Tomorrow's penultimate Diamond League meeting of the season in Rome's Stadio Olimpico offers Armand Duplantis and Karsten Warholm one of their last likely opportunities in 2020 of attaining the new world record marks to which they have come so tantalisingly close in recent months.

Duplantis, who raised the world pole vault record to 6.17 and then 6.18 metres earlier this year at indoor meetings in Toruń and Glasgow, has since had a total of 13 attempts, spanning five meetings, to clear 6.15m in the open air.

That would be the highest ever jump outdoors, surpassing the 6.14m achieved by Sergey Bubka in 1994.

If the 20-year-old US-based Swede has need of competition to propel him to such heights it will be offered in the form of France's 33-year-old former world record holder Renaud Lavillenie, who cleared a season's best of 5.80m to win the French title last weekend.

Harry Coppell, who vaulted 5.85m to win the British title earlier this month, and the rising talent of Ernest Obiena of The Philippines, who had a breakthrough victory at the Continental Tour Gold meeting in Ostrava last week, will also be challengers.

Meanwhile Warholm, Norway's double world 400 metres hurdles champion, has pressed ever harder towards Kevin Young's world record of 46.78sec, set in winning the 1992 Barcelona Olympic title.

Had he not hit the final hurdle during his run at the Diamond League meeting in Stockholm last month, that record may have been his.

As it was his reward was a personal best of 46.87, and since then he has maintained an awesome sequence of winning times.

The most recent of these came on Sunday (September 13) in Berlin, where despite swirling wind at the ISTAF Continental Tour Silver meeting he clocked 47.08.

Despite the best efforts of the organisers of an event that was originally scheduled to take place earlier this year in Naples while the Stadio Olimpico underwent building work – before the COVID-19 pandemic intervened – no spectators will be allowed because of health restrictions.

The Golden Gala Pietro Mennea will see the return of Jamaica's Rio 2016 100 and 200m champion Elaine Thompson-Herah to international competition this year.

Thompson-Herah clocked 10.88 over 100m in Kingston in June and a wind-assisted 10.73 in July.

Her closest rival is likely to be Switzerland's Ajla Del Ponte, who has run 11.08 this year.

In the men's 100m, home eyes will be on 22-year-old Filippo Tortu, who holds the Italian record of 9.99 and clocked 10.07 at yesterday's meeting in Bellinzona, Switzerland.

The women's 800m promises a fiercely competitive meeting between Scottish training partners.

Jemma Reekie, unbeaten this season over two laps and with a 2020 world-leading time of 1min 58.63sec, faces European 1500 metres champion Laura Muir, whose 800m best this season is 1:58.84 and who set the fastest 1500m time of 3:57.40 in winning in Berlin on Sunday.

The sole distance event on the programme, the men's 3,000m, features two prodigiously talented 19-year-olds in Norway's European 1500 and 5,000m champion Jakob Ingebrigtsen, who set a European 1500m record of 3:28.68 last month, and Uganda's Jacob Kiplimo, who won the 5,000m in Ostrava in 12:48.63 last week, the third fastest time recorded this year.

Also in the mix will be Australia's Stewart McSweyn, who finished 30m clear of the field in winning yesterday’s 1500m at the Continental Tour Gold meeting in Zagreb in 3:32.17.

Ukrainians Yaroslava Mahuchikh and Yuliya Levchenko, the only women to have cleared 2.00 metres in the high jump this season, will resume their domestic battle in company with Australia's Nicola McDermott, who set a personal best of 1.98m last month.

In the men's high jump European indoor champion Gianmarco Tamberi, who has cleared 2.30m this year, will be seeking to register a home win against a field that also includes Ukraine's Andriey Protsenko, who has also registered 2.30m this year.

The final Diamond League meeting of the season is scheduled to take place on September 25 in Doha's Khalifa Stadium, which hosted last year's World Championships.
