IN PICTURES: Runners take on endurance challenges along the Northumberland coast.

The Endurancelife Northumberland races consisted of a 10k, a half marathon, a full marathon and an ultra challenge and saw hundreds of runners - and some dogs - travel along the coast to the finish at Bamburgh Castle. Our photographer Jane Coltman caught up with some of them as they set off from Alnwick Castle and Alnmouth.
