He was completing the four lists mentioned on the same day (23/5/09), the first three as a single walk up Corrour way, the Donald (Blairdenon) separately. An impressive achievement - if perhaps akin to eating several dinners at once! There have been a few remarkable things like this over the years - Brian Ringland finished Munros, Munro Tops, Corbetts and Grahams on the same day (2/6/04, Sgritheall etc) on foot as part of the same walk, and Roderick Manson managed Munros, Corbetts and Grahams on the same day (17/6/06, Seana Bhraigh etc) during a coast to coast walk. Most I know of is (almost inevitably) by Rob Woodall who finished five lists in one day (6/10/02), although some of these were less well known lists than the ones mentioned above.
Incidentally, re the thing of taking map and compass on the hill, while I'll almost always do it on something Corbett or Munro size and also on any new hill or something climbed from a new direction, it depends on whether I've been there a lot before. Even in poor weather I'm about as likely to take map/compass on some standard local-patch loop from the southern side of the Ochils as I am to take them with me when heading out to the shops. Not likely to be much needed either if doing, say, the standard path circuit of Ben Lomond from Rowadennan in summer (although I'd almost certainly take them for that if only out of habit).
