Life

Trubridge was born in Northumberland in northern England, but moved with his family to New Zealand when he was eighteen months old.

As a diver, Trubridge mainly competes in depth disciplines. He has scored the highest number of points for an individual at the Team's World Championships, 313.3, which he achieved at the 2010 Freediving Team's World Championships held in Okinawa, *an.

On 18 January 2011, Trubridge won the World's Absolute Freediver Award (WAFA), as the best all around freediver, with the highest combined score in six freediving disciplines: static apnea, dynamic apnea with fins, dynamic apnea without fins (pool disciplines), constant weight apnea with fins, constant weight without fins, and free immersion (depth disciplines).

Trubridge is an Apnea Academy instructor and as of 2013 operated a freediving school and annual compe*ion, both called Vertical Blue, at Dean's Blue Hole in Long Island, Bahamas from September to May. During the summer he teaches courses in Europe and has trained at the Tenerife Top Training Center.

Trubridge was the main subject of a do*entary en*led "Breathe" directed by Martin Khodabakhshian, which do*ents Trubridge's pursuits in 2010 to become the first free diver ever to reach 300 feet with a single breath in the discipline of constant weight no fins.

On 15 February 2019 Trubridge became the first man to complete an 'underwater crossing' of one of the major channels, swimming across the Cook Strait as a series of 934 breath hold dives. He wore fins and swam with a dolphin kick horizontally underwater at a depth between 3–5 meters, surfacing only for short recoveries during which he remained immobile. The crossing took 9 hours 15 minutes and was done to raise awareness of the plight of New Zealand's Hector's and Māui dolphins, which are both threatened with extinction due predominantly to over-fishing in their ranges.

In the 2021 New Year Honours, Trubridge was appointed a Member of the New Zealand Order of Merit, for services to free diving.
