Yep - got my number today, and queried the chip as the web site said something clearly different. LEAVE THE CHIP ON YOUR NUMBER.
Got to say, some of the administration aspects have been poor, but souldn't take any shine off the day. I've been to several races allowing collection on the day, and its never been a problem (provided its organised and staffed sufficiently)
Currently 85% sure I will be running tomorrow. Managed a few miles over the last couple of days, and currenty 'testing' the best way of strapping some 'running issues'. If not it will be Abingdon next week.
