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
 
I am still looking for the rest of the team - another couple of walkers and hopefully 2 drivers / support team.
If anyone has any information / advice about completing this challenge with Type 1 diabetes then I would be very interested to hear from them.
More details will be available as and when on my Google site.
