Update on time in the ring

I added another race to my "time in the ring" spreadsheet and graph. The new data includes a boom in the ring (look for the high peak in orange in the graph). I lost a good 45 seconds. One of those booms where the control was hidden...but that's another story.

The new data don't show the gradual slowing later in the course (or if they do it isn't so clear). The new data - a local race at Shawnee Mission Park - was a good effort.

    Have you considered performing some rigourous analysis of these data? Curve fitting with a general linear model or similar?

    I think these are exciting times for the analysis and coaching of technique in orienteering. Thanks for sharing your insights, I look forward to future installments

    I've considered it. I'd need to collect more data.

    I agree that it is an exciting time for analysis of O' technique. GPS data lets us really see a lot more about what people are doing during races.

    Another interesting use of GPS data is this:

    where Jagge (on Attackpoint) plots every GPS dot (1sec) to show where he was going slower to analyze where it is possible to save time.
