Dave,
You only need a mapping package like OCAD if you are a mapper and want to draw your own maps, or edit other people's maps. Otherwise whoever has the original map file should be able to export a KMZ file needed for MapRun for you.
OCAD is the premium professional mapping package but there are others like Open Orienteering Mapper. Also you can get auto generated maps, mainly for StreetO, from www.oomap.co.uk.
For a summary of options to produce a KMZ file for MapRun see:
http://maprunners.weebly.com/maps---kmz-files.htmlIf you are looking at OCAD, it comes in different variants (as you have listed), and a new version number is released every year or so. The current version of each of the variants is "OCAD 2020" and geo-referencing has been supported since around version 10. (they changed from versioning like 8,9,10,11 to 2018, 2019, ...).
