More than 3000 kilometres, 131 days, two brothers and one epic journey along the Great Wall of China.
British Chinese siblings - James and Thomas Lindesay - spent 6 months running and walking along the main west to east length of the wall - starting in the desert all the way to where the structure meets the sea - near North Korea.
They've been literally following in their father's footsteps - William Lindesay who made the same journey in 1987.
