RAF officer and Triathlete's World forumite Rachael Cadman made endurance racing history last week by becoming the first woman to complete the Enduroman Arch2Arc Challenge. Only six men have completed the gruelling feat since 2001 - now it was time for the brave 30-year-old to step up to the challenge.
On August 19, Flt Lt Cadman set off on a running, swimming and cycling slog between Marble Arch and the Arc de Triomphe. She ticked off a remorseless 87-mile run from London to Dover, a 22-mile swim across the English Channel and a 181-mile cycle from Calais to the Paris finish line - in an astonishing time of four days, one hour and 42 minutes.
Catch up with the inspiring highlights of Rachael's Arch2Arc adventure with our photo gallery.
