An estate agent is swapping apartments in Brentford for the flats of northern France next month during a triathlon which will take him from London to Paris.
Justin Stevenson, 31,branch manager of Townends in Chiswick, will compete in the weekend-long event for the Aplastic Anaemia Trust.
The circuit begins at the lido in Hyde Park with a 1km swim in the Serpentine on the morning of Friday, June 20.
Participants then complete a 10km run around the pond before setting off for a final 80km cycle through the countryside and villages of France,ending in Neufmoutiers on the Sunday evening.
Justin told the Chronicle."I'm a little bit nervous about the long bike ride,but the rest I should be fine with."
The married Sunbury resident has been running and cycling since February but is yet to take a dip in the water.
The triathalon was created in 1985 to raise funds for the research and treatment of aplastic anaemia.
Justin wanted to support the cause after losing a close friend to the disease a few years ago, and was spurred into action now after his late friend's sister also began to show signs of the illness.
The annual event is the charity's principle fundraiser and has been designed for both novices and the experienced triathlete, including half endurance options on all disciplines.
Justin will be joined in the full endurance swim, run and cycle option byTim Robinson, the firm's sales manager in Kingston.
