Whakaotihia te rerenga e whai ake nei: I whanau mai i Orlando, Florida, ko Harrison te tuakana o te hoa toa Olympic a Calvin Harrison. Kotahi tau i mua i to rātau whakamātau tuatahi ki te whakauru ki te kapa Olympic, e noho ana te tokorua i roto i to rātau Ford Mustang. Ahakoa ko Calvin te whetū i te kura tuarua, i whakatū i te Tohu Kura Tuarua ā-Motu i roto i te 400 mita, ko Alvin te tangata i whiwhi i te waahi tuatahi o te Olympics i te tau 1996 i te 1996 Olympic Trials. I a ia e eke ana ki te whiringa toa i roto i te 400 mita takitahi, i toia e ia te ara kotahi ka mutu ko ia te tuawha i muri i te mahinga koura a Michael Johnson. Engari i whara a Johnson i a ia e whakatakoto ana i te rekoata o te ao i te 200 mita. I te kore o to rātau toa mētara koura, ā, i te kore hoki o te kaipupuri rekoata o te ao, a Butch Reynolds, ka āhua ngoikore te kapa o Amerika i roto i te whakataetae
4 x 400 mita te rerenga. I titiro te kapa o Ingarangi ki te whai hua ma te kaha ki te arahi, engari i te taha tuarua o te roopu, i riro a Alvin i a Jamie Baulch i runga i te waahi kaainga ki te kawe i a USA ki te arahi, he arahi kaore i mutu te tuku, ka hoatu ki a Alvin he mētara koura.
