Challenge Family app for iPhone and iPad

One app for all of your events. Track participants on an events course map, view real-time leaderboards, receive participant progress alerts and important updates from events.
• View & share results and rankings.
• Find event landmarks with the course map.
• Track participants via GPS.
• Accept or decline tracking notifications.
• Receive push notifications for followed participants.
• Take and share event photos with all other spectators and participants using the app.
• Easily follow and stay up-to-date with Marathons, 5Ks, 10Ks and Triathlons near you.

In the Watch app, Apple’s HealthKit is used to collect heart rate and exercise data, and at the end of a run, the workout is saved to Healthkit.

Continued use of GPS running in the background can dramatically decrease battery life.
