In reply to euanryan:
Ditto what Offwidth has said about fitness Euan, though you are quite right in that you have to start somewhere.
Unfortunately though I would argue that the SCnL approach is one of the easiest approaches to winter routes in Glencoe, or at least to ones that are reliably in condition. There are plenty of other grade II/III's around which are far less often climbed and less well-known but many of them involve quite long sections of steep, pathless and fairly complicated approach.
Somewhere to bear in mind is Coire nam Beith, though I dare say most would argue it is much worse than SCnL. It is steeper for its whole length, but in my opinion it is an "easier" approach as it gets you there quicker. That's my viewpoint though as someone who runs in these corries several times a week so it probably isn't representative.
Feel free to message me if you want anymore detailed info on conditions in the glen Euan, best wishes.
