Chris Tomlinson has broken his own British long jump record at a meeting in Bad Langensalza, Germany.
Tomlinson is back in action after suffering a heel injury last month
The 25-year-old set a mark of 8.29m with his fourth-round effort, beating the previous best of 8.27m he set in Florida five years ago.
Tomlinson feels he has even more to come, saying: "I followed up the record with a marginal foul of 8.50m. I only just twitched the plasticine.
"I know I am ready to make the real step up once I get my run-up sorted."
Tomlinson first broke the record in 2002, beating Lynn "the leap" Davies's record of 8.23m that had stood for 34 years.
Despite setting a new mark, the Newham and Essex Beagles athlete did not win the competition, which was claimed by Gable Garenamotse of Botswana.
Tomlinson's coach, Peter Stanley, who worked with triple jump world record-holder Jonathan Edwards, is equally positive, claiming: "I'm certain Chris has more to come."
Only two men have jumped further than 8.40m this year.
Louis Tsatoumas of Greece has jumps of 8.66m and 8.54m at domestic meetings while Panama's Irving Saladino recorded 8.53m in Brazil.
Tomlinson's 8.29m places him equal seventh in the current world rankings.
