Graphical Splits Displays

More sophisticated methods of analysing split times, using WinSplits and SplitsBrowser:

Times for Harthill have not yet been supplied. 
The Harthill time has been interpolated from the Treeton and Woodsetts times, assuming the same pace (speed).
Results will be updated when Harthill times become available

SplitsBrowser sample from Relay:

Interactive graphical presentation of individual and relay split times in Splits Browser. 

Splitsbrowser uses Java; as it loads, you may get a message asking if you want to block the potentially unsafe application; click No
Select class I for Individual or R for Relay
Select who you want to check (All or specific individuals/teams, by clicking on them). 
The graph shows how each competitor has lost time, compared to the fastest time for each stage, which corresponds to a horizontal straight line. Column widths are proportional to the fastest time for the stage. Lost time is indicated by your line sloping downwards.  If you run at a constant speed relative to the leading time, you will get a steadily dropping line.  If you lose time on one stage, the downward slope for that stage will be more steeply downwards than other stages.

Various alternative analysis formats are available.

The graph above is for the first 7 relay teams (class R) were selected.  The horizontal red line from Start to 1 and 2 to 7 shows that the Clowne A team recorded the fastest (or equal fastest) time for these 6 stages.  The line drops from 1 to 2 and 7 to Finish, showing they were not fastest on these stages; it is the yellow line for Maltby for 1 to 2 and the Black Deadwood line for 7 to Finish that are horizontal, indicating they producing the fastest times for these stages.  

The mouse pointer was on the 2 line; pressing the right button shows the fastest time recorded for this stage in the relay was 44 min, 53 min for the individual. 

The numbers to the right of the runner/team name show split and calculated lost time for each runner/team on the stage. Selection of times displayed is based on tick boxes to the bottom right. 

You can select alternative formats, e.g. compare with a specific runner, your own team or (individual) yourself.  Note: Abnormal lines: No time for retiree Caroline Billis at Grange.  Retirees are indicated by an asterisk (*) to the left of the name, except Kevin Dews who retired at Old Denaby.

WinSplits Online

Click link for  Split times, WinSplits Online  (Table)

WinSplits is commercial software that helps analysis of split times from events

For each runner, position, name, club, finish time, time behind the winner and times and positions at each checkpoint are shown. There are two time rows. The upper row contains the split times, i.e. times between two subsequent checkpoints, and the lower row contains the total times, i e accumulated times from the start to a certain checkpoint. The positions are displayed within parentheses, on the upper row the ranking for the stage and on the second row the current race position.  The appearance of the split time list can be altered by changing the settings at the bottom of the page. Fastest times are printed in red.  Red background is used where WinSplits thinks you have lost time compared to your usual progress.  Read more about this (and other) topics in the WinSplits Help pages.

In this example, runners are listed in finish order.  For each stage, the fastest time is shown as red type on a light background.  The error criterion is set to 5%, which is relative to overall time adjusted for the stage.  Times in black with a pink background reflect an error, e.g. Anthony Gorundni lost time on stage 8.   Where the difference is attributable to a slower running speed rather than an error, it is not highlighted in pink.


Colours are used to make certain information in the table appear more distinctly.

red text colour Red text colour indicates best split time and total time, respectively.
blue text colour Blue text colour indicates that the split time or total time is among the three best.
grey, italic text colour Interpolated times (times were interpolated before uploading, so this was not used)
pink background colour Pink background colour means that time was lost on this stage, time taken was 25% longer than expected (taking overall time into account). See WinSplits Help for more information. 
light yellow background colour The light yellow hue of the background of the upper time row for each runner indicates that the times are split times.
darker yellow back colour The somewhat darker yellow hue of the background of the lower of the time rows for each runner indicates that the times are total times (or real times if that setting is active).

See Bonus Content which shows the head-to-head performance (win - draw - lose) between one runner and each other.  The leg placement legend is half way down the page; position 1 (red), 2 or 3, 4-6, 7-10, 11-20, >20

Both utilities have split times for retirees up to the retirement point. In SplitsBrowser, the order of retirees has been randomly changed. The graphs are based on published results (but please let me know if you find any errors)
