Jedward completed the Los Angeles marathon yesterday despite claiming they hadn’t trained at all for the 26-mile run.

John and Edward, who competed in the race dressed in matching stars and stripes kits, revealed that they hadn’t prepared for the event, and had virtually no sleep or food on the day itself.

However, the 20-year-old Irish twins, who last month were selected as Ireland’s entry for the Eurovision Song Contest for the second year running, still somehow managed to finish the course, which went through Hollywood and Beverley Hills before finishing on the West Coast’s Ocean Avenue.

The X-Factor stars later posted several tweets about their achievement in their usual excitable style including: “The swim shorts that we had have now given us baby rash! And we are not babies but now we know what it feels like,” and "We where singing our news songs all the way! finishing the lyrics together and mixing it up (sic).”
