Using some spreadsheet models I'm trying to plan/forecast my CTL for the season and specifically my key event - 5 day stage race. I've been nailing my plan so far this season continually building CTL 3-5pts week. Now taking a planned 4 day break before starting my event specific training for the stage race in May. So my questions are...When planning for a single peak event what seems to be the best number of days/weeks before the event to peak CTL? Also, any studies/experience on how much to let CTL drop(assuming event specific training continues) when tapering for the event(3%, 5%, 10%)?
