Hi Rio
I'm probably going to do the Silverstone Half - which I have for the last 3 years - plus maybe the Watford Half - but I may have already missed the deadline, I'll have to check.
The best warm up I did last year was the CWL training day - it was really good, I think about 60 or 70 people turned up. A pep talk, a 20 mile run in Hyde Park and a buffet lunch afterwards.
How about you, what have you got planned?
