I registered on the Carten100 website http://www.carten100.co.uk/ a few weeks ago and just received this email. Suggest you do the same if you are doing the ride to ensure you get one of the 1,000(!) places.
Have you Registered for 2013?
For 2013 we are limiting the entry to 1000 riders and the 2013 Entry Form will open on the website on Wednesday 30th January. We plan to thank those who have previously supported the event and have registered with Carten 100 by providing early access to the 2013 Entry Form via a further newsletter on Monday 28th January.
Please note, there will be a new entry system with added features and the ability to pay online. We expect the places to fill up quickly for 2013 so give yourself an advantage! In 2012 the ride filled up in two weeks.
