Triples are , or can be set up like a single ,

the other 2 chainrings take over for when high is just not high enough,

and Low you need a few more gears.. It has worked for Millions of touring cyclists..


make out a gear ratio chart, using one of the online aides like "sheldon gears"

Another option .. hybrid rear hub .. 3 speeds in the hub, and diver that takes cassettes .

then the functions of a triple are all internal , and downshifting bat a slow speed on a Hill can happen

IGH can Shift while stopped too..
