A team of Royal Marines ran into Sheffield today to raise money for a vital charity which supports some of their colleagues.
Corporal Will Gingell and Corporal Jamie Thompson hit the steel city as part of their 1,664-mile trek in support of the Royal Marines Charity.
The pair, who were joined by a couple of runners from the Royal Marines Reserves Merseyside unit, started the Sheffield leg at Langsett Reservoir and negotiated B roads through the edge of the Peak District and into the city centre.
There, they set up a marquee and collected donations for the cause.
Cpl Gingell said the Yorkshire landscape was among the best seen so far. Some of the slopes provided challenges for the pair.
"It's good scenery," Cpl Gingell, 33, said.
"There were a couple of hills, but nothing too bad."
The Sheffield run was part of a broader challenge by the pair, who are running 16.64 miles every day for 100 consecutive days.
The pair praised Yorkshire people's generosity in giving to the vital cause.
The charity supports soldiers and their families.
"It's a good charity because it supports the Royal Marines," Cpl Gingell said.
The slow, long runs require plenty of endurance. The pair say recovery each night is the key to staying injury free.
"Stretching, eating and sleeping," Cpl Gingell said.
"And a Yazoo milkshake," Cpl Thompson, 31, said.
The pair train regularly as part of their job, but said the run was getting easier as it went on.
"We're in the swing of it now," Cpl Gingell said.
Their run started in Plymouth, where the pair is based, on April 25.
The pair headed to Bristol yesterday to continue their run. After that, they will head to Cardiff and Bath.
They will finish in London on August 2.
There, they will be presented to Prince Philip, the Duke of Edinburgh.
The challenges are all linked by the number 1664, the year the Marines were formed.
The charity needs £2.5 million every year to continue supporting beneficiaries.
