Olympic sprint champion Allyson Felix continued her comeback at the Oslo Diamond League meeting on Wednesday night, cruising to an easy 200m victory after a hamstring injury sidelined the American for most of the past year.

Felix was fast out of the blocks and never looked back, keeping a big lead over the pack as she eased to cross the line.

Her time of 22.73, however, was more than a second off her personal best, highlighting her struggles.

Djibouti’s Ayanleh Souleiman, the world indoor 1,500 metre champion, had no problems with his form as he convincingly won a star-studded mile with a time of 3:49.49.

Middle distance great Hicham El Guerrouj, of Morocco, holds the 1,500m world record with 3:26.00.

Souleiman pulled away on the final lap and was never threatened as several runners in the chase pack mounted a late charge.

American Tianna Bartoletta needed just two jumps and a big personal best to win the long jump.

After a poor first attempt she leapt 7.02, the world’s best jump this year, and passed the rest of her attempts as her nearest rival was more than 20cm behind.

French pole vault world record holder Renaud Lavillenie failed to impress, however. He came into the competition when most of his competitors were already out, and secured an easy victory.

But his winning vault of 5.77 was far from his best and his three attempts at 5.83m were unimpressive.
