Jackson, who recorded 13.14 at a race in Chemnitz in midweek, has not run as fast at this stage of the year since 1993, when he opened with a time of 13.11 and went on to set the world record of 12.91 which he still holds.
Jackson's training partner, Allison Curbishley, also gave herself cause for optimism as she began her preparations for a 400 metres hurdles campaign this season with a 400 metres flat outing, finishing second behind Charity Opara of Nigeria in a time of 51.45.
Britain's European 400 metres champion, Du'aine Ladejo, made a flying start to his career as a decathlete when he led the field at the end of the first day of an international match in Arles, France, on Saturday.
Ladejo mustered 4,162 points as he won three of the first day's five events, his successes coming in the 100m (10.28 seconds), long jump (7.34 metres) and 400m (46.90sec). He also putt the shot 12.06m and high jumped 1.87m.
l Kenya's Elijah Lagat, told five years ago he would die if he did not lose some weight, won the Prague marathon yesterday in a course record of 2hr 8min 52sec. He was told by doctors his life was in jeopardy if he did not lose weight, but subsequently took up marathon running with such effect that he was second fastest man in the world last year.Reuse content
