The best 8-year-old isn’t always the best 12-year-old. The best 12-year-old isn’t always the best 16-year-old. And the best 16-year-old isn’t always the best 21-year-old....Kids all develop differently. Keep encouraging, teach them to compete, & don’t underestimate late bloomers.
@PaulRockieRob Anyone who doesn’t have a lighting bolt next to their name didn’t use a power source. They have a speed/ cadence sensor and Zwift gives them a make believe power called Zpower. It’s the same way in game, if the rider doesn’t have a lighting bolt by their wkg then it’s zpower.
