ACCLIMATISATION

Expose yourself to conditions that elevate your core temperature by 1-2°C for 60 to 90 minutes over a period of four to 10 days to ultimately elicit a lower resting core temperature, greater blood plasma volume and an increased sweating rate – all favourable adaptations to exercising in the heat. What if your sportive is hot when the week before has been typical British weather? Then it’s time to buy a fan heater, turbo trainer and get cycling in a bedroom. It sounds parochial but it works.
