I do miss being able to park in the middle, and I know a lot of people basically shuttled so that kids could do the blue without any real climbing. But the tradeoff to that is much more easily accessible trails. The blue and red tasters are about as good a climb to reward rate as you get anywhere, the bigger blue is a wee bit of a trudge for kids up that fireroad though but the descent makes really good use of it. Like, the red “twitcher” is super fast and really throws off all that gradient for jumps and a couple of steepish turns, which is fair enough, but the blue hits a pretty excellent balance between gradient and pedal for the most part and packs a ridiculous amount into it.
(I think that like some of the older stanes XC sections it’d be better with a couple of breaks in tbh, a shelter or two just to give an obvious stop point instead of encouraging people to do it all in one. I think the lay of the land made it impractical to do it in 2 parts with a fireroad to the middle, like say coed y brenin minortaur, but it’d definitely be better if you could do that and make a smaller or larger trail of it as you choose)
