This is a great in between distance for those progressing from 10k to half marathon, it's also more or less flat the whole way. This was my third time running this course and I think the enjoyment comes mostly from the surroundings which are helped even more by the almost guaranteed good weather at this time of year. Starting and finishing on a lovely Cricket field - you get a real villagy feel - you loop around the back streets of Thames Ditton and up towards Kingston. Further on, running a path alongside the river Thames with Hampton Court grounds on your other side you couldn't ask for a more picturesque route. Friendly marshalls too, who I recognise from previous years.
