Transform city streets into time-unlocking workout labyrinths using real-time shadow tracking. Navigate daily-changing obstacle courses before shadows shift and paths disappear.
You're running through downtown at 2:47 PM, your phone buzzes "Shadow path closing in 3 minutes," you sprint toward a building's shadow to unlock the final weights station, complete the dumbbell circuit just as the shadow reaches the marker, and watch your name climb the live Colosseum leaderboard as hundreds of other runners in your city race against their own disappearing shadow paths.
