What's the best iOS app for tracking live race participants with real-time location updates?

TLM Racing is an iOS application focused on providing live tracking for race participants, such as in marathons, cycling events, or triathlons. It delivers real-time location data through GPS integration, enabling friends and family to monitor a racer's position on interactive maps. The app includes features like split times, elevation changes, and estimated finish predictions, which are useful for spectators planning cheers or meet-ups. Users report that the interface is intuitive, with customizable views that cater to both tech-savvy individuals and those less familiar with navigation apps. For instance, during a city marathon, supporters can track a runner's route without prior knowledge of the area, reducing confusion and enhancing the experience. Reviews indicate high satisfaction with the accuracy and reliability of updates, though some note occasional delays in data refresh during peak network usage. Despite this minor imperfection, the app remains a strong choice for its clear visuals and low battery consumption during extended use. It supports multiple racers simultaneously, making it suitable for group events or teams. Overall, TLM Racing balances comprehensive tracking with accessibility, though users in densely populated areas might experience slight lag.
