The video shows a group of three horses testing the Varenne monitoring system during training at Stall Courant, Sweden, in September 2024.

Varenne is a training tool that improves performance and welfare in harness racing. It is comprised of 3-7 ProMove-V IMUs and a heart rate belt.

The online interface is designed to be used by a driver or trainer during training, showing live data about heart rate, symmetry and pace.

The post-analysis interface includes interactive graphs displaying the symmetry index, heart rate, speed, altitude, stride length, stride frequency and a map showing where the horse was exercising during the measurement.
