HW = 100M LHW = 200M MW = 400M WW = 800M LW = 1,500M FW = 5,000M BW = 10,000M FLW = Marathon So Pacquiao has been the Lineal World Champion in Marathon, 5k, and 800k. Then won 1,500 meters as well. Armstrong won 5k, 1.5k and 800M in one year and was robbed of the 400M. Mayweather only won 1,500m and 800m
Just watching the Worlds in Eugene and it is really impossible for a 800meter runner to win long distance races.
