AT Fitness Tracker

A fitness game for a group of friends. Log the miles you walk, hike, run or ride, and everyone moves together along the Appalachian Trail, Springer Mountain to Katahdin.

An interactive trail map with landmark stories, a pixel-art camp that grows with the miles, badges for every hiker and a wildlife-spotting minigame. It began life as Oregon Trail DLE.
