Beenzycling

Strava art on a home trainer: ride indoors and your activity draws a shape on the map, out at sea.

Pick one of more than 300 single-stroke drawings, scaled to the distance you choose and placed in open ocean, where no road bends the line. The trainer connects over Web Bluetooth (FTMS, Tacx FE-C or a power meter, plus a heart-rate strap), and the ride is exported as a FIT file and published to Strava as a virtual ride.
