Running Challenges is a Firefox extension designed for avid parkrunners looking to make their running experience more engaging. By using your parkrun results, this tool allows you to participate in various challenges and earn badges such as 'Tourist', 'Alphabeteer', and 'Stopwatch-Bingo'. Additionally, it encourages volunteer participation by offering purple badges for those who help out regularly, promoting community involvement. This extension integrates seamlessly with your athlete results page, displaying your progress and achievements clearly.

The extension also includes a social aspect, enabling you to view your friends' profiles and track their progress in challenges. Although primarily developed for Chrome, this version is being tested on Firefox, which may result in occasional bugs. It is important to note that the extension is unofficial and not affiliated with parkrun, created by passionate parkrunners to enhance the fun and camaraderie of the parkrun community.
