Designed for Avenza Maps app on mobile devices, using a couple of different sources. Download a topo map of the Mt Bogong area from Avenza store (eg SV Maps 'Bogong Alpine Area' 1:50k). Save the .txt file to computer & change file extension from .txt to .kml. Email the .kml file to yourself & collect the email on your device. Import the kml contents into the Avenza map using the app's Layers tool (second icon from right at bottom of Avenza UI). Click on individual tracks for pop-up showing run name & length. Contents can be edited in Avenza app or (easier) by importing .kml into Google Earth.
