Denmark’s Daniel Jorgensen broke the long jump F42 world record for the second time in eight days with a leap of 6.53 metres at the International Paralympic Committee (IPC) Athletics Grand Prix in Grossesto, Italy.
The 22-year-old European silver medallist first bettered the mark of 6.50m, set by Germany's Wojtek Czyz at Beijing 2008, by one centimetre at a meeting in Leverkusen, Germany, earlier this month.
That record stood for just over a week after Jorgensen added two centimetres to his previous best in the afternoon's find round.
"I am very grateful for this world record,” said Jorgensen, who earlier in the day won his 100m race in 13.29sec.
“It's awesome I've bettered [it by] two centimetres in just a few days.
"The conditions were very good, there was no wind.
“I knew I had that jump in me.”
Strong headwinds during the morning session scuppered any chance of world records over 100m, but a number of world leads were posted during the afternoon session over 400m and 800m.
Mexico's Jorge Gozales Sauceda posted the fastest time this year, 49.21, in the men's 400m T13, as did Great Britain's Paul Blake in the men's T36, 55.41, and Greece's Michail Seitis in the men's T44, 52.96.
The Ukrainian duo of Olena Gliebova and Natalia Iezlovetska also set 2015 world lead times over 400m in the T13 and T20 classes with times of 57.44 seconds and 60.80respectively.
Over 800m, Mexico's Daniela Velasco Maldonado set the fastest time this year, 2min 18.31sec, in the women's T12 class, as did Turkey's Oguz Akbulut in the men's equivalent, 1:57.02.
The day’s action started with multiple 100m races across many classes.
After becoming the world's fastest female Para-athlete earlier this year, South Africa's Ilse Hayes was well outside of her 11.89 world record with a time of 12.42.
So too was home favourite Martina Caironi, May's Allianz Athlete of the Month, after posting 100m and 200m T42 world records last month.
Caironi won her women's T35-42 race in 15.53, while world champion Sophie Hahn was one of three British winners over 100m as she led home a very strong field in the women's T37-38 with a time of 13.40.
The two others were Sophie Kamlish in the women's T43-44, with a time of 14.27, and Ben Rowlings in the men's T33-34, with 18.02.
France's Pierre Fairbank won all three of his races over 100m, 400m and 800m in the T53 class, while Britain's Samantha Kinghorn did the double in the women's 400 and 800m T34/53 events.
Out in the field, Italian Giada Agostini won the women's triple jump T12 with a leap of 7.43m, a national record.
Hungary's Krisztina Kalman registered 13.41m to win the women's club throw F31-32/51, while Malaysia's Abdul Latif won the men’s long jump with a final round leap of 6.98m.
A third round leap of 5.15m was enough for Russia's Kristina Minakova to comfortably win the women's long jump T20, while 5.03m secured victory for Greece's Styliani Smaragdi in the women's F13/35-38/42-47 equivalent.
South Africa's Reinhardt Hamman won the men's javelin F37-38 with a throw of 47.60m and team-mate Tyrone Pillay claimed victory in the men's shot put F41-42 with a throw of 12.71m.
Victories in the triple jump went to Tunisia's Amel Aounia in the women's T20 and Saudi Arabia's Asaad Sharaheli in the men's T20-47.
Men's shot put winners included Ukraine's Roman Danyliuk, who set a 2015 world lead distance, 15.42m, in the F12 class in the F11-13 class.
World record holder Assunta Legante, who holds the Paralympic, world and European titles, claimed another crown with a world leading throw, 14.67m, in the women's F11-13/F20.
The action in Grosseto is due to finish tomorrow.
