Mo Farah broke Dave Moorcroft’s 34-year-old British 3,000m record to underline his form with the Rio Olympics just two months away.
Farah returned to Birmingham a year on from pulling out of the event as doping allegations swirled around his controversial coach Alberto Salazar.
But roared on by a home support untroubled by that storm, he followed the pacemakers through the first 2,000m before hanging on over the last 600m to take a tenth of a second off that long-standing mark.
His seven minutes 32.62 seconds means he now holds the British track records at 1500m, two miles, 3,000m, 5,000m and 10,000m, as well as half-marathon on the road.
The Briton dedicated his victory of his hero Muhammad Ali, the boxing great who died on Saturday.
