Harrier League Cross Country

The Harrier League is a cross country running league with seven fixtures across the North East of England in the 2017/18 season across the winter months from September ’17 until March ’18.

The Harrier League is unique to other cross country fixtures because the senior runners are divided up into slow, medium and fast packs. In the senior men’s race, the slow runners start first followed 2 minutes 30 seconds later by the medium pack runners, then a further 2 minutes 30 seconds by the fast pack runners.

In order to progress to the fast pack, runners must first run in the slow pack and finish in the top 10% of finishers, this entitles them to run from the medium pack. If they then finish in the top 10% from the medium pack, then they can run from the fast pack.

Teams are split into three divisions and final team positions are calculated within each division by ordering the first six runners (four in the senior women) by race time. This is the total time elapsed from when the slow pack starts to when the runner crosses the finish line. Let’s answer one interesting question, what would the results be from the past weekends fixture without the handicaps, i.e. if everyone started from scratch.

The code for this analysis was written using R and the tidyverse. The full code can be found on Github. Let me know if you’d like me to answer other questions about the harrier league.

Senior Womens

We will look at the results from the previous race at Druridge Bay. In the senior women’s race there are four counters, any team with less than four runners will be removed from the final results. Now, we can calculate the position of each runner within each division by the actual running time of each runner.

First we need to download the relevant information, since the results are available as an HTML table, the package htmltab can be used to select the table containing the individual results

These results are then cleaned up, removing any guest runners and extracting the division of each runner from the club field.

Now we write a function which calculates the results for one division. This can be re-used for the men’s results by accepting the number of counters for each team as an argument to the function (4 women to count, 6 men to count). We remove any clubs who fielded incomplete teams and select the top counters ordered by the position supplied in the raw_results dataframe. We then calculate the total points for each time, by summing the positions (lower is better) and concatenate the names of the counters into a single string.

Now, we are ready to calculate the results given positions. But instead of using the race time (actual time + handicap time), we use the actual time to determine individual positions within each of the three divisions. We then use the previously defined function get_results_one_division() to calculate the final score for each team in each division:

Here are the results for the women’s division one, two and three:

Senior Men

In the senior men’s race there are six counters, any team with less than six runners will be removed from the final results. Now, we can calculate the position of each runner within each division by the actual running time of each runner.
