2012 Olympic 4x400m champion and 2010 world indoor gold medallist Chris Brown has been one of the world’s leading one-lap runners for more than 15 years. Here the Bahamian superstar they call 'The Fireman' shares with us one major obstacle he overcame in the early phase of his career.

Much of the attention at the IAAF/BTC World Relays, Bahamas 2015 this weekend (2-3) will be on the Jamaican superstar sprinter Usain Bolt, and the reigning world and Olympic 100m and 200m champion was joined by The Bahamas’s Chris Brown and Great Britain’s Richard Kilty at the traditional pre-event press conference on Friday (1).

This is the event the home crowd will be waiting for, and brings possibly The Bahamas’ one realistic chance of victory.

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.

“Usain, unfortunately he can’t be here, but he sends his regards to everyone and he’s expecting someone to step up and fill his spot.” Those were the words of Yohan Blake, the 2011 world 100m champion, at today’s press conference.

The 4x400m is the traditional closing event for many meetings worldwide, and for good reason. The distance is long enough to be uncomfortable for pure sprinters and draw in some middle-distance runners, short enough to demand total effort above tactics, and tremendously dramatic, even among other relays.

With 36 different countries entering men’s teams in at least one of the five relays at the inaugural IAAF World Relays, picking potential highlights is close to impossible.

Olympic 4x400m champion and world indoor 400m silver medallist Chris Brown will be among the star attractions at this coming weekend’s inaugural IAAF World Relays on home soil in Nassau. The popular Bahamian offers a peek into his life as he answers our work, rest and play questions.

Czech Republic’s reigning European indoor and outdoor 400m champion Pavel Maslak significantly improved upon his fifth position in the 2012 edition, which advertised his arrival as a 400m runner having previously concentrated on 200m, to scorch to in victory 45.24.

The Czech Republic’s Pavel Maslek stamped his authority on the men’s two-lap event with a dominant 45.79 semi-final victory.
