Daily Cardio Load tells you when to back off

What we’re expecting

Officially confirmed on June 4, 2026, Daily Cardio Load measures accumulated cardiovascular strain, calculates your maximum training capacity, and recommends the right training load and rest timing. It's built for athletes managing periodization without a coaching platform.

Daily Cardio Load tracks how much cardiovascular stress you've piled up over a day, then tells you how hard to push next time and when to back off. It weighs your total strain against your max training capacity and hands you a target. So instead of guessing whether today's run was too much, the watch does the math. Nobody's confirmed the numbers are accurate enough to trust yet.
