Our products can be used before, during, and after training and racing. Of course, race day is where athletes often get the most out of them.
During training and racing, athletes generate a huge amount of heat inside the body. In fact, only around 20% of the energy produced contributes to mechanical power. The rest becomes heat that accumulates inside the body.
This is a natural process, but excess heat needs to be dissipated through evaporation at the skin. Sweat, or additional water applied to the skin, absorbs heat and removes it as it evaporates, helping prevent overheating. The key is keeping this cooling system running efficiently. Hydration plays an important role, but adding more water can also help because water becomes fuel for cooling.
That is exactly how our products work. During a race, they retain water close to the skin, ensuring there is always fuel available for your body’s natural cooling mechanism. They are designed to complement your body's natural cooling process by increasing the active skin surface exposed to water, helping to deliver greater evaporative cooling.
Athletes often combine products across different areas of the body to increase the cooling surface and improve overall cooling efficiency. For example, during a triathlon, athletes use the Glacier TT Cockpit Cooling Kit (including Glacier Tape) to improve cooling in the hands and forearms during the bike leg. During the run, they use the Glacier Hat and Glacier Towel to improve cooling around the head and neck.
The formula is simple:
More surface covered = more controlled evaporation = more heat removed = more cooling watts (a measure of how much excess heat your body is dissipating).
Each use case for our products — before, during, and after training or racing — is identified with an icon in our guidelines and packaging, making it easy to understand the best way to use each product.
