The weather forecast for Sunday is calling for optimal conditions on race day. The race should begin with temperatures in the low 40’s and light winds from the NNW. Humidity will be moderate putting the thermal stress index in the Green flag range. This indicates ideal running conditions.
Keep in mind there is rain forecast for the days prior to the race so if this happens to extend into race day this might increase chances for hypothermia during the race. Cool temperature and wet clothes would create this risk. If this happens wear a top that repels moisture to keep you skin less wet.
Partly cloudy skies should protect most of you from heat stress as the day progresses.
High temperatures are forecasted to be in the upper 50’s. The humidity should drop as the sun gets higher in the sky keeping race conditions in the green flag range. If the sun is not blocked by clouds or if the humidity stays higher (70-95% range) conditions would most likely worsen to yellow or red flag. However, this does not seem likely at this point in time.
Be aware however, if you are developing heat illness symptoms (profuse sweating, fatigue, nausea, headache), the best solution is to slow down to reduce the amount of heat your body is generating. Drinking water or Gatorade will not cool you off. These can help you stay hydrated which helps you dissipate heat but it is more important to reduce the heat you are generating from exercise.
Don’t forget to check your weight in the George R Brown Convention Center before the start. Your body weight is a quick and useful way to estimate your hydration status. The medical team will be in the GRB with scales to help you get your weight. After you successfully complete your run, scales will be just inside the GRB as you walk through Hall A. Also, scales will be at all Medical Aid stations (red pop-up tents). These are located at the Miles: 5, 7, 9, 11, 13, 15, 17, 19-25.
If you have questions before the race, stop the medical information booth in the EXPO near registration or attend presentations by Dr. Chorley or Dr. Cianca at 2:30 PM on Friday, January 15th and noon on Saturday, January 16th. Good luck in the race.
