I enjoy competing in duathlons. My family often struggles to find me on the course to show their support. I want to build an application that will allow them to see my location on the course during a race through a wearable. Remote family and friend could also check in on how my race is going and send words of encouragement and / or donate to charity. It would need a clean simple interface. It would allow the racer auto to push notifications to friends and family notifying the race is starting when the racer signs in. It would need to be secure and racer would need to be control of contacts. The racer would pay for the app, download app, then invite specific friends and family to follow along.
