Sorry, but get really p1$$3d off with the negativity on here at times!
If its your first tome out in 15 years then i dare say you are looking forward to going to Gisburn tomorrow! And so you should be – you will have a great time!
Sure, once you have done a lot of riding then maybe you will think it comparably less exciting or challenging than other places but i reckon you will enjoy it!
Its quite hard work on the uphill sections especially if bike fitness is a little lacking. As Dales_Rider said, some of the best bits are off the main fire road so keep your eyes peeled so you dont miss them. Also (according to some) the Hully Gully is in a poor state towards the bottom so watch out for that.
Have a good one!
