Tile hunting comes from apps such as Squadrats and VeloViewer. The board divides the city into 2,217 map tiles, each about 240 m across. Every tile that a runner passes through counts as explored, and it stays explored. Grow your biggest fully explored square and cluster. Use the planner to route a run through the tiles you're missing
