Activipedia
The Activipedia is an on-line encyclopaedic reference for York and sport. This is an ever growing resource that is intended to provide articles on specific types of sports, best practice, and anything else that we think that you might find useful.
So just type in a word or phrase that would identify what you might be after and see if you can get any information about it.
If you have information about a particular topic, then why not consider updating one of the existing entries, or adding a new one - any registered member of the site can do it.
