I notice reading the other postings on this event that a lot of people were not totally satisfied with the event.
Windsor was the race that got me running about 6 years ago, when it was the Building Industry Half Marathon, the company I used to work for ran a coach up there every year and we used to enjoy the hospitality of the parent company, it was always an excellent event. Then a few years ago the organisation changed, it became much more commercial and the entry fee shot up, I have noticed that the same organiser has a few other well established races under his control now.
Although the entry numbers seem to increace (good marketing?) can the event handle the increase? I went up to watch last year and the start was delayed because people were still arriving in droves and queued for the toilets. Personally I now avoid entering any race that is not organised by a running group or club.
