If preparing to ride in high heat for a prolonged period of time, a cyclist should build up slowly, by initially limiting workouts to one hour or less, train during the cooler parts of the day and always hydrate. The athlete can then increase training load. In hot temperatures, take ...NIST fire analysis tools featured in online training
