The challenge, Row to Santa, saw staff, clients and members of the public take on a portion of the 4234,000 metres from Felixstowe to the North Pole using rowing machines.
Local enrepreneur and gym owner, Mr Matt Brennan urged everyone at the fitness centre to get on a machine and clock up the miles to achieve this mammoth challenge and raise funds for CLIC Sargent.
Mr Brennan said: "We have had over 200 people take part including pupils from Farlingaye High School, army trainers, and members of the public. It was a huge task but we are really proud that we've achieved it!
"The support has been fantastic, everyone has been really motivate to raise as much money as possible to support this brilliant cause."
Mr Brennan even persuaded a group of soldiers from the local Woodbridge base to take on a 24 hour row-a-thon to clock up the extra miles needed to reach the North Pole in time for Christmas.
To promote fitness and help gym members to beat the Christmas bluge, Mr Brennan has now launched a chocolate amnesty in which all donations will go to the patients and families of the Children's Oncology unit at Addenbrooke's Hospital.
Daisy Turner, CLIC Sargent Fundraising Manager for Suffolk said: "We are so grateful to Matt and all those who took part in this unique, festive challenge and for giving up their Christmas treats to support children and young people with cancer."
