According to the research provided, the 2006 $50k HORSE final table lasted just over 19 hours, with heads-up play lasting a record seven hours and ten minutes between Andy Bloch and Chip Reese.
We are currently at the same length of time for the final table, however we've only been heads up for six hours.
The 2008 WSOPE Main Event final table in London went for a record 22 hours (12pm - 10am).
In terms of number of hands we're currently at 458 hands. We're very close to what we believe is the record that was set at the WSOPE Main Event in London. That event was No Limit Hold'em which traditionally takes longer to play each hand due to bet sizing, deep thought processes, Hollywood'ing, etc.
2006 $50k HORSE - 354 hands
2007 $50k HORSE - 341 hands
2008 $50k HORSE - 314 hands
2008 WSOPE Main Event - 484 hands
