They are often (but not always) boring if you ride them slowly. They only get really fun when you go really fast. I ride Cwmcarn a lot and I always try to beat my time. I know it really well now which leads to silly speeds and major grin factor.
If you find them dull, get a move on!
This applies to ups and downs. The first climb at Afan can be boring but it makes a good personal time trial if you focus on doing it as fast as possible.
I don't normally say this but +1 kaesae
