Edinburgh is in may, but has been organisational chaos last couple of years, not sure about it.Big race atmosphere, but they need to get themselves organised.
Lochaber for a complete change of scene- usually between 1-2 weeks before VLM, less than 500 runners, stunnig scenery, no screaming crowds, nice cup tea and cakes in sports hall after, no travel/ parking problems, flat course- yup, it's my favourite. (scottish weather permitting)
