Three months on and 23 days to go!
I've have refined the revised route:
https://ridewithgps.com/routes/20922029?beta=falseRitchie does not issue a gpx so this is probably as good as a route source (to export a gpx) that riders who depend on electronic navigation aids will get.
Note a 2019 planned change to the recommended route from 2018 is to come off the busy A40 at Crickhowell and go via Gilwern, Govilon, Llanfoist and Llanellen.
BCM 600km audax - exactly as per 2018 routesheet (+ 'south of River Usk' 2019 amdt @546km)

Notes:
1) Follows 2018 route south of Newtown going via Bwlch-y-sarnau getting off 'biker' A483.
2) Includes 2019 planned change (details not yet published) - between Crickhowell and Usk: gets off A40, across the Usk and follow valley to LLanfoist, Llanellen and then across to Usk road (B4598).
Controls at Bronllys (72), LLanidloes (138), Dolgellau (King's 203), Menai (292), Dolgellau (King's 374), Aberhafesp (439) and Llandrindod Wells (492), plus 3 information controls (Machynlleth (170), Harlech (231) and Pen-y-pas (267) (road to Llanberis)
Revised last section: Talgarth, (A479/A40) Crickhowell, (A4077) Gilwern, (B4246) Govilon, Llanfoist, (B4269) Llanellen, cut across river turning onto the B4598 (to Usk) at The Hardwick PH.
There is a McDonalds in Llanfoist a few hundred yards off the route for the desperate, and I guess The Hardwick might attract some for a social afternoon/evening pint.
