Well, plans are well under way for this challenge.
I have a team: a colleague from work (raising money for Help for Heroes), a friend from school (raising money for Asthma Research and the Scouts) and my girlfriend will be doing the driving.
We have had two training weekends in the Brecon Beacons and are off to do a main recce of the three mountains and the routes this weekend. Conditions are likely to be a bit different since the main event will be in June (so hopefully some good weather) whereas the Ben is currently covered in snow!

I am planning to do the three peaks challenge some time next year. For anybody not from the UK or not familiar with this - the three peaks challenge involves walking up the highest mountain in Scotland, England and Wales in 24 hours - including all the driving between the peaks.
I think I will probably go for the recommended route and timings:
5pm Climb Ben Nevis
10pm Complete Ben Nevis and Drive to Scafell
5am Climb Scafell Pike
10am Complete Scafell Pike and drive to Snowdonia
1pm Climb Snowdon
5pm Complete Snowdon
