TOO HOT! Live to run another day.
It is Personal Best policy to cancel a training run when relative temperatures exceed 100 degrees. The national weather service has issued a heat advisory from noon today through Wednesday at 7:00 p.m. The heat index is predicted to climb to 104/106 degrees this evening which puts us at a high risk for heat related stress and heat stroke. This is particularly dangerous for those who are participating in strenuous activities like interval training outdoors.
I recommend moving your interval training to Thursday morning or evening as the weather service predicts cooler temperatures. PB speed work sessions will resume next Tuesday, August 30th.
