We have collected and analysed finish times for 4 million marathon and half marathon runners, from thousands of races taking place around the world over the past two decades. This data provides fascinating insight into how fast the masses run, and how factors such as gender and age can affect finish times.
The marastats website allows runners to view these statistics and to generate personalised reports which show them how they compare to the masses.
The mathematically inclined may be interested in knowing that the average marathon and half marathon finish times presented on marastats.com are median finish times. Median values are deemed to be of greater interest than mean values.
