My 8 and 10 yo daughters started zwifting this week.
One of the complains my oldest daughter had was that Zwift was changing her jersey to another one that she did not choose. I was a bit perplex that Zwift would do that until I saw it was the green jersey of one of the sprints !!!
W/kg is king, and they are both on the very light side. The results are 3.93 and 3.91 W/kg respectively, and still improving every day they get on the bike. I guess I will now have to train better to improve my 3.1W/kg
