It's a test event for something we're organising outside of Retrobike for next summer. Hopefully it'll identify any glitches and improvements.
Incorporating it with our local christmas ride this year. There will be a modest turnout.
Basically it's based on the Polaris format, but predominantly uses pubs as the checkpoints, hence 'Publaris'. Also off road checkpoints with higher scoring values too though. In theory you could do it on a road bike.
Plenty of bonus points available for solving riddles and drinking certain drinks at certain pubs en route - not all alcoholic though. We'll probably dock points if people try too hard.
We're also toying with the idea of making it a two day event with an overnight beer tent/festival.
