Welcome Danny,
i'm a Dentonian and have a few contacts/friends from the Oldham area. If you can tackle your neck of the wood, you're on track for some great fitness rides! Saddleworth, Greenfield, Holmfirth, Dovestones, Uppermill are to name a few. All of which are on your doorstep. Some great rides for you to enjoy. Just make sure you are on the ball with your brakes though. Don't let them whittle down too low before acting on it. :-)
