In reply to Kimono:
I did it - absolutely full of cold so no legs at all. Managed 6.18 (all-in with some long food stops/rests).
But agree with the comments above - the roads were f'ing awful. I'm sure they weren't that bad last year. One or two places I'd have been nervous at speed on my mountain bike!
Saw one car on the road at about half distance - told a marshall who just shrugged?
Didn't feel as much effort went into it as last year to be honest - no marker signs with distances, top of climbs etc...
Did the Pennines and the Caledonia this year too - the Caledonia was superb but very soft in comparison. Thought the Pennines was silly: too many short steep ups and downs and no chance to get in a Rhythm!
Of all the ones I've done now, I'd say the non-closed-roads Etape Eryri was by far the best. And it goes past my house!
