We must remember that success in endurance sport is a multi-faceted area. Similar to motor racing, if it was just the engine it would be simple. It isn’t. It’s engine, suspension, aerodynamics, tyres, hydration, driver skill, mental approach, race tactics etc etc
Time trials aren’t an exercise in going as fast as you can and trying to PB. They are an exercise in being able to practice going fast and thinking about how we perform across the spectrum. How was my skill? What was my mental approach like? What equipment did I use and how did it perform?
