I learned fast how to keep my head up, 'cause I know I got this side of me that, wants to grab the yoke from the pilot and just fly the whole mess into the sea.
Explainer video on science of why the 400m sprint is considered the most painful track & field event.
And why “no person on the planet can run the 400m all out from start to finish".
The race pushes the way the body creates energy to the limit:
▫️0-50 meters: ATP-CP (energy system for very short and explosive movements; used up after 5-10 seconds)
▫️50-200 meters: Anaerobic glycolysis (burns glucose without oxygen, leading to lactic acid buildup and muscle fatigue)
▫️200-300 meters: Aerobic energy (uses oxygen to break down glucose, but cannot keep up with the demand)
▫️300-400 meters: Anaerobic energy reserves tapped while aerobic energy is too slow to fill the gaps (lactic acid buildup is going HAM)
Track athletes can pace for longer distances and shorter ones are just over quicker (obvs).
The Olympic record is a blazing 43:03, set by South African runner Wayde van Niekerk in 2016 (and 2024 Final race is tomorrow).

This is my daughter Sophie Dennington - I’m so proud of her. She started reffing at 15 years old. She struggled so much in school and at age 13 she had the reading and spelling age of a 7 year old. With the help of her school she managed to pass her GCSE’s. She was diagnosed with Dyslexia but she still got her dream. She’s running the line for the FA Cup Womens Final! A message to all the young ref’s out there. You can do it if you put your mind and heart into something! ❤️

Was a pleasure introducing my kids to the legend that is @leahcwilliamson today, they were buzzing!! The look on Leahs face when she clocked her "favourite teacher" was brilliant 🤣
