Might join you for this one. I am off that week and plan to do Round Scotland 1300. May do them both if the weather permits , Ha , ha .
I would start in Blair at 6pm then join you for a while , as I would then go for a sleep stop at home at 1 am. That spilts it in to 100 and 150 miles for me , Why make it difficult , saves toliet stops and Grumpy Audaxers in Braemar--no names.
I had a go at this a couple of weeks ago same time on a sat night and you wouldn,t want to be any later entring the "Bad lands" of fife . The garage at Halbeath is open 24/7 as the guy said and there is link cash on the outside any how. I used Kevs flatter route in Fife and up the A9 form Aberuthven to Perth at 11.30 ish was quite quiet. But I know you are not all as crazy as me???.
The attempt failed as it was lassshing down when I woke at Dawn.
