Wow, that's alright then! I've never managed Snowdon (no chance of it now either, keep meaning to get the train up some time!).
Some friends of mine were doing the Welsh 3000s a few years back (15 peaks about 3000ft in 24 hours) and I helped run support (mainly lots of cooking for them) but no chance I was going anywhere remotely in an up direction! Shame as it looks beautiful on photos of up there, especially sun up/down.
