RT: "We will circulate detailed information about the event nearer the time. There is only one planned change to last year’s route on the return between Talgarth and Usk which will divert off to the back road to LLanfoist and then through Chainbridge."
I've had a go at the revised route "between Talgarth and Usk [via] . . . Llanfoist . . . Chainbridge".
https://ridewithgps.com/routes/20922029?beta=falseIt is marginally shorter than going through Abergavenny. I used this route - the revised section from the A40 at Crickhowell to the B4598 heading south to Usk - for the last (dawn) 50km of the 2016 Brevet Cymru. Good quiet roads, significantly so on a May Sunday afternoon when compared with the main roads the BCM routesheet previously guided us down and avoids the major treble roundabout where the (dualled) A40, the dualled A465, and the A4042 sort themselves out (with a B4598 option!).
There is a McDonalds in Llanfoist a few hundred yards off the route.
