Core, the manufacturer of the core body temperature sensor, has announced an app update that will introduce the first generalised heat training zones for users as well as an updated Heat Strain Index designed to help athletes perform in high temperatures.
We recently reported that the Core sensor itself has been widely adopted in the WorldTour, as Core announced a partnership with 10 teams including BORA - Hansgrohe and Canyon/Sram. A race to stay cool is also a component of the WorldTour performance arms race these days.
