Not vague at all. I know exactly the route as I did it in 2016 and have done portions almost every year. Not the same kind of up and down hills of the coast, more long drawn out but less grade. Easily done with all those bikes so it is really down to which is most comfortable to ride all day, every day. Let me know if you want any info on it. Kamloops for example, is a pita to negotiate on a bike. It's a scenic route with traffic but good shoulders.
Google maps is funny with it's time estimates. That 2days, 22 hours is a fast total run time which is really a week of so. My usual way points are:
Calgary - Banff - Golden - Revelstoke - Salmon Arm - Kamloops - Merritt - Hope - Lower Mainland.
