Global Challenge#Specifications of the Challenge 72 one-design

The seeds of the race were sown in Blyth's previous sailing exploits. In 1970/71, he became the first person to sail alone round the world westabout in the yacht British Steel. The practicality of training people who had never sailed before was demonstrated during the 1973/74 Whitbread Around the World race, when Blyth had raced Great Britain II with a crew from the Parachute Regiment. Subsequently, he ran charters for paying crew.

Blyth's longtime associate, Andrew Roberts, forged the design philosophy for the identical yachts used on the Global Challenge races. His idea was to start from the largest top-action production winch available, which would dictate sail area, displacement and size. He also oversaw the build of the two fleets of steel cutters used in the four races to date, to designs by David Thomas and Thanos Condylis (Challenge 67) and Rob Humphreys (Challenge 72).

The first race started in Southampton in September 1992, with 10 identical {{convert|67|ft|m|abbr=on}} boats sailed by a skipper and 13 crew. There were a number of serious rigging screw failures in the Southern Ocean and British Steel II, after the initial success of winning the first leg of the race, was dismasted in mid-Southern Ocean. However, she managed to motor sail safely to Hobart under jury rig. She was re-rigged in time to rejoin the race for the next leg to Cape Town.

The first race winner was John Chittenden and crew in Nuclear Electric. Chittenden went on to win the 2001 Yachtsman of the Year Award.

An expanded fleet of 14 Challenge 67 yachts set out from Southampton in driving rain and gales. Again, rigging problems struck in the Southern Ocean, and Concert was dismasted. Skipper Chris Tibbs and crew made a jury rig and motor sailed to Wellington, New Zealand. Concert was re-rigged in time to start leg 3 from Wellington to Sydney and was 2nd on the Sydney to Cape Town leg. Yacht Pause to Remember, skippered by Tom O'Connor, suffered a snapped boom halfway between Sydney and Cape Town. There seemed no choice but to fly their trysail until crewmembers Graham Phelp and Matthew Reeves took on the challenge of trying to repair it by using a cut out section as a splint. Two days later, a shortened boom emerged from below decks and was successfully attached to the mast. Three weeks later, having suffered several storms with wind over {{convert|50|kn|km/h|abbr=on}}, Pause to Remember sailed into Cape Town, with the boom still intact.

This race featured an extra leg to Boston, and a crew of disabled men and women took part on “Time & Tide,” the first to sail around the world.

Mike Golding dominated, winning five out of six legs in Group 4 with Andy Hindley winning the remaining leg in Save the Children. Three skippers had graduated from being crew volunteers four years earlier: Andy Hindley; Mark Lodge; and Simon Walker, all of whom appeared in the top five placings. Simon Walker went on to become Managing Director of Challenge Business, helping to organise the 2000/1 and 2004/5 Global Challenges.{{cite web|url=http://www.fastcompany.com/magazine/40/wf_walker.html|title=" I Can Only Compete Through My Crew."|work=Fast Company|access-date=2011-05-15|archive-date=2011-04-30|archive-url=https://web.archive.org/web/20110430211402/http://www.fastcompany.com/magazine/40/wf_walker.html|url-status=live}}

On 10 September, a new fleet of {{convert|72|ft|m|abbr=on}} steel cutters debuted in this race. The winner, Conrad Humphreys and crew on LG Flatron, won four of the seven legs.

For the first time, the race was scored on points, with equal points for each leg, though combined elapsed times are shown here for comparison.

The same fleet of {{convert|72|ft|m|abbr=on}} yachts sailed again in the 2004 race, and the winner was the Australian skipper Andy Forbes and his crew on BG SPIRIT, who won three of the seven legs. Once again, although the overall safety record of the race was very good, medical emergencies did unfold, most notably onboard the yacht 'Imagine It. Done.' 'Team Stelmar' (with TWO separate medical evacuations), and 'Save The Children'. In the case of 'Imagine It. Done.' Only an extraordinary, combined effort of several yachts within the fleet, the doctor onboard (Dr Roche), and the efforts of the Westpac Rescue team saved the life of John Masters.Dr David Roche, General Practitioner, East Sussex. UK 'Team Stelmar' suffered both their medical evacuations in the Southern Oceans on the BA – Wellington leg, costing them a {{convert|2,500|nmi|km|adj=on}} detour and 17 more days at sea, making the leg {{convert|9700|nmi|km}} instead of {{convert|6100|nmi|km|abbr=on}} and 52 days at sea. They carried on with 3 crew down crossing the Southern Ocean alone, set the 24-hour record for that leg and finished 11th due to the retirement of 'Imagine It. Done.' Team Stelmar later set the overall 24-hour race record during the penultimate leg of the race between Boston and La Rochelle.

* Retired from leg 2 from Buenos Aires to Wellington (NZ) after a medical emergency on board.

** Stopped racing during leg 2 from Buenos Aires to Wellington (NZ) to render aid after a medical emergency on board the Imagine It. Done.

The current 12-strong race fleet of Challenge 72-footers was developed from the Challenge 67s and was specifically designed to be strong, safe and seaworthy in even the worst conditions and to be self-sufficient for long periods at sea, with enough fuel and water to take their crews safely to a distant port. The yachts were also designed to be relatively easy to sail and handled by unprofessional crews.

The yachts have a snake pit, an unusual feature that allows anyone working the halyards to 'hunker down' and shelter in strong wind and rain, and, more importantly, from waves washing over the deck.

Designed by Rob Humphreys, the identical {{convert|72|ft|m|adj=on}} steel ocean racing yachts were built by Devonport Yachts in the UK by a new method using a unique flat-pack yacht assembly kit of precision cut laser steel panels.
