@toomanybikes - I only have his provisional route. He asked me not to share it has he was re-riding it last weekend and was going to make changes.
it was basically this:
its a brutal 153km, with 1,750 of climbing. I reckon by chopping off the loop top right so following the river from east of Melrose and rejoining in Dryburgh saves 35km, and chopping the bottom left loop saves 13km and a big hill.
Two biggest climbs are either side of Selkirk & in and out of Jedburgh.
not for the faint hearted I would assume. want to do end of month, need wingman/person...........
