country's quest to retain the world title as he represents the country in his first half marathon event.
He goes into the competition with an enviable record of having represented the country at several major world championships and picking four medals in the process.
Kipchoge who turns 28 next month, made his debut in the half marathon in Lille last month where he finished third after clocking 59:25.
Kipchoge is among the athletes tasked with retaining the half marathon title won by Kenyan runners in Nanning China two years ago.
Pius Maiyo is the other major prospect in the men's race. Maiyo goes into Friday's race just a few months after clocking his half marathon career best of 59:25.
Philemon Limo who finished seventh in the World Cross country championships in Punta Umbria in 2011 is also in the men's team alongside John Mwangangi and Steve Kosgei.
The women team is equally formidable and will be led by Peninah Arusei who finished third in the same event two years ago when it was held in China.
In the absence of defending champion Florence Kiplagat, Arusei is tipped to succeed her fellow Kenyan on the podium.
Arusei holds a season's best time of 68:12, which she managed in Paris when she finished second in March.
She will face strong opposition from teammate Pauline Njeri who beat her in the Paris half marathon after clocking 67:55 in April.
Veteran Lydia Cheromei, 35 is also in the team. She holds the sixth fastest time in the half marathon this year having clocked 67:26 in Prague.
Cheromei was one of the London Olympic hopefuls but missed out at the last minute. Her Personal Best time in the full marathon stands at 2:21:3
Priscah Jepleting who finished fourth during last year's world athletics championships in Daegu in the 10,000m event is also in the team.
Her half marathon debut ended in third place in Lille with an impressive 68:35. Jepleting is a late entrant in the team after she was drafted to replace Lucy Kabuu who withdrew due to injury.
Pascalia Chepkorir Kipkoech completes the female line-up for Friday's race.
Men: Eliud Kipchoge, Philemon Limo, John Mwangangi, Pius Maiyo and Steve Kosgei.
Women: Pascalia Chepkorir, Lydia Cheromei, Pauline Njeri, Priscah Jepleting and Peninah Arusei.
