Two weeks ago on a rainy Saturday I rode over to the official opening of the Tynehead Perimeter Trail Opening, From the picture you can tell it was wet as I had the roof on the whole time.
The trail around Tynehead Park is marvelious. Five kilometers of very smooth payment and no cars to worry about. Mind you should be carefull around pedestrians and slower cyclists. This is one of the bigger green spaces in Surrey and will offer a nice change from riding with cars especialy when the greenways connecting it are all finished. For more info on all this go to this map for a map of the routes.
