Great Cycle Challenge is a mobile application designed for Android users to record the distance of their bike rides while participating in a fundraising event to fight kids' cancer. Developed by Minimal Digital, this free app uses GPS to track each ride, which automatically syncs with the individual and team fundraising profile pages, updating the distance ridden towards the event goal.

Apart from tracking the distance, the app allows users to update their ride and fundraising goals, post blog updates, view past rides, thank sponsors, enter offline cash donations, and view leaderboards. With Great Cycle Challenge, users can test their limits and ride as far as they can for a good cause. However, it is essential to note that continued use of GPS running in the background can significantly decrease battery life.

Overall, Great Cycle Challenge is a must-have app for cyclists who want to make a difference by fundraising for kids' cancer while doing what they love.
