Recently I produced a table of 5k target times for different age groups that were the age-graded equivalent of a 25 year old doing 5k in 30 minutes. This was based on the calculator at runnersworld.com/tools/age-...
I have since realised that the times I produced are still unfair on the ladies as the start point (5k in 30 mins at 25 years) is itself relatively more difficult for a woman than a man.
30 mins is 2.32 times as long as the world record for a 25 year old male athlete but only 2.02 times as long as the WR for a 25 year old woman. To be the same as the men's target of 2.32 times the WR the women's target time at 25 years should be 34:20 and not 30:00.
The alternative way of looking at it is that the 30 yr old ladies time stays at 30 mins and the men's is adjusted down to be only 2.02 times the 25 yr old men's WR - ie 26:09
I am more than happy to redo the calculations either way but I would like to hear which way people think I should go - extend the ladies times or reduce the men's ?
