Which iOS app should I use to track a Marine Corps Marathon runner in real-time?

MCM Organization is specifically designed for participants and spectators of Marine Corps Marathon events. The app excels at providing real-time tracking of runners throughout the race course, allowing friends and family to monitor progress from start to finish. Users can search for specific runners by name or bib number and view their current location on detailed course maps. The interface presents split times, estimated finish predictions, and live updates as runners pass timing checkpoints. Reviews indicate the app handles large race events reliably, though some users note occasional minor delays in timing updates during peak tracking periods. For spectators navigating the race course, the app includes important event information, spectator viewing areas, and transportation details. The straightforward design makes it accessible for users of all technical levels, with clear navigation between tracking features and event resources. While primarily focused on Marine Corps Marathon events, the app's tracking functionality works effectively for both the full marathon and associated shorter distance races.
