Tried to post this last night but the server was down.
Anyway, I got in touch with the local running club for info about this race on 2.3.03 and this is what they said:
"The Imber Half is quite a tough race as it takes the road from Warminster up onto Salisbury Plain to the now deserted village of Imber.
It is an interesting race as it takes you along a route normally closed to the public as Imber is used for Army training. Because of this the route is only open to runners and marshalls so unfortunately there are no areas for spectators (but surely there must be along the road from Warminster? DD)
Having said all this we normally have in excess of 100 runners,many of whom return year on year as they enjoy the atmosphere (it is a very friendly race!) and to collect another mug which is the runners memento.
This year we have altered the route so that it is circular but in some places it becomes track rather than road.
Sounds very wierd, rather twilight zone (Imber is opened once a year so that old villagers can worship at the church) and absolutely perfect. It should be really easy to meet everyone with that size of field and I'll do some research into a good local pub for afters.
See you there!
