British sprinter
David Colin McKenzie  (born 3 September 1970) is a British former track and field  athlete who won the gold medal in the 4 × 400 metres relay  at the 1994 Commonwealth Games  held in Victoria, British Columbia , Canada, along with teammates, Peter Crampton , Adrian Patrick , and Du'aine Ladejo .
McKenzie attended Ingram High School  in Croydon , South London  and trained with Croydon Harriers . On 11 Aug 1985 at Crystal Palace , just one month shy of his fifteenth birthday, he ran a time of 49.97s for the 400 metres, at the time the second-fastest ever time for an under-15 athlete, and as at 2008 was still the third-fastest time.
He reached his all-time peak on 12 June 1994 when he ran 45.47s at Sheffield for Shaftesbury Barnet Harriers .[ 1]   This earned him a solid place in the England  team for the 1994 Commonwealth Games  in Victoria, British Columbia . At those games he was part of the 4 × 400 metres relay team that took gold (along with Peter Crampton , Adrian Patrick , and Du'aine Ladejo  with Mark Smith  and Alex Fugallo  in earlier rounds).[ 2] [ 3] [ 4]  
McKenzie also won a relay gold medal in the 1994 Helsinki European Championship  4 × 400 metres relay team alongside Brian Whittle , Roger Black  and Du'aine Ladejo . McKenzie was to also feature in the season ending World Cup  at Crystal Palace  again winning gold in the 4 × 400 metres relay  with teammates Du'aine Ladejo , Jamie Baulch  and Roger Black .
He finished third behind Kennedy Ochieng  and Ade Mafe  at the 1993 AAA Championships .[ 5] [ 6]
