it wasn't too bad when on the move Iain; but with the combined freezing cloud & windchill at the top I reckon it would have been around -15- 20 (?). Thankfully it wasn't yesterday, we were around -12 all day ( - 15 in the morning!)
Roads were good, really do-able; although a few sections of Ice Blocks from one side of the road to the other.
Twas a bit of a slog at times, but there was a decent bit of track available
