I think the key bit here revolves around the section with the two black cruxes. The easy one is a steepish cobbled but swoop easy short downhill with a two red chicken chutes on the left. It drops down to the leet. Shortly after that the red drops off left to the proper black crux. It’s about 123 times harder than anything else on the black, a little rocky outcrop with an easier off balance line on the left and a full on line straight over. Before I get flamed by all the degla haters, I need to emphasise that this is only hard in comparison to the rest of llandegla. AGAIN; THIS SECOND CRUX IS AVOIDED By most people on the left. (Scuse caps)
Anyway, hopefully you know the bit of trail I’m thinking of. The blue trail peels off near(or even in between) these two black bits.
But the whole point of what I’m going to say is that this whole little section is bypassed by a bit of single track that traverses in from underneath after the b line. So if you do the b line then you’ll only glimpse it from below. The solution is to take the fire road all the way up after the b line rather than the single track up hill. Then somewhere amongst the 2 black cruxes you’ll find the blue escape.
It’s a bit weird that doing one bit of black means you miss the next bit… but ho hum
HTH
