WORLD Championship ace Chris Harris has been added to the star-studded line-up for Peterborough captain Ulrich Ostergaard's testimonial.

The former British champion and British SGP winner will compete in some exhibition races during the '10 Year Spectacular' at the East of England Showground on Sunday (March 13).

A delighted Ostergaard said: "It is brilliant to have 'Bomber' involved in my testimonial.

"We spoke to him several weeks ago about riding, but he had Polish commitments at the time so couldn't commit.

"They've now fallen through so he can be part of my day."

Harris, who has his own testimonial at Coventry the following weekend, becomes the second current GP racer to grace Ostergaard's big day along with Niels Kristian Iversen.

Ostergaard has also confirmed that two well-known speedway figures will complete some demonstration laps during a packed schedule.

Sky Sports expert Chris Louis and former Peterborough star Olly Allen, who retired from racing after a crash in Panthers' colours last season, will both take to the Alwalton track during an event which begins at 2pm.
