What do the numbers mean?

How does the scoring work?

Thanks to, we take the first 250 finishers from each race and remove any results which cannot be attributed to an existing runner.  We then calculate the percentage of the remaining top 100 who achieved a personal best. This is repeated for the last 3 runnings of the event, from which we take the average score, then removing a fixed figure for each time the event did not take place or was short in the last 3 years. The final figure is put into an algorithm which calculates the “jegmar” rating for the potential to gain a PB.

Criteria to be considered for the top 10

  • Average of more than 1,000 finishers over the last 3 years
  • Taken place and been correct distance at least twice in the last 4 years
