The asics great british 10k ? Yep, I am. But you might get a lot of negative feedback from this forum, because of past experiences.
If you haven't run it before, It's a bit chaotic at the start as there are no start time pens, so faster runners can get hampered by slower ones, but if you are just running to enjoy, and anything else timewise is a bonus, then it's a reasonable run. (I have no problems with it !)
