Samantha Fanshawe has something of a natural flair for being a citizen of the planet. She was born to British parents in Peru, and went to school in Pakistan for a few years before the age of 11.

After graduating from the University of Leeds with a joint honors degree in Maths and Biology she took some time out to see the word, including working in Sydney, Australia, before returning to the United Kingdom for two years in business development of corporate clients in the recruitment industry. She was then transferred to Singapore with the same company for a regional management role before moving to Penang in Malaysia and then Hong Kong.

Along the way she mastered the art of dragon boat racing, competing in Dragon Boat World Championships. Sam is an all-around sportswoman, being a runner herself and also enjoys hiking, horse riding and mountain biking. It was while in Asia that she took up running a bit more seriously, starting with more than a dozen half-marathons, and then completing the Singapore Marathon, sprint triathlons, adventure races and ultramarathons such as the Hong Kong Oxfam Trailwalker, Hong Kong 100, the Gobi March and Mongolia Sunrise to Sunset.

Sam's involvement with RacingThePlanet started when she volunteered at the Gobi March 2005 in the Turpan Basin of Xinjiang Autonomous Region of far western China. Despite it being the hottest event on record, she fell in love with the spirit of the RacingThePlanet Ultramarathons and soon came on board as a staff member a few years later.

Sam has been to more than forty RacingThePlanet / 4 Deserts events, in a management capacity during her nearly 15 years with the company. Sam will be the co-race director at RacingThePlanet: Greece 2025.

Carlos Garcia will be the Course Director RacingThePlanet: Greece 2025. Spaniard Carlos Garcia Prieto has worked as the Course Director at more than twenty RacingThePlanet / 4 Deserts ultramarathons and more than a dozen ultra-distance events in total. A qualified architect, Carlos established his own design company after graduating from the Higher Technical School of Architecture at University of Madrid in 1990 with a degree in architecture and has since gained more than 15 years' experience in designing commercial spaces and public architecture.

Carlos' skill and knowledge of course design is an obvious by-product of his experience as both a designer and competitor. He completed his first RacingThePlanet race in 2007 and soon after decided to tackle the 4 Deserts Ultramarathon Series. He is a 4 Deserts Club member, having successfully completed the Atacama Crossing (Chile) 2007, the Gobi March (China) 2007, the Sahara Race (Egypt) 2008 and The Last Desert (Antarctica) 2008. He has also completed the Marathon des Sables, Ultra-Trail du Mont-Blanc, Grand Raid Reunion, RacingThePlanet: Vietnam 2008 and a number of other ultramarathons. A lover of the outdoors and pursuer of sporting challenges, multilingual Carlos has now worked as the Course Director for the Sahara Race (Egypt) in 2009, 2010, 2011 and 2014, The Last Desert (Antarctica) 2012, RacingThePlanet: Australia 2010, Jordan 2012, Iceland 2013, Ecuador 2015, Sri Lanka 2016, Gobi March (Mongolia) 2018, 2023, 2024 and 2025, Georgia 2021 and Lapland 2022. He has also set a number of 100-kilometer courses in the Sahara, Namib and Kalahari Deserts.

Carlos is an active member of the ultramarathon community. He regularly talks on ultrarunning and is a contributing editor for leading sports publications in Spain and Italy. What does this RacingThePlanet enthusiast say he loves most about the races? "In RacingThePlanet races you are never alone. You can run alone, but you will always find someone that will give you a hand."

The 4 Deserts Club member Tony Brammer from Manchester, UK, is a man whose sense of humour is seemingly as great as his determination to finish as far back in the field as possible. The father of two and grandfather only set out to complete one race of the 4 Deserts series. He achieved that aim with the Sahara Race (Egypt) 2005 but carried on through the Atacama Crossing (Chile) 2006, the Gobi March (China) 2007 and The Last Desert (Antarctica) 2008. A company owner and consultant for Brammer Dixon, Tony is a man who sees the funny side of most things. The harder it gets, the more he's likely to call on his sense of humour to see him through. Behind the humour and self-effacing exterior is a man dedicated to helping others. As a 4 Deserts competitor Tony raised money for a children's charity called SAFE at Last, which helps young people who run away from home. Tony is a dedicated 4 Deserts management team volunteer having worked on the volunteer team at more than twenty(!) races since his first time at the Sahara Race (Egypt) 2008. He is again an invaluable management volunteer in the role for checkpoint captain and volunteer manager at RacingThePlanet: Greece 2025.
