Flying Hot 5K Run
Gustavo and
François went for a 5Km run today in 34C weather. They did it in very fast 28 minutes, cooling down at every lap under a splash pad, and drinking water. Great job, amazing runners.
The secret is to keep your body temperature down.
In hot weather the heart works harder by pumping blood near the skin to cool it down, yet Gustavo's heart rate was normal (as was his speed).
