Georgia Hunter of Great Britain, Bell, Dina Asher-Smith and Max Burgin produced impressive performances in the Diamond League final, since they finished their preparations for the World Championship next month.
The trio, each appointed in the British squad for Tokyo earlier this week, reached second place in Zurich with only 16 days until the action leaves in the capital of Japan on September 13.
After having chosen last week to aim at 800m in search of another global podium, the 1500m Bronze medalist, Hunter Bell, ran a better personal moment of a minute 55.96 seconds in that event when he finished runner -up in an exciting end of Switzerland.
That time he transferred Hunter Bell, whose decision to change at 800M could see the line along with the training partner and Olympic champion Koley Hodgkinson in the world final, above Dame Kelly Holmes until the third in the list of all British time.
“It would be amazing [to make the world podium]”, Hunter Bell told BBC World Service Sport.
“I don’t believe two [British] The athletes have a leg on the podium together, maybe Sebastian Coe, Steve Cram or Steve Ovett, so if I and I live, that would be quite special. “
