On September 15, 2007, over a hundred runners wore their running shoes (and left all other apparel behind) to join the annual Patxi Ros nude 5,000 meter race at La Salvaje beach, near Sopelana, Spain. The race was started way back in 1999 when Patxi Ros, a naturist and sportsman, decided to combine his two favourite pastimes in a public event.
For those who intend to join this race next year (nope, not me!), you better start toning your gluteus maximus…and all other muscles for that matter!
