      Not surprising that it's a great team in these events, but to spare others looking it all up, here are the PBs for the top 3 in each event (making a perhaps-risky assumption they'll actually be selected):

      MEN
      800m
      David Rudisha 1:41.01
      Job Kinyor 1:43.76
      Timothy Kitum 1:43.96

      1500m
      Silas Kiplagat 3:29.27
      Nixon Chepseba 3:29.90
      Asbel Kiprop 3:29.78
      [NOTE: Assuming I read the lists correctly, in the post-El-G era there are only 7 total @ sub-3:30 (including R Ramzi, who I would prefer not to include, but anyway); here are 3 of the 7.]

      5000m
      Isaiah Kiplangat 12:54.18
      Edwin Soi 12:52.40
      Thomas Longosiwa 12:51.95

      3000m Steeplechase
      Brimin Kipruto 7:53.64
      Ezekiel Kemboi 7:55.76
      Abel Mutai 8:01.67

      WOMEN
      800m

      Hellen Obiri 3:59.68
      Eunice Sum 4:05.90
      Faith Chepngetich 4:03.82 [iirc, she was named to their WJC team]

      3000m Steeplechase
      Milcah Chemos 9:07.14
      Mercy Njoroge 9:16.94

        If true, that's pretty amazing. I think I'm safe in saying that no one has run remotely that fast in a really significant negative-split 800.

          The great Jim Ryun ran negative splits in several of his 800m races.

            Well, once at least, in the 1966 Terre Haute race--which was just over two seconds slower. This just points up how staggeringly rare it is in top-level races.

              Rudisha's run is 0.72s faster then any other high-altitude 800m... and that was his 1.42.84 in Nairobi in 2010.

              Next bests:
              1:43.71A Japheth Kimutai Nairobi 2003
              1:43.76A David Rudisha Nairobi 2011
              1:43.80A Philip Kibitok Nairobi 1996
              1:44.0A Robert Kibet Nairobi 1989

              Data from: http://www.alltime-athletics.com/m_800ok.htm

              I've never got a good sense of the altitude impact at this distance. It didn't seem to hinder performances in Mexico City in 1968. Is the lack of depth here just reflective of a lack of races?

              If there is a negative effect, then Rudisha's performance would go close to Performance of the Week (maybe nudged by Eaton 8-) )

                The historical consensus, as far as I know, is that altitude here is a wash, with no overall negative impact on times.

                  Not only didn't hinder but probably enhanced. Doubell tied the WR.

                      Enhanced? Sounds like you're unfamiliar with the actual effects of altitude: Less gravity, and air resistance, that's it for the positive. No way 800 m is "enhanced", as there's an aerobic phase before they go anaerobic towards the finish. I lived in Puno, Peru (3900 m+), much higher than Nairobi's less than half that, similar to Denver whose "Mile High" altitude is exaggerated in its effect on athletes. Even did a hokey modified Pentathlon (100m in place of 200m), so maybe can claim a World Altitude Record (with lotsa asterisks, starting w/ event composition), so know of what I speak. Besides, this is the first time I've ever seen such an outlandish claim, even if it's conceded that both Lou Jones 1950s PanAm Games 400 m record and Bill Toomey's long-standing Deca record benefitted from altitude--but 400 m is the limit (as regards specific Olympic distances, not counting Indoor ones.

                        The 800m trials results posted above are incorrect with respect to places 2-3. The correct top 3 results (= Kenyan Olympic 800m selections) were:

                        1. David Rudisha 1:42.12
                        2. Timothy Kitum 1:43.94
                        3. Anthony Chemut 1:43.96

                        The IAAF itself is the source of this confusion. Its report on the race is consistent with the top 3 listed immediately above, but the men's 800m results listed below the race summaries say something different.

                          All well and good but you haven't explained the world record. Nor the fact that #2 was 2 tenths back and Doubell ran his last 200 in 25.8. Keino clearly wasn't slowed much by the altitude at 1500. Maybe some athletes fare better at altitude. And Rudisha has just run 1.42.12 in Narobi (5889').
                          Outlandish? Me thinks not. At worst altitude may neither help nor hinder the 800m.

                            According to coach Renato Canova, who was there, Rudisha did negative split, but it wasn't 52/50.

                            He gave the following splits for Rudisha over on LetsRun: -

                            200 - 24.8
                            400 - 51.2 (26.4)
                            600 - 1:16.8 (25.6)
                            800 - 1:42.12 (25.3)

                            Or laps of 51.2/50.9. Still incredible running!
