But, how would you actually carry it for extending hiking periods! Well, this popped up (courtesy of the Restrap HT550 email) which shows this chap (assumingly not a model and supposedly in the HT550 of some sort (probably not a group start!?) and they actually have ingenious ways of carrying the bike that doesn't look as complex!
Anyone any exp of doing a similar thing. Assume it's uncomfortable or specially made/intended for bike-hike duties? The other carrying is through the Grand Canyon where I saw a shot of Lael W doing such a thing. But that's a wheels off and properly strapped type thing, so maybe a specially adapted ruck/bikepack!

For ref the NorthWales route goes via Snodonia (forgotten the proper name, soz) and the mountain range walkers/bikers rules would be followed. But if one was to say, carey the bike on the back. Would that make one a walker and not biker/biking, so shared path rules would be fine during day too?? I assume the answers no?
