Also, if you are in Cornwall and want to explore some routes on your mountan bike, have a look at Kernow Adventure. You might as well learn to love this rainy weather and bring out your inner child - charge down those muddy lanes and get covered, it's fun! (Honest!).
Finally, I have to share this link with you for a fantastic Velodrome cake (See below). Of course you can only eat it, once you have been on your epic bike ride!
