Done it before – remember it being tough but looking at your suggestion, you reckon drop down the bottom half of Feed The Pony, along the road and then spin up the old forest road? How long does that take?
It’s not that bad from memory, sub 30 mins on a normal bike at a reasonable pace? It’s fairly mellow until you get through the gate into the trees where its a bit punchy & slick, but that bits not too long & the top is all easily pedalable too.
It is certainly more appealing than going up the push up that runs next FtP. I went up that on an ebike & even on that, it was disgusting.
