Olympic 1500m bronze medallist Hunter-Bell was last with 200m to go but overhauled all of her competitors, including world champion Mary Moraa, with a sensational sprint finish.
Britain’s world indoor champion Amber Anning was third in the women’s 400m in a season’s best of 50.17 seconds, while Dina Asher-Smith ran 10.93 seconds to finish second behind Olympic champion Julien Alfred in the women’s 100m.
Asher-Smith said: “Today was something to ask for, from running in Oslo three days ago, but I travelled well and the body felt good. So to run 10.9 low is really great, and it’s very exciting to be getting so close to my PB.”
British duo Innes Fitzgerald and Hannah Nuttall smashed their personal bests to finish third and fourth respectively in the women’s 3,000m, which was won by Australian Linden Hall.
Fitzgerald, 19, ran 8:32.90 to beat her fastest mark by more than seven seconds, while 27-year-old Nuttall finished in 8:33.82, more than six seconds quicker than her previous best.
Fitzgerald said: “I went into the race with no expectations and I think that is the best way to race. Sometimes I have let the pressure get to me a little bit, but today I was relaxed and I was determined to enjoy it. I absolutely loved every minute of it.
“This gives me so much confidence going forward. It shows where I belong and hopefully I can get into the big championship races.
“I am back to training now as it is a long season. I just want to drop the times in the 5,000m and 3,000m and see where it takes me.”
