Kenya will send a big squad of 29 athletes including three former world and Olympic champions to the Diamond League season opener in Doha on Friday, which also serves as first stop in the road to Rio Olympics.

Kenyans Asbel Kiprop, who has ruled out going for the world record in the 1,500m this season, will be the man to beat over the shorter 800m distance while Ezekiel Kemboi, who has continued to defy the odds to hold on as the best ever steeplechaser will meet the man who beat him at the Beijing Olympics, and his training mate Brimin Kipruto.

"I have done enough test runs in Kenyan meetings and am comfortable with what I have attained so far. But this is a level higher and it will require full commitment and hard work to beat the world's best," Kiprop said on Tuesday from Eldoret.

Kiprop came close to breaking Hicham El Gourej world 1,500m record (3:26.00) in Monaco two seasons ago when he clocked 3:26.69.

But he has opted to focus on reclaiming his Olympic title in Rio than run for the world record. However, should the field in Doha inspire him to bring his best, then he will be ready for a fast time.

"The world record? That is very early in the season to think of. Maybe we will get some fast time in the run up to the Rio Olympics and Doha am stepping down to the 800m. Maybe on my return to Monaco in July," he said.

For the steeplechasers, Kemboi is aware this might be his last chance to impress at the Olympics having won two titles in Athens and London. He has nothing to prove and apart from the norm of winning, he will be happy with a top three finish.

"We are just starting off after a long recess and I believe we will do just fine to get the right results. Kipruto is strong contender and I have to be at my best form to beat him," he said.

The Kenya squad of 29 athletes will depart for Doha on Wednesday as they launch their campaign for the Rio Olympics.

However, despite its early season position on the competitive calendar, the Doha Diamond League has traditionally attracted the elite of athletics, resulting in numerous records being broken and personal bests being set.

The 2016 edition, set for May 6, won't be an exception, with 38 champions and 80 medalists from past Olympic Games and world indoor and outdoor championships heading to the Qatari capital to open their Diamond League campaign.

On the men's side of the programme, six athletes have won Olympic gold: LaShawn Merritt, Aries Merritt and Christian Taylor of the U.S. and Kenyans Asbel Kiprop, Ezekiel Kemboi and Brimin Kipruto.

Fourteen have been crowned world champion outdoors - nine last year in Beijing - and nine earning a world indoor title.

Additionally 21 have won an Olympic medal, 30 a World Championships medal and 19 a World Indoor Championships medal. In all, 20 men have bagged gold at a global competition and 43 left with medals.

In the women's events Doha will welcome 18 global champions and 37 medallists. Of those, Olga Rypakova and Veronica Campbell-Brown have struck Olympic gold, 11 have claimed world titles outdoors -- seven in Beijing -- and seven indoors. Furthermore, six have finished among the top-three at Olympic Games, 21 at world championships outdoors and 22 indoors.

Overall 206 athletes (125 men and 81 women) will compete at the 2016 Doha Diamond League representing 50 nations from five continents.

Hosts Qatar will field 14 athletes, while Kenya's presence will be the largest with 29 - composed of 20 men and nine women - with the United States bringing the largest women's contingent with 14.
