The Bluetooth Special Interest Group (SIG) has finalized standards for running and cycling sensors, paving the way for a new generation of smart devices to monitor performance. The new standards, known as profiles, allow manufacturers to measure and transmit information such as speed, distance, and cadence in a universally recognizable format. They build on similar guidelines published for heart rate monitors, used in devices such as the Polar H7.

Perhaps the most high-profile Bluetooth-connected fitness device so far has been the general-purpose Nike+ FuelBand, which measures exercise performance using a proprietary algorithm — the opposite of an open standard. The Bluetooth SIG's new profiles, on the other hand, appear to be aimed squarely at dedicated sensors for specific activities, likely to be favored by amateur and semi-professional runners and cyclists.
