Episode 242 Why am I so Much Slower in the Summer? runDisney Races
In this episode of Running to the Castle, Dr. Ali breaks down why your paces feel so much harder — and slower — when the temperatures climb, using heart rate zones to show exactly what's happening inside your body.
She walks through a simple self-experiment comparing your warm-up heart rate on a comfortable day versus a scorching one, and explains why your heart can't tell the difference between beating fast from sprinting and beating fast from heat stress.
Dr. Ali shares practical strategies for adjusting speed workouts, long runs, and recovery breaks to protect your training through the hottest months.
She wraps up with a hopeful reminder: all that hard summer effort sets you up to run faster once cooler race season arrives.
