RunSaturday has built some charting tools in order to help you, the athletes, to analyse your results from the weekly parkrun time trials.
This analysis isn't fully documented yet - but I'm hopeful some of you will work out how to use it :)
If you spot a problem in the analysis and charting then please talk to us. If there's a problem in the underlying data, however, then please contact parkrun who manage, store and provide all the data shown here.
Please use the control panel below to set your chart preferences, then hit
