Madwa became the first ever Kuwaiti swimmer to qualify for the 2008 Summer Olympics in Beijing within the OIympic cut, competing in the men's 50 m freestyle. He finished under the FINA B-cut (23.12) by exactly a tenth of a second with a blistering 23.02 at the Asian Age Group Championships one year earlier in Jakarta, Indonesia.[3][4] Swimming on the outside in heat eight of the prelims, Madwa smashed the 23-second barrier to take the fourth spot in a personal best of 22.83, but sharing a forty-fifth place tie with two-time Olympian Jevon Atkinson would not be enough to put him further to the semifinals.[5]
