Marathon

Successive world records for the marathon for both males and females from inception to 1987.

The question of interest is whether the data can reasonably be used to predict future world records. In particular, do the data provide evidence that in time women can be expected to run faster marathons than men?

The Men and Women's results are stored separately.
