I'm thinking of doing the Scottish 4000s next year, a challenge I've been promising myself to do for years. The idea is to start at Fort William and do the Lochaber 4s and the cycle up to do the Cairgorm ones then bike back to FW. I know that Martin Stone used to organise a challenge event/race, anyone else done it or any ideas on logistics, distances etc. going to be fun planning methinks.
