Another mini type ultra that is on the calendar for next year and may interest others is an alternate to the established Bikepacking around Norway dreamed up by Mike at ABR.
It's shorter at 1000km and change, and also partially off road.
Ive heard really good reports about his events in general and the original longer Norway event.
I've signed up for this one along with RATN, and I'll be riding it with my partner. We ride together a fair bit but this will be a step up for her. Im delighted as I don't like being apart for long, and we really enjoy shared adventures.
It looks like there is a reasonable bit of climb and the surfaces will be a bit of an unknown as it's new. It surely can't be as off road as Gravel Tro Breizh. We will treat it as a "try and get to the end" rather than a race and I'll likely load my rig up with most or all of the supplies.
A tent/shelter looks prudent with the remoter sections in the Parks.
