Steve,
Welcome to APAT.
Good luck with trying to get seats for the World Champs at DTD, as for the event at Luton this year, it is the European Champs. The team event is held on the Thursday and Friday with the individual main event (200 runners) on the Saturday and Sunday. The main event has not yet been released for sale. Satellites will run on Blue Square, before the remaining tickets are sold from the apat homepage.
Keep an eye on the forum for updates.
