Lactic acid is a substance that increases in the body during hard exercise. The maximum intensity at which one can exercise without increasing lactic acid is called “LT,” and is said to be related to endurance exercise capacity, such as marathon running. This service determines this “LT” based on sweat lactate measurement and suggests the optimal marathon pace for you.

There will also be an exclusive HIALCH membership offer for participants!
