Several years ago, Athletics Weekly published rankings of best performers at each event based on factors such as global titles, number of years as world record holder and number of world number 1 rankings. Can anyone find a copy or apply up to date rankings?
About 10 years ago they used the same method to try to determine the best overall distance runners, taking into account big city marathon performances and world cross. Bekele came top followed by Nurmi then Gebrselassie.
I suspect Bekele would still be top of overall distance runners but Farah may well head the 10k rankings.
