Nobody is encouraging anyone to do anything dangerous.
There have been, perhaps, three days in the last month when the entire country was ice or snow bound. There are now large tracts of landscape (mostly near the south coast - but there's plenty even here in East Anglia) that are snow and ice free, or at least, have completely clear A and B roads. Aren't we supposed to be resourceful? We're happy to duct-tape our bikes together in order to complete a ride, but not prepared to get on a train and go somewhere where it's safe to ride?
It is quite possible to ride a safe, A/B road 200, right now.
So at best, this move is premature - after all, we're not even half way through the month. Personally, I think it's completely unnecessary, and somewhat counter to the nature of audax. I see nothing "audacious" about staying at home, when there are (safe) alternatives.
Right, I too am back in my box.
Edit: However.... I'm mindful of the fact that I've posted this in the AAA Round The Year thread. I could be persuaded that ARRTY might be currently inadvisable on account of the state of upland roads, and their remoteness. But the same doesn't go for RRTY.
