One unbelievable Aylesbury athlete running seven marathons on seven continents in under seven days

Battling Antarctic winds, Dubai illness, Madrid hills and freezing temperatures in Miami, he crossed every start line determined simply to finish, and did so well inside the cut-off on every continent.

The challenge began in extraordinary fashion in Antarctica, where unpredictable weather created a narrow window for competitors to land, run and depart safely. Participants flew from Cape Town on a cargo aircraft, with organisers keen to ensure everyone was off the ice before conditions deteriorated. The marathon itself consisted of ten 4.2km laps on a triangular course, featuring strong headwinds from the South Pole, steep climbs and churned-up snow underfoot. Several competitors struggled in the extreme cold, and not all were able to complete the race.

From Antarctica, the event moved to Cape Town, where a flat six-lap course along the seafront provided a stark contrast. Despite rising temperatures, it proved to be one of the strongest performances of the week.

The challenge then continued to Perth, Dubai, Madrid, Fortaleza in Brazil and finally Miami. Each location presented vastly different conditions, from intense heat in Australia and the Middle East to cold rain in Spain and tropical humidity in Brazil. In Dubai, a stomach bug affected a number of competitors, testing resilience as much as physical endurance. Madrid’s hilly motor racing circuit placed additional strain on tired legs, while Brazil delivered torrential rain and electrical storms before returning to oppressive humidity.

The final marathon in Miami began late at night and was run in unseasonably cold conditions along South Beach, with reports of record-low temperatures in the city. Despite fatigue, disrupted sleep and the cumulative toll of six previous marathons, the event concluded successfully in the early hours of Friday morning.

In total, 50 athletes completed the full challenge, with many competitors decades younger. The event required not only physical stamina but also the ability to recover quickly between races while travelling long distances across time zones.

The feat has raised significant funds for Thames Valley Air Ambulance, with donations reflecting strong community backing from across Aylesbury and beyond. Support also came from Elite Physical Medicine, who assisted with injury management in the build-up to the event, helping to manage knee and ankle issues during the challenge.

Following his return to the UK, Derek is set to speak at Aylesbury Rugby Club, where he has longstanding links. The club is planning an open evening event for members, supporters and the wider community, providing an opportunity to hear first-hand accounts of the logistical complexity, physical demands and mental resilience required to complete seven marathons on seven continents in seven days.

The event is expected to include a fundraising element to continue support for Thames Valley Air Ambulance, with further details and ticket information to be released via the club’s channels. Organisers hope the evening will not only celebrate an extraordinary achievement but also highlight the importance of community support behind major charitable challenges.
