Are there any sports other than Test Cricket played over the course of five days to achieve a result? Even in Cricket, the match may end in a draw, which means no result is obtained. But, is there any sport available, that takes as long to play and achieves a result at the end?
In tennis, John Isner defeated Nicholas Mahut 6–4, 3–6, 6–7(7–9), 7–6(7–3), 70–68 in the first round of the 2010 Wimbledon Championships after 11 hours 5 minutes, played over three days.(1)
Please note that this is an extremely rare corner case, but fits the definition of "played too long to achieve result."
