It is Corcoran's first major series win in eight seasons on ice and the 2006 Winter Olympian is the first southern hemisphere athlete to win the overall America's Cup title.
Corcoran is now travelling back to New Zealand with her trophy and expects to arrive in Christchurch tomorrow.
The last week of racing had been great preparation for the 2009 World Championship to be held on the same track, Corcoran said on her blogspot on Sunday.
"There are three rather difficult corners/transitions in this track for me [and] in all four of my race runs I got those sections of the track clean with no hits or skids, so my aim of entering the world champs with detailed notes of how to do those sections is achieved,'' she
said.
Corcoran went into the weekend's competition ranked second, having earlier won two of the six-race series.
Several nations sent their top World Cup competitors to the final two races of the America's Cup at Lake Placid to gain experience for the 2009 championships, providing tougher than usual competition at the second-tier event.
Corcoran finished 11th of the 26 competitors but still had enough points from her earlier races to win the trophy outright.
Corcoran said she could not wait to be home after a seven-month season overseas, during which she took just one week off at Christmas to spend with her grandmother in Liverpool.
"I have really felt the length of the season over these last two weeks. I have raced in more races than any other [skeleton racing] athletes, been away from home for longer than any other athlete and probably had more runs than most, too. I am ready for a few days off. My aim was to get as many runs in this year as physically possible and I sure did,'' she said.
Among her other achievements this season was to record a personal best push time of 5.84sec.
She also recorded her best down time and was thrilled to be competing without pain after problems with her shoulders last season.
