Well, for me anyway. This is the best episode of Record Breakers ever. Not just in this series but in the whole catalogue over many years. The highlight of this show is the race with John Walker running backwards competing against the super fit host Roy Castle, running in the normal forward facing direction. I won't say who won as that would be a terrible spoiler. I wish I could find this clip somewhere on the internet. I say all this with such confidence, but really it is only from memory seeing this episode air in 1979 and not at all since. Record Breakers was a staple kids TV show that adults also loved to watch. Quite a rarity.
