It looks very difficult, wondering if anyone on here has done it

Look like about half the route of the ill fated Gran Fondo Cymru. The climb over to Dinas Mawddwy is scenic, and Bwlch y Groes is a good pull, you just need to pace yourself right and enjoy it.

thanks
the cut-off timings look a little daunting but I’ve got 8 months to train for it

Yet another sportive using inaccurate software and publishing climbing figures.
I’d put lots of money on that route being way less than 3200m.

Bwlch y Groes is tough, no doubt about that but has very little else to it & I don’t fancy riding on the A470.

Just seen the “Big Dog” with 4000m of “pluck a figure from thin air” climbing.

I shall think about this event as I’m dancing on the pedals up the Giau in early July on my way round the Maratona 😉

I’d rather be sat in a cafe watching the Maratona go past !
