In reply to fimm:
Scottish Hill Runners is the official website
http://www.scottishhillrunners.uk/Home.aspx however there is also similarily named Scottish Hill Racing
http://www.scottishhillracing.co.uk/Home.aspx
Check out the Races page on the latter, and you'll see a list of all the races that were run in 2017. Those that go up Munros are ( I think ) :-
Stuc a'Chroin
Ben Lomond
Scottish Islands Peak ( Ben More on Mull - you also need a boat and crew for this ! )
Glas Tulaichean Uphill
Slioch Horeshoe
Arrochar Alps
An Teallach
Ben Nevis
Meall nan Tarmachan
Note that the Aonach Mor race does not go to the summit.
There used to be the Glenshee 9, which visited the 9 Munros around Glenshee, but did not run last year. There are probably a few other older races not now running that visited Munro summits.
