Terry Owens and his sons, Ben and David, are doing a coast to coast walk from St. Bees in Cumbria to Redcar in Teesside. Between them they weigh over 50 stone and are all prone to eating (and drinking) a tad too much and not exercising enough.
They are assisted by Terry's wife Gill and Ben's Girlfriend Amanda (and their kids - Louis  and Charlotte [10 months])
They've never undertaken anything like this before - its going to be an interesting fortnight.
