The term trail centre seems to a dirty word on this forum, well in some threads.
Forums are weird places. Post a forum question about trail centres and you'd some time think that would be desserted, an unpopular and unnecessary addition. I was almost shocked that the car parks at trail centers could be full mid week in the winter, more popular in the real world than on here
Trail centres have heavily engineere trails to provide durability. They therefore work well unless covered in ice or snow. any dirt tends to be very thin…..
Mud is very tough for mountain biking. You'll need to learn what trails work in what conditions. From Lancashire you should get to the know the lakes (either the trails centres at Grizedale and Whinlatter or even better the bridleway net work). Although the lakes will be hillier the relative lack of mud may make the trails easier than you local mud fest.
The climbing in trail centres is often on well graed smooth forset trails. Making height gain relatively easy
Any way enjoy your ridding and don't leave the forum…..
