The answer is that in the Olympics all of the competitors are the best in the world and at their peaks.
And there is a distinct advantage to drafting off of someone at a good pace for the majority of the race.
The advantage negates a slight advantage in fitness.
No rabbits in the Olympics means no help for that first half of the race.
You can lead wire to wire if you are significantly better than the field.
In 2004, Lagat had the 1500m world lead in 3:27 and was ranked #1 on the year for a full season's of work.
El G wasn't going rabbit him in the Olympic final. And that plan worked.
Ngeny almost beat El G in the world record mile run in 1999.
He was too good to lead him the next year in the Olympics.
I agree that Bekele maybe should have pushed the 5000 pace in 2004.
But he was coming off of a 10,000 double and was being chased by El G, the 1500 champ and Kipchoge who beat them both in 12:52, the fastest 5000 championship time ever the year before.
Would you want them sitting on your back for 12 laps?
Bekele pushed the later laps after starting slow in 2008 and it worked brilliantly.
Kiprop has an Olympic Gold medal and three World Championship Gold medals from sitting back and blasting the field.
I understand going with that strategy again.
The one time a fast pace worked in a finals was the 1999 1500.
El G had a countryman that made the final act as rabbit and set a fast pace where he held off Ngeny 3:27 to 3:28.
But without that early pace setting, El G wasn't going to make it a 3:27 race on his own.
