Renaud Lavillenie was the star guest at a European Athletics Championships Zürich 2014 media conference at Letzigrund Stadium on Friday.

Kenya s David Toniok produced a closing burst to claim victory in the 12th Edinburgh Marathon, an.d IAAF Bronze Label Road Race, in 2:15:33 but saw his late chase for the course record come up just short on Sunday (25).

Kenya established a world record of 14:22.22* in the men's 4x1500m final, as Collins Cheboi, Silas Kiplagat, James Magut and Asbel Kiprop turned back challenges from Ethiopia and the USA before simply striding away from everyone else in history.

The first victory of Sunday's program went to the USA as they won the 4x400m title after a loss to Russia at the 2013 IAAF World Championships.

It was a wire-to-wire victory for the USA in the women's 4x800m final, and their 8:01.58 clocking gave them the inaugural event record, a national record, and a symbolic victory over the previously dominant country in middle-distance running.

LaShawn Merritt may have won the 4x400m relay for the USA, but he had to beat 17,004 Bahamians to do it. The USA barely led through the entire race, and Merritt had to come from third place to deliver the 2:57.25 victory.

The US women captured the fifth and last women's relay final at the inaugural IAAF World Relays when they won the 4x200m in 1:29.45. It marked the fourth victory for the USA, who won all the women's relays except the 4x1500m.

The men s 4x100m final was Jamaica's to lose, and they managed to avoid that fate with a 37.77 clocking and an authoritative anchor leg from Yohan "The Beast" Blake. Blake's closing 100m was clocked in 9.07 with a running start.

Kenya became the first gold medallists at the inaugural IAAF World Relays when they took the men s 4x800m final in emphatic fashion, crossing the line in 7:08.40 and taking the US $50,000 first place prize money.

The IAAF World Relays have excelled beyond our expectations
