A Poole Harbour start - it's on to Corfe Castle, across to Lulworth Cove, past Durdle Door, with ups and downs all the way to the Weymouth halfway point.
For 100km challengers - it's past Portland Bill, nature reserves, along the western end of Chesil Beach to West Bay's famous cliffs (of TV's Broadchurch fame) - before a finish line celebration in vibrant Bridport.
With Half & Quarter distance options also, with full support and great hospitality all the way - there's a challenge here for everyone!
