I think difficult all the problems my athletes had this year can happen again, all together.
CALEB NDIKU suffered for a tendon from last year, immediately after WCh. He wanted to defend his indoor title, and trained in winter always with pain, with little volume and no speed endurance workouts. Since in that period I was not in Kenya, I had no direct knowledge of the real situation, and also an expert athlete like Caleb did the mistake to think to be competitive for the World Indoor ("I feel pain, but let me try till WCh, after I take a period of rest").
Running 3 indoors competitions made his situation worse, and also his training from May was not easy, since he continued to suffer with his tendon.
He joined me in Iten immediately after Eugene (he wanted to cancel Prefontaine, but for athletes with NIKE contract to run there is a must), and in one month of time increased a little his shape, but in training never was able to stay with athletes as Cornelius Kangogo and Victor Chumo, runners about 13'10" - 13'12" of value. He won Trials because the event was particularly weak, and because, in any case, he has great personality. However, during all the training camp he never was able to train on track, and also after a session of fartlek of medium level had to rest completely for the next two days. For me, it was not a surprise his elimination in the heat.
THOMAS LONGOSIWA instead had a very good training season, starting his first two DL with good results (13'01" in Shanghai and 13'02" in Eugene), but between Eugene (28 May) and Oslo (9 June) he suffered for strong pain in the stomach, and this was the reason of his bad performance in Oslo.
When was back Kenya, he went to the hospital, and the investigation discovered he had Amoeba, so went under treatment with strong antibiotics (and Trials were very close). He ran Trials still under treatment, and was a big mistake by AK not to give him a wild card on the distance (also looking at his international history). He was called in the training camp directly by the Chairman, Gen. Tuwei, and till last minute hoped to be part of the Olympic Team : his training was good (clearly he was better than all the slected athletes), but at the end was not selected, lost motivation and decided to finish the season, after running in Zurich a race without any stimulus.
JAIRUS BIRECH had a good winter, we planned to grow as shape reaching the top level for Trials. But he did a mistake in Rome (2nd June), looking behind him when was 8 meters only far from the barrier with 300m to go in the last lap, and when looked again in front of him the barrier was too close and he had a wrong step, so, trying to change frequency, fell down with a strong impact with both his knees on the track (he finished the race in 8'11" after standing up). The biggest mistake was to compete 3 days later in Birmingham, since he was not yet able to walk, so had to stop completely training for two weeks, and went Trials with one week of easy training only.
However, the problems were not finished, since, after the heat, he didn't feel ok, went to the Eldoret Hospital, and they found a REAL typhus (still now, his body is not completely ok : he tried to run in Lausanne at the end of August, but his body didn't react in the right way).
Apart these athletes, at the beginning of the season I had other two athletes looking at Olympics : Florence Kiplagat (marathon) and Ronald Kwemoi (1500m).
Florence suffered for a bad injury in one calf, in 2015, from the 10000m on track used as selection for Ethiopian (in Hengelo at half of June), and was lucky to win Chicago with pain and little preparation, because the field was not too much competitive, but after that marathon had to stop till January.
In January, when I went Iten, she was at the beginning of the preparation, overweight and without any shape, and was a miracle (due to her strong motivation for running Olympics) she was able to recover a shape at 80% for London. But the selection of Marathon runners by AK was totally crazy, and frankly nobody could suppose something like this : Visiline Jepkesho was selected, in spite to have a PB 5 minutes worse than Florence, never to have run a Major (Florence won twice Berlin, once Chicago and ran London several times, with one 2nd and one 3rd place), not having any international result (Florence won World CC Championships in 2009, World HM Champs in 2010, was the WR holder of 15 km, 20 km and HM, and the National Record Holder of 10000m on track), and in any case being 2 minutes slower than Florence in the seasonal time. Not only, but the only time she reperesented Kenya (WCh 2015 in Beijing) she was number 20 in 2:36:17.
Practically, AK choose to go Rio with two athletes only, because in Rio Jepkesho was number 86 in 2:46:05.... results fruit of total lack of knowledge or, worst, of come corruption.
Anyway, Florence, instead to fight with Jemima for the Gold medal, had to stay at home, looking Olympics in TV !
About RONALD KWEMOI, he was in the best shape of his life. He showed this winning in DL (Monaco) with the last 100m about 1 second faster than everybody else, and also in the preliminary rounds (heat and semifinal) he gave the impression to be the athlete with more chance to win, in case of a race at medium speed. But, of course, accepting a pace slow for girls in the youth category (2'17" the first 800m), remaining behind (Centrowitz leaded fro the start...), was a big mistake, because when athletes don't run, but jog, everything can happen. It was not a case he fell down, trapped by Suleyman who didn't have any responsibility for this fact, but his chances finished exactly with his fall.
