Any tubbies travelling with you to Leicester? See if they can compete with Daniel Lambert, a celebrated Leicester lad who weighed in at 52 stone, making him 'the most corpulent man of whom authentic record exists' . Or, you can help yourself on the way to lard land by feasting on the yummy red Leicester cheese or visiting the famous Golden Mile, a strip of superb curry houses.
Try some high-octane motorised activities in the day to burn of those calories with stock car racing, karting and quad biking all being available nearby.
