Ah but of course if you start competing there is the obligatory bacon butty at some god forsaken hour of the morning after walking that impossible course! (or egg obviously for vegetarians!)
Followed by the oh so healthy burger from the burger van and then if camping the copiuous amounts of alcohol and snacks at the various awning parties around the site.
No but seriously - that is great to hear - so added bonus - having a fantastic time, building a great partnership and team with your dog and losing weight!! Congratulations!!
