He returned to action in 1983, although once again his season had been hampered by injuries, which resulted in his not being selected for the 800 m at the World Championships in Helsinki. He was selected for the 1500 m, but ran a poor tactical race in the final and finished 4th, behind winner Steve Cram. He was yet to reach his peak for 1983, which followed with a 1500 m world record of 3:30.77 in Rieti. A few days later, he finished a close 2nd to Steve Cram in an epic mile race in Crystal Palace.
