Samantha Hunt, 22, from Caerleon, donated £50,000 – half her winnings from the TV game show Deal Or No Deal – toward the building of a school in Kenya, which she went out to help build last summer.
Between 2006 and 2011, she also raised thousands of pounds and helped renovate a rescue centre for street children in Embu, Central Kenya.
Torchbearers were chosen through nomination schemes run by London 2012 and sponsors Samsung, Lloyds TSB and Coca-Cola.
