In their two seasons on The Amazing Race, Uchenna and Joyce won a total of four legs. In The Amazing Race 7, they won a leg in India, a leg in Turkey and the final leg in Florida. In The Amazing Race: All-Stars, they tied for first place in Poland.
On The Amazing Race 11: All Stars Uchenna and Joyce finished last twice; the first time was on the fifth leg (Mozambique) but they were not eliminated as this was the first of four Pre-Determined Non-Elimination legs so they still in the game. Their penalty however, was being 'Marked For Elimination' which mean't that they would have to finish first on the next leg otherwise they would receive a thirty-minute time penalty. The second time they finished last was on the ninth leg but this was an elimination episode, resulting in their elimination.
Uchenna: (on leg 6 of The Amazing Race 11: All Stars in interview segment) No one will lose any sleep if we're gone, so we know that we have to rely on ourselves.
