AILBHE KELLY (S8 400 metres freestyle, heats 2.09pm. Final 21.59pm)
In her first Paralympics, the Castleknock teenager, who turns 18 during the Paralympics, begins the first of three events and has the honour of being Ireland's first representative in action at the Games. Her personal best in the 40 metres freestyle is 5.35.49, set this year. Her world ranking is 17, her European six. The standout swimmers are Australia's Lakeisha Patterson, Stephanie Millward (GB) and Jessica Long from the USA. A new personal best would be a great effort.
GRETA STREIMIKYTE (T13, 1500 metres, heats 15.30pm)
Born in Lithuania, Greta, one of triplets came to Ireland five years ago and finally realised her dream when claiming an Irish passport this year that allowed the student to fulfil an ambition of competing in the Paralympics. She represented Ireland for the first time in the Europeans where she won a bronze. Her PB is 4.48.85, enough for a world ranking of fourth. The absence of the Russians won’t hurt and if she runs close to her best, the girl with Stargardt’s disease (some vision in her left eye) could medal.
JAMES SCULLY (S5/SB4/SM5 200m freestyle heats, 3.31pm, Final 23.59)
In his second Paralympics, this represents his strongest event. He is the only male, blessed amongst women in the swimming team. His personal best is 2.53.03, his seasonal high point, 2.54.76, giving him a world ranking of seventh. Daniel Diaz from Brazil is the favourite. He goes in lane three of heat one and is fancied to make the final, which takes place at 23.59.
DAMIEN VEREKER/SEAN HAHESSY (Individual Tandem 4K Pursuit , heats 3.45pm. Final 21.38pm)
It is the first International Paralympic first event for the two of them, having come together from different tandem pairs earlier this year, their only event a World Cup race in Bilbao. A top eight finish would be is the challenge although the Kilkenny/Tipperary axis are talking about a medal opportunity if they can manage a time of 4.16 or thereabouts: GB, The Netherlands, Germany and Spain are the form outfits.
SEAN BALDWIN (10m Air Rifle, SH1, qualifying 4.0pm, Final 18.30pm)
The Kildare native who lost a leg in a car accident while on duty with the Irish Defence Forces in Liberia (2003) is competing in his second Paralympics.

The last time Ireland played the Ukraine they lost 7-0. Luke Evans captains an Ireland side that includes several players who play Leinster Senior League soccer. The players are have some degree of Cerebral Palsy. The IPC has removed 7-a-side football from the programme in Tokyo 2020.
JASON SMYTH (100-metres, T 13 Heats, 23.19)
The world number one is going for a third straight Paralympic gold medal in the 100-metres having done so in Beijing and London, on each occasion breaking the world record in the final. Twice an Paralympic 200-metre champion that category has been removed from the programme so this is his sole event. Brazilian Gustavo Araujo is ranked second in the world, Australian Chad Perris third but if Smyth runs close to his season's best, 10.39, no one show prevent him from confirming his mantle as the Fastest Paralympian on the Planet. The final is on Friday.
