Am I too old to get to 4w/kg

Training
16

No way. I’m closing on 42 and pretty sure I’ll get to 4 this season, my first solely focusing on cycling coming from a running and triathlon background. Now, we might have genetic limits which prevent us from getting there, but something like 5% of TR users over 40 are over 4W/kg self reported (TR W/kg age buckets). So while age affects it, you’re not too old!
