Paper Title: Running with Cases: [1] URL http://bit.ly/iccbr running with cases Conference / Journal 25th International Conference on Case-Based Reasoning Publication Date June, 2017
Running a marathon personal-best (PB) needs careful planning. It starts with a target-time to aim for; a time that is not so easy that you will feel untested, but also not so hard that you run the risk of ruining your race because you hit the wall. But a target nish-time alone is not enough to ensure marathon success. Runners need a race-plan or pacing plan to achieve this time, a segment by segment plan for how fast or slow they should run, tailored to the course. A good pacing plan will help a runner to manage their e ort throughout the race, segment by segment, hill by hill This is especially important during the crucial early stages of the marathon, when many go out too fast, and helps to reduce the risk of hitting the wall later in the race.
The main contribution of this work is to introduce a novel case-based, recommender system for helping marathon runners to identify, and plan for, new personal-best nish-times. We describe how to construct suitable training cases from conventional race-records, and how to use these cases to predict a PB time and recommend a tailored pacing plan. We evaluate the results using data from the last 12 years of the Chicago marathon.
