No, you don't want heat on this course, not next to the water, to much extra protein. Also runners kick up a hell of a lot of dust on the track at the start.
Albert Kemp is pretty serious about making this an enjoyable and great event for runners and their families and spectators.
The medals are well worth having, they have the course route on them. The cakes are very yum, there's a brass band and plenty of room to crash and chill after the race. There is a clown with lots of activities for children, I think a bouncy castle. The pub serves Harvey's. 
The race is great and very cheap, the route is fun, it's challenging being 15 miles of mixed terrain and undulating. it's def not a PB course as some of the paths\are a bit narrow and there are styles though the big one at the start has been replaced by a gate.
Water and jelly babies are plentiful, as are spnges if you need them.
