- Recognition and treatment of heat illness
- Risks associated with exercising in hot, humid environmental conditions
- The need for gradual acclimatization over a 10 to 14 day period

- Following practice/competition modifications based on the local temperature and relative humidity readings.
In determining safe competition, the air temperature and relative humidity (RH) must be identified and used to determine whether or not practice/competition should be modified, postponed or canceled. There are three different zones:
- Below danger zone
- Danger zone
- Critical zone

Example: 105 deg. F + 35% Relative Humidity = 140 (danger zone)
- Below Danger Zone is (Temp + RH under 135), or if the air temperature is under 105
Practice/Competition as normal
Full pads
Regular running schedule - Danger Zone is (Temp + RH = 136-145), or if the air temperature is 106-110
Practice/Competition with modifications
Reduced amount of equipment
Adjust start times

Water breaks every 10-15 minutes or as needed - Critical Zone is (Temp + RH = 146 and above), or if the air temperature is 111 or above
