I'm biased having lived in Eugene and having a thing for the distance guys, but if you're discussing track you have to consider this guy:
He's ran the mile in under 3:50 at least 14 times (including once in the Pre Classic in Eugene, fastest mile ever ran in US)
He broke the mile record by over a second running it at an amazing 3:43.13
He holds the 1500 record at 3:26
He holds the 2000 (ok admittedly an obscure race but still) at 4:44
He won both the 1500 and 5000 in Athens
He also won the 1500 at the world championships in 1997,1999,2001,2003
