He saw off the opposition, which included his long-time rival Luke Gunn (Derby), in style.
His winning time, in hot conditions, was a modest 8mins 42.45secs but Wilkinson has run the B standard for the World Championships with 8:28.
He heads the UK rankings and the selectors can use their discretion to pick him in the team for Moscow.
Luke Cutts (Dearne ALC) won the pole vault with a personal best of 5.65m, the second time in a week he has done the B standard.
Crucially, he beat Steve Lewis, fifth in the Olympics, who recorded the same height.
Cutts cleared 5.20, 5.45 and 5.65 at the first attempt which gave him the edge on Lewis. Cutts failed at the A standard of 5.70 which Lewis has cleared indoors and the selectors have the option of picking both men.
Lee Doran (City of Sheffield won the javelin with a modest 70.77m with Joe Dunderdale taking the bronze with 68.38.
Middlesborough’s Chris Tomlinson won the long jump with 8.03m but neither he nor Olympic champion Greg Rutherford have done the very tough A standard of 8.25 and the selectors can only pick one with the B standard.
Annebelle Lewis (Kingston upon Hull) ran superbly to take silver in the women’s 100m (11.43secs) and will have run herself into the relay squad while there were silver medals for City of Sheffield athletes Rick Yates in the 400m hurdles (49.49) and Mukhtar Mohammed in the 800m (1:47.86), the latter narrowly failing to catch Michael Rimmer on the line.
There were bronze medals for Jamie Williamson (Sheffield) in the shot (16.19) Lee Emanuel (Sheffield) in the 1,500m (3:52.34) and Sheffield-based Louise Bloor (Trafford) in the 200m (23.65).
In the 5,000m walk, Leeds duo Jamie Higgins (20:57.15) and Ellie Dooley (24:04.21) both finished third .
Charlene Thomas (Wakefield), coming back to form after injury, was brought down while in a good position along with Laura Weightman in the 1,500m.
It proved the end of Weightman’s race but Thomas managed to get up and carry on but her chance had gone.
Former Leeds athlete Richard Strachan and Richard Buck (City of York) both reached the final of the 400, but could make little impact finishing sixth and eighth respectively.
