RW charge both organisers and entrance a percentage of the entry fee for using their online system. The organisers might have decided it wasn't worth it. It is a pity there is no basic list of events, such as you find at the back of the magazine
It's possible to create an event without using RW's online entry system, in which case there's no charge. Even if the search result comes up as "subscriber content only" at least people are made aware of the race's existence. From what I recall, the full listing becomes available closer to the date of the race, including details of how to enter, externally to the RW site. (For example, Kent AC's Sidcup 10, March 10th next year!
) But it's up to the organiser to add an event, rather than RW to provide a comprehensive list. Perhaps the organisers of the Cabbage Patch 10 don't feel the need to publicise it any further than it is already. 1,500+ finishers is quite an impressive field. Great race, definitely considering coming back next year.
