I have seen little discussion of Helsinki, the world championships this year. I think, if Shaheen were to partake, the race could be the greatest ever with this possible field:
HICHAM EL GUERROUJ, 3:26.00 1500 WR, 3:43.13 mile WR 12:50.24 5,000, Olympic 5,000m gold medal winner, Olympic (once) and 4 time WC gold 1500m
KENENISA BEKELE, 12:37.35 5,000m WR, 26:20.31 10,000m WR, 2003 bronze medalist in the 5,000, 2004 silver medalist in 5,000m, Olympic and world 10K champion
SILESHI SIHINE, 12:47.04 5,000m, World bronze and Olympic silver 10K, 26:39.69 10,000m, 1 of 3 athletes to ever beat both Bekele and Gebrselassie
ELIUD KIPCHOGE, 12:46.53 5,000m, World 5,000m gold, 7:27.42 3,000m
STEPHEN CHERONO, 12:48.81 5,000m, 7:53.63 SC WR, World steeple gold,
ABRAHAM CHEBII, 12:52.99 5,000m, only non-Ethiopian ever to beat both Bekele and Gebrselassie
GEBREMARIAM or BERHANU
Imagine such a field. It is possible, and it would be unforgottable to see that race. There are 3 men ever under 12:40, and one would be in that race. There are 9 people ever under 12:50, and 4 would be in that race.
I think it is possible if everyone stays healthy.
Renato, encourage Cherono to do the 5K! He has already won the steeple.
