After a wild few days of voting in the quarterfinals, we've now reached the semis of our end-of-year Fan Choice competition. Only four fan-submitted achievements of 2013 are left standing, and we'll let you vote on them in just a second.

To find out how we got here, you can take a look at the link above for the original 32 entrants, then see the results from our Round of 16 here. Then, find out how the eight who survived that made it to today with a look back at our quarterfinals.

Some notes from last round, in which more than 51,000 of you cast votes:

-Two of our three remaining individual record achievements faced off, and it resulted in the ouster of our third No. 1 seed and the continued inspired performance of Annie Maria Bissoondial's record. Her No. 6 Most skips in one hour toppled No. 1 Most tennis balls held in the hand by a staggeringly large 74.19-25.81% margin. She's the lowest seed in the final four; 1983 N.C. State anybody?

-The two early heavyweights of the competition passed through: No. 3 Largest swimwear parade on skis continued to catch everyone's eye with its third straight win by 40% or more, while the last remaining No. 1 seed, Largest human waterskiing pyramid, took all it could handle from the kids at Calmore Infant and Junior School with No. 3 Longest human chain to pass through a hula hoop before advancing.

-In our most heated battle of the competition to date, the Largest mobile phone gaming party escaped the Most participants in a touch/mini/tag rugby match. This was a vote that for two of the four days had the two contestants trading places with each other no more than 1% apart from a 50-50 split. Truly a great vote before the gaming party pulled away.

Time now to take a look at our updated bracket (Note: some records may have since been broken from the time they were originally entered into our Fan Choice competition):
