If you want to obtain league points you must register. You do not need to register if you just want to race without getting league points.
To register you must complete the form here on the British Cycling website. You must either ride for an affiliated club, or live in Nottinghamshire or Derbyshire to register for the league. League points are not backdated if you take on membership mid-season.
To affiliate your club you need to complete NDCXL Club Affiliation Form 2019.
Please note that when you affiliate to the league, you will firstly receive an order receipt for online payment. At this stage, no payment has been taken and is subject to acceptance by the league. Once accepted, you will receive a second email confirming the application. If a second email is not received within 7 days of the first, this is because your club has not affiliated and paid the club subscription. Please feel free to chase your club.
