Thought I'd pop in on a comment junior made. He added sleep to his training schedule.
What I thought was unusual is it was just done like an increase in gym time, road time and eating he straight face told me if he did balance increased effort with more rest he wouldn't gain as much. We then talked about ratios which vary depending on activity. For now like 3 in the gym and 4-5 on the bike.
This year for Nats U23 he is cutting out the RR as he can't work the ratios (enough time) to train for it. So we fly in the day before do the ITT, and leave. Maybe crit, depending on schedule but likely too much time.
