Many riders seek climbing ability, however, your ability to climb comes down, very simply, to your FTP and your weight. Maximize your FTP (through TrainerRoad training plans) and optimize your weight, and you will become a faster climber.
All TrainerRoad Training Plans will make you a faster climber (by improving your FTP). But when it comes to choosing a training plan, you need to ask yourself “What kind of climbs do I want to be good at?”.
The Crit Plan and associated foundation plans make you very good at climbing 1-3 minute hills, very very hard.
The Rolling Road Race and associated foundation plans would make you very good at climbing 5-15 minute climbs at a high pace.
The Climbing Road Race and associated foundation plans will make you very good at climbing 30-90 minute climbs at a high pace.
The Century Plan and associated foundation plans will make you very good at climbing all day at a sustained pace.
Since you will be visiting Salt Lake for a riding vacation rather than a race or series of races, the
Sweet Spot Base -> Sustained/General Power Build -> Century Plan
will be your best bet for a great trip.
I hope this gives you a bit of context for selecting your training plans! I know it’s a long ways off but I hope you have an awesome trip! Salt Lake City is an awesome place to ride a bike. I’ve ridden from Salt Lake to Park City up little cottonwood canyon and it’s a beautiful (and brutal) climb.
