The 29-year-old London 2012 champion, who has also won five World Championship titles, added six centimetres to her personal best set in 2013 with the first of her attempts and was in a position to pass on all her subsequent rounds.

Her mark on the second day of action in the Trials moved her up to ninth on the all-time list headed by Galina Chistyakova of Russia’s 1988 world record of 7.52m - which Reese has said is her eventual target - and with Jackie Joyner-Kersee’s 1994 US record of 7.49m in second place.

Reese thus qualified for her third Olympics, having come fifth at Beijing 2008.

The women’s 10,000m final in similarly hot conditions to those endured by the men’s field on the previous day was won by Molly Huddle, who missed out on a bronze medal at last year’s International Association of Athletics Federations’ World Championships in Beijing when she raised her arms at the line, slowing momentarily, and allowed US colleague Emily Infeld to pass her in the final metre.

There was no pre-line celebration for Huddle on this occasion as she crossed in 31min 41.62sec after a powerful drive over the last lap, with Infeld finishing five seconds behind her in 31:46.09.

Marielle Hall claimed the third Rio 2016 place with her time of 31.54.77.

Huddle, who has recovered after missing time in March and April because of a stress fracture, will also seek to qualify in the 5,000m, an event she finished 11th in at London 2012. 

The women’s discus title went to Whitney Ashley, whose best throw of 62.25m came in the fifth round. 

Shelbi Vaughan and Kelsey Card were the two others to earn Olympic spots.
