Walking is one of the most popular pastimes in the UK - apparently 77% of adults (38m people) say that they walk for pleasure at least once a month - and, I guess, it's got more popular recently given that it's free and times are tough. I'm sure lots of people will tell you to take energy bars, water bottles, apples, blah blah blah.
I didn't read any advice on this before undertaking any of the c12 mile legs of The Test Way. Instead I experimented for myself and, I'm pleased to say, I have the solution:
Jaffa Cakes, apples and water.
On Leg 1 I think we took a big bar of Dairy Milk, a bag of apples and some water. By Leg 3 this had grown to include a bag of Cadbury's Chocolate Eclairs and a packet of Hobnobs.... clearly getting less and less healthy as time goes by!
By Leg 4 I think I had perfected it. The Eclairs had been a little too much and all that grub added to the weight in the ruck sack. So now we had, between the three of us: six apples, three litres of water and two packets of Jaffa Cakes.
I don't know if this is the optimum processed/natural sugar to hydration ratio, but it worked for me!
