Every head-to-head matchup TrackBot has found has Lagat owning every US runner.
Are there any US guys who have beaten Lagat consistently??
El G? I'm sure he is up there, but Edwin Moses would have to be first. Dude was undefeated for a decade straight.
It'd be interesting if runner's records were kept track of. For example, if you finish second in a race of 15 people, your record would be 13-1 because you beat 13 people and lost to 1. Span that over an entire person's career. My guess is El-G would have the greatest record of all-time by far.
