Prince Harry will visit Bath University this morning to mark 100 days until the Invictus Games.
The Prince will meet injured servicemen and women who are hoping to qualify for the UK team on the first day of the team trials at the university's sports facilities.
The Invictus Games take place in Orlando in May.
During the visit Prince Harry will give a speech to all the competitors wishing them luck.
He will also be meeting and supporting the veterans as they try out on the athletics track and field as well as those practicing for the wheelchair tennis trials.
The Prince has long been involved in the promotion of the event for veterans and is a Patron of the Invictus Games Foundation.
The trials are being run by the charity Help for Heroes, with the support of the Ministry of Defence and the Royal British Legion, over the next three days.
Wounded, injured and sick military personnel are competing across 10 sports to make it into the 100 strong-team for the Invictus Games. The first Invictus Games were held in London in September 2014.
