The Flame will travel by plane from Southampton Airport to Guernsey.
The first Torchbearer in Guernsey will be Roger Allsopp, 71, who will carry the Flame on the South Esplanade in St Peter Port. Roger was nominated for his Channel swim, which put him in the record books as the oldest person to have completed the crossing.
From Guernsey the Flame flies to Jersey. The first Torchbearer in St Helier will be Richard Collinson, 69, who was nominated for dedicating his life to sport and providing football coaching for young people.
Sal Minty-Gravett, 55, will also carry the Flame in Jersey. Sally was selected for swimming the English Channel on four occasions in four decades and is planning an unprecedented 82-mile double circumnavigation of Jersey Island later this year.
At the end of the day the Flame will return to Southampton airport and will travel by ferry from Gosport to the Historic Dockyard in Portsmouth.
Twelve-year-old Mazie Watson will carry the Flame from the jetty at the Historic Dockyard to HMS Victory, the flagship used by Lord Nelson at the Battle of Trafalgar.
The day ends with an Evening Celebration on Southsea Common. The line-up includes music from dance troupe Rizzle Kicks and a number of local performers.
The Flame will cover a total distance of 48.54 miles on its journey from Southampton to Portsmouth today.
The Flame will be carried through the following communities: Southampton, Guernsey, Jersey, Fareham, Bridgemary, Gosport and Portsmouth.
