His marathon personal record of 2:10:40 from New York[9] prompted Boston news organizations and Runner's World to regard him as one of the fastest runners in the world.[6] When he began winning U.S. road races, he was part of a cultural shift that saw top prizes going to foreign runners (often in Kenyan and Ethiopian).[10] These sweeping wins prompted many race officials and running commentators in the early to mid-1990s to suggest ways to distribute prize money not just to the first-place finishers (who were often African), but also first-place American finishers.[11]
The peak of his marathon career was 1996-1997. In April of '96, he made his 26.2-mile debut battling on the roads from Hopkinton, Massachusetts, to Boston with the top runners in the world. At the halfway mark, Kamau was leading the rest, clocking 1:02:01. But two miles later he was in fifth, and he finished in 30th (2:18:48) while Moses Tanui took the win in the 100th running of the race.[12]
In November, he toed the line in the New York City Marathon on a morning with 40-degree weather and gusting wind, dueling with Tanui, Cosmas Ndeti, Turbo Tumo, Andres Espinosa, and other elites from around the world. This time, Kamau didn't fade late, but led with Tumo and surprise contender Giacomo Leone, a police officer from small-town Italy. As Leone dropped a 4:44 mile at marker 25, Tumo got a step on Kamau, who kept the pressure on to earn $25,000 in a third-place finish, just 15 seconds ahead of fellow Kenyan John Kagwe. (Kagwe would go on to be the '97 and '98 New York City Marathon champion).[13][14][15][5]
At the 1997 Boston Marathon, Kamau had a better idea of the course's punishing Newton hills and didn't take the lead until the halfway point, which he crossed in 1:06:11. As he moved through Brookline, Massachusetts toward the city, he traded places with Dionicio Ceron, Andre Ramos and Lameck Aguta. But into the city, Aguta passed them all and Kamau held strong on his heels. Kamau finished second in 2:10:46, just 12 seconds behind the winner. After the race, Kamau told reporters he favored the shorter distances.[16][17]
He is the course record holder for the Crim Festival of Races 10-mile, where he won in 1996 on a cool day. He had placed second the year before (to Thomas Osano) when they had both broken the previous record time. Kamau's 1996 win came within six seconds of breaking the world's record 10-mile time.[22][23] He was fourth at 2002 the South American Marathon Championships, where he ran as a guest.[24]
He is a two-time winner of the Philadelphia Distance Run (1995, 1996)[25] and a three-time winner of the Long Beach Marathon (2001–3).[26] He debuted his full marathon running skills at the Frankfurt Marathon. He has continued to receive recognition for his fast race times over the years.
