Sunday Morning Tuesday Night Ride Club (SMTNRC) 09/10

Nah, the tube's fucked too - I assume it's a shared overground/underground stretch of track being attended to on the day.

Perhaps someone with local knowledge (stb?) can give their opinion on the proposed hike out/back along the A355. What's it like? Hellish? Okay if we ride as a bunch?

That section of the A355 is not ideal. I have not cycled it but it can be pretty fast with swooping bends and I am not sure how wide it is. The long hill down into Amersham does have emergency gravel braking verges though...

It may be nicer to go through Winchmore Hill.
