Kenya team of 30 track and field athletes finally left for London Olympic Games Monday, confident that they will do better than their last show in Beijing.

Led by the most liked athlete world 800m champion David Rudisha, Kenya team will be among the late arrivals at the games, which were opened on Friday by Queen Elizabeth II.

"We have gone through a successful training program and now the focus has to be on delivering the medals at the Olympics. Kenya will always be a big country in regards to the Olympics and I hope when we parade in London, we will continue to show this development," said Rudisha.

The Kenya team captain will be assisted by Olympic 800m champion Pamela Jelimo. Rudisha, who set a world record of 1:41.09 (Brussels) and later broke it to 1:41.01 in Rieti, Italy in 2010, said he is not under pressure to deliver in London but will let his legs do the talking,.

He joins exclusive lists of Kenyans who have opted to double at the Games. Rudisha will be taking on his traditional 2-lap race and later join other teammates in the 4x400m relays. Others who doubles before are Isabella Ochichi in Athens 2004 and marathoner Tegla Loroupe.

In London apart from Rudisha, Kenya will also have world 10,000 and 5,000m champion Vivian Cheruiyot doing the two events. She will be accompanied by USA based Sally Kipyego.

Team manager Joseph Kinyua, the only official remaining behind with the squad, said six athletes in 5,000m and men's marathon will also be remaining behind and will be linking up with the rest of the team in London on Aug.7.

Kenya is entering a squad of 48 in the games - 43 from track and field - similar to the one they took to Beijing four years ago. The country is taking part in athletics, weightlifting, boxing and swimming.

Kenya wound up in position 15 at the last games in Beijing having amassed 14 medals -6 gold, 4 silver and 4 bronze - all coming from track and field competitions.

"This target was set very high. We are looking at improving on it, which will mean having Kenya's best show in the games. We have the best runners to choose from and all factors remaining constant, that is no injuries to our competitors, then I can say we are in the process of setting anew mark in London. Everyone in the team is now ready and focused on the games. They have got their kit, their allowances and training. We have done our part, it is now up to the athletes to showcase what they have before their international rivals and hopefully, Kenyans will emerge triumphant," said Kinyua.

The athletics program at the London Games does not start until Aug. 3.

An advance party of two swimmers David Dunford and Jason Dunford, boxers Benson Gicharu and Elizabeth Andiego, Mercy Obiero (weightlifter), sprinters Joyce Zakari, Bonface Muchera, Mark Mutai, Vincent Mumo, Vincent Kosgei, Maureen Jelegat, Julius Yego (javelin), Alphas Keshoyian and Sally Kipyego are already in London.
