According to this article from the internet today it reads as if Bekele have planned to run the 5000m race weeks ago.
Bekele retains his title and sets up date with destiny
Kenenisa Bekele of Ethiopia clocked 27 minutes and 8.33 seconds to win the men's 10,000 meters gold medal at the 10th IAAF World Championships.
He ran through on the rain-drenched track, clocking a last lap of 54.25 seconds to outkick his team mate, Sileshi Sihine and Kenya's Moses Mosop.
The winning performance which the defending champion produced was, prosaic, rather than dazzling, in what was something of a muddle of a race.
Sihine could never quite match Bekele's sprint finish off the final bend as he finished in 27:08.87 to add world silver to the Olympic silver he collected last year, with Mosop gaining a lifetime best 27:08.96 to go with his bronze medal.
Perhaps it is the question mark over whether Bekele will now attempt the elusive distance double here in Helsinki, for so many the spiritual home of distance running. Certainly, tonight he produced a run that suggested that he did not wish to over-exert himself in retaining the title he won two years ago.
In Paris in 2003, it was a matter of the changing of the guard, as he succeeded Haile Gebrselassie (who was missing from the final of a World Championship 10,000m final tonight for the first time in 12 years). Come Sunday, and the final of the 5,000m, Bekele has an appointment with destiny, for no man has successfully won 5,000 and 10,000m golds at a global championships since Miruts Yifter, another great Ethiopian, did so at the 1980 Moscow Olympics.
"It was decided quite a while ago," Bekele said of the decision to run both events here.
Thus, the kilometres ticked by steadily, if unspectacularly, with the champion deep in the pack, no better than 11th or 12th, and unconcerned at the identity of the leader or the lack of pace in the race.
Not until the 17th lap, run in 62.22sec, did the pace pick up from its langour, and significantly that was when Bekele cruised up on the outside of the pack to move into the top three.
By this stage, the leading group was down to nine men: three Ethiopians, a Ugandan, Boniface Kiprop, Nicholas Kemboi, of Qatar, two Kenyans, Zersenay Tadesse, the Athens Olympic bronze medallist, and Abderrahim Goumri, of Morocco.
But then the pace dropped again, to 66 and even 68sec laps, so the bumping and nudging around the fringes of the group seemed to increase, Tadesse particularly finding himself knocked wide on a couple of occasions.
Perhaps even Bekele's rivals felt no one else could win: after all, this morning's edition of The Nation newspaper in Nairobi had described the possibility of any other result "would have caused one of the biggest upsets in the sport".
With a kilometer left to run, Martin Irungu, the Kenyan who based in Japan, went to the front, but not with a change of pace that would detach him from the rest, and as the bell tolled for the last lap, there were three Ethiopians at the front, with Mosop the first chaser.
But this was not to be a repeat of four years ago in Edmonton, when Charles Kamathi exposed the first frailities in Gebrselassie's armoury. It is easy to overlook, especially because of his four World Cross Country doubles as well as his Olympic 10,000m gold, that Bekele is, after all, only 23.
There was plenty of strength in his legs for the last-lap burn-up, although maybe (and only maybe) there was some brief signs of strain in his body in the final 100 meters. But, significantly, not once he reached the sanctuary of the finishing line.
And as to whether Bekele can match Yifter, or Lasse Viren or Emil Zatopek, we will discover more when the 5,000m heats are staged on Thursday.
