The World’s Best 10K Race (WB10K) is a yearly international event that takes place in Puerto Rico with approximately 10,000 participants. This study seeks to reduce interference between participants during the race by improving the corrals design and assignment of participants to corrals. Interference is quantified as the number of times a participant passed another participant at predetermined checkpoints. A theoretical lower bound for the number of interferences is presented. Regression analyses are used to estimate the participants’ finish time. The finish time estimates are used to assign bib numbers, and consequently corrals, to participants. In addition, Monte Carlo simulations are combined with the regression-based assignments to find the corral design that minimizes the expected number of interferences. Six corral policies are proposed and evaluated. It was found that the most effective policy to reduce interferences is an implementation of waves (i.e., sequential corral release).
