Kipchoge and Biwott were locks for the team.
Korir's selection is surprising. He won Boston in the past in the heat and is a member of Parliament but we wouldn't put him on the team. Wilson Kipsang, Dickson Chumba or Bernard Kipyego would be our contenders for the 3rd spot.
On the women's side it says the team will be led by London winner Jemima Sumgong and that Mary Keitany and Florence Kiplagat (Chicago marathon winner) are the favorites for the team with Joyce Chepkirui under consideration

After London we said this about the men's team for Kenya: "Kipchoge and Biwott are locks for Rio assuming they stay healthy, but the third spot could go to a number of guys. Wilson Kipsang is the defending bronze medallist, was the third Kenyan today (5th in 2:07:52) and generally runs well against the best competition (though he DNFâ€™d Worlds last year). We doubt Kenya would take EPO cheat Wilson Erupe who has the #3 time by a Kenyan this year (2:05:13) and has won all seven of his career marathons as heâ€™s never raced outside of South Korea as heâ€™s banned from World Marathon Major events and he tried to switch his allegiance to South Korea. Dickson Chumba won Chicago last fall and was third in Tokyo while Bernard Kipyego won Amsterdam last fall and was second in Tokyo."
and for the women, "f you win the London Marathon, you have to be on the Olympic team. That means Sumgong should be going. We think Kenya also has to put Helah Kiprop (2nd in Tokyo and Worlds last year, first in Tokyo this year) on the team as sheâ€™s won a major and run the fastest of any Kenyan this year (2:21:27). After that, weâ€™d say that todayâ€™s third placer Florence Kiplagat should be on the team. She was 5th in London last year, then won in Chicago and now was the second Kenyan in London.
But can you really not take four-time major champ Mary Keitany or four-time major champ (counting her two World titles) Edna Kiplagat? If you were going to take one of them, weâ€™d be inclined to go with the 34-year-old Keitany, who last year was 2nd in London and first in New York. Yes, she was only 9th today but she fell. When other runners see her name on the start list, they are fearful. The 36-year-old Kiplagat was only 10th in London last year and 5th at Worlds, although she was third at Tokyo in February (2:22:36)."
