Probably the same as the longest ascent but done in reverse. Isn’t that somewhere in West Scotland (or am I thinking of longest continuous road climb/descent)
Golspie still claims the longest trail centre descent, though there is a little pedalling. Other than crossing the forest roads it’s uninterrupted singletrack for 7km.
Carn Ban Mor is a pretty decent descent, 5km long and 800m odd of descent. It does have a 2.5 mile long, steep fireroad climb beforehand. But it’s bloody worth it.
Even though it’s been sanitized.
Also, the Descent from the Ben Damfh ride in Torridon, that is far better than the Golspie descent, and seems a lot longer too…
beeftubs from moffat has 6.4 mile descent one way and ( 3 slight rises and 1 about 800m long) 11.7 mile descent the other way from top of pass. Road descent though although it runs in the hills with plenty of farm paths running beside it so maybe a long descent beside it
Consett to Sunderland isn’t a bad shout though I’m sure I remember a few climbs on it. Alternatively how about the reverse of this, 36.6 km of almost entirely continuous descent. Almost all of it offroad.
By the power of Strava… one of my favourites is 2200ft (670m) of vertical height loss in 2.9 miles which takes about 20 mins, and another recent big one was 1700ft (520m) in 1.7 miles which was over in 12 mins.
I may be imagining it but wasn’t there an article in the mag a while back about a route in the Cambrians which was supposed to include one of the longest singletrack descents in England & Wales?
