The UX of a big city marathon
How the organizers of the Chicago Marathon successfully ferried pedestrians across the course during the race

Organizing and executing a successful marathon in a large city like Chicago is not an easy task. Planning starts the day after the previous year’s marathon and continues for a full year; right up to the day of the race. There is a seemingly endless list of factors to consider:
- street closings
- paid personnel
- volunteers
- registering runners
- race bag pick up locations
- pedestrians and traffic
