HA'S THERMAL
The 3D live-tracking feature allows you to follow how the athletes use the available lift. Here's Chikyong Ha (KOR) turning tight circles in a thermal coming off a mountaintop. The tracklog allows you to see the shape and drift of the thermal as the athlete turns in the 'core', or region of strongest lift. Ha is in 27th position, en route to Turnpoint 7 Titlis.
