The 76-mile route will take in scenic locations along the Jurassic Coast, including Portland Bill, the natural rock arch Durdle Door and the vast shingle expanse of Chesil Beach.
The first Torchbearer of the day will be Tom Mules, 16, from Weymouth, who will run with the Flame at Pulpit Rock, Portland Bill. He was nominated as a Torchbearer for his commitment to competing in biathlons, triathlons and his work as a young ambassador for sport and for children with disabilities.
Vickie Mattock, 39, from Gloucester will carry the Flame to the vantage point overlooking Chesil Beach. She was selected through the Lloyds TSB campaign for her work with local charities.
An evening celebration in Bournemouth will include music from dance troupe Wretch 32, and an electric quintet from the Bournemouth Symphony Orchestra.
The Flame will be carried through 24 communities: Portland Bill, Southwell, Weston, Easton, Portland, Fortuneswell, Weymouth, Preston, Osmington, Winfrith Newburgh, Wool, Corfe Castle, Swanage, Stoborough, Wareham, Sandford, Lytchett Minster, Upton, Hamworthy, Poole, Ashley Cross, Branksome, Wallisdown and Bournemouth.
