Laurence competed in the International Paralympic Committee's S9 (freestyle, backstroke and butterfly) SB8 (breaststroke) and SM9 (individual medley) classifications; which is said to consist of swimmers with a severe leg weakness, swimmers with slight coordination problems and swimmers with one limb loss.[3]
McGivern started swimming when he was still in primary school and after a few years his potential was recognised by Paralympics Ireland. He soon joined Newry & Mourne ASC Swimming Club to develop his talent and as his love for the sport grew, he dedicated more and more time to training, and set a goal to one day compete in the Paralympic Games.
He competed at various local and national meets for the first few years of his training, setting and maintaining the current Irish S9 records in all strokes, before eventually qualifying for Senior IPC European and World Swimming championships and even the Commonwealth Games and Paralympic Games.
In 2013 Laurence took Bronze in the 100m backstroke at the 2013 IPC Swimming World Championships in Montréal, Canada. The event saw Ireland's largest ever haul at a Paralympic swimming meet.
McGivern was the fourth fastest qualifier going into the final, having swum a time of 1.06.18 in the heat (close to his previous best of 1:05.35 which he swam at the Paralympic Games in London in 2012, in eighth place). He then went on to swim a personal best time of 1.04.75 in the final, finishing ahead of Paralympic Games bronze medallist Xiaobing Liu of China and Australia's Brenden Hall and claiming his first major international medal.[4]
After just qualifying at the last second for the S9 100m Backstroke, McGivern represented Ireland at the London 2012 Paralympic Games where he ended up making it through to the final.[1] Just scraping the qualifying time of 1.07.83, Laurence smashed this time with a new personal best of 1.05.35 in the heat of the men's S9 100m Backstroke, placing himself sixth going into the final where he finished eighth overall and shocked a few of his more experienced competitors.
McGivern competed in the 2010 Commonwealth Games in Delhi, being the only paralympic athlete representing Northern Ireland in the games. He came seventh in the Paralympic 50m S9 swimming event in a time of 28.95 - he set a personal best of 28.84 in the heats.[5] He also finished fifth in the 100m S10 freestyle final in a time of 1:03.31, being the second fastest of the S9 swimmers.[6]
Laurence's first main international sporting event was at the IPC Swimming European Championships in Reykjavík Iceland in 2009 when he was 18 years old.
This was a great stepping stone on his Paralympic Journey where he had his first experience of elite competition.
