When Margo Oakley, now 59, met her older sister's new boyfriend, she had a less-than-favorable impression of the 'po-faced' Mark Blythen, 67. Similarly, Mark found Margo’s 'loud and wild' demeanor challenging. Fast forward over 40 years, the pair became the first in-laws to compete on 'Race Across the World', a BBC show offering a £20,000 cash prize, testing duos without the aid of technology or air travel.
Their decision to enter the race stemmed from a heartfelt promise made to fulfill the last wishes of Julia, who passed away from a rare blood cancer in 2022. Mark met Julia during their student days and described her as 'gregarious and funny', while Margo remembers Julia as the bond that held their fractious relationship together.
In 2019, when Julia fell ill, both Mark and Margo found their dynamic shifting as they supported Julia during her illness, ultimately leading to a newfound friendship.
After Julia’s passing, fulfilling her wish for Mark and Margo to maintain their bond became a poignant motivator. The pair acknowledged the challenge of their past but embraced the adventure ahead, driven by Julia’s memory.
As they traveled to Mongolia, Mark and Margo expressed the mixture of joy and sorrow in their journey, emphasizing that beauty exists in the duality of life. The show is set to air on April 2nd on BBC, promising viewers an emotional and adventurous experience.
