His personal best time was 13.42 seconds, achieved in August 1994 in
Berlin. This is a former Italian record, which in turn belonged to his father
Eddy Ottoz with 13.46 seconds. The Italian record currently belongs to
Emanuele Abate with 13.28 seconds. After this he changed event to the
400 metres hurdles. His personal best time is 48.52 seconds, and in Italy only
Fabrizio Mori and
Alessandro Sibilio has run the distance faster. In 1995, Laurent set the fastest automatically recorded time for the rarely run 200 metres
low hurdles at 22.55. While inferior to the last official world record in the race, a hand timed 21.9 by
Don Styron in 1960, Ottoz bettered the previous best
automatic time 22.63 held by
Colin Jackson, arguably the best hurdler in the world at that time. On 16 May 2010 the English hurdler
Andy Turner set 22.30, but his record was never recognized by International federation, because was obtained in a straight race. Ottoz ran his race around a bend.
IAAF still recognizes Styron as a hand timed record, Turner as the automatically timed record, both for a straight race, and Ottoz as the record holder for around a bend. ==World best performance==
