Welsh brothers Scott and Rhys Thomas recently completed a charity run across 13 states in the US –the equivalent of 74 back-to-back marathons–for 70 days.
On September 15, the brothers left from Boston, Massachusetts, finally arriving in Austin, Texas, on November 26, with the full journey of about 2,000 miles.
Scott, who celebrated his 30th birthday in Ohio and has lost 24lb, said, "It was exhausting. Mentally and physically exhausting, trying to move yourself each day. But it has been quite a fulfilling achievement to finish."
The brothers had been training for a year for the challenge. Scott said they had planned to run a marathon 26 miles each miles they were putting in.
The brothers have run 35 miles most days, jogging for five-to-six miles then stopping for a water break before repeating this throughout the day.
Scott said the pair had been burning up to 6,000 calories a day but had not always been able to find it, so had lost a lot of weight. The brothers hope to raise ￡250,000 （about＄390,000）for charity.
Scott said: "I just tried to keep determined. That is one of the things that kept me going is thinking of other people that we've been trying to help."
