Ha, I thought i was hardcore.
I may have done the saddlesore once, the ride was close to 1,600Km.
I also may have done more in 36hr but can't confirm.
they should have on for riding even 500km in -7C in my opinion.
I would love to make a dedicated ride to achieving one of these though. Done a few rides around the 1,000 -1,200 Km mark how ever.
I do want to say i'm an IronBut rider.
