Seriously? The timing of your post would be about right for it to have been me! Blue bike, 2 red panniers on rear, wearing a red hi viz advertising the charity, and (don't tell anyone!) a black plastic hat.
Prior to the summit I would have been standing on the pedals trying to maintain 7 mph and probably shouting and swearing at the wind.
Once round the corner at the summit, the same wind was at my back and I was freewheeling at 25 mph.. But it was brutal heading into it. Now at Aviemore and not got far to go to BoG..
The post for some reason popped up as I posted another post on the A9 west of Perth...
so it would have been at least 30 mins, 45 mins, maybe an hour earlier..but the person we saw was on the what I took to be a path(or old road) at the location, I never noticed any red or panniers though but we'd just been close called by a lorry cutting in on us...I can verify the wind strength as we were getting blown about as we headed south then west.
We (the Mrs) were heading back down from Inverness.....
Keep going, Mr B..
Kudos to you and safe journey north.
Edit :
@Brandane, I checked time I sent an email when I was in Pitlochry and it placed us in the middle of Drumochter at midday...
