The checkpoint food is great! Fruit salad in rice pudding, oranges, soup, hot dogs, golden syrup cake, jam doughnuts, crisps - have to say the penguin biscuits made me heave last year and I have not eaten them since! I carried a large bottle which I kept refilling with water at each checkpoint. You have to take your own cup with you if you want a cup of tea/soup if I recall - I bought a collapsible cup which was very handy.

There is parking near the start however it feels like miles away when you have to walk back to the car after the finish!
