International 400m gold medallist Iwan Thomas will officially launch the Gatorade 10K run at Bluewater tomorrow with a challenge for other runners.

Iwan has run 400 metres on a treadmill in a time of 48 seconds and tomorrow (Tuesday) he'll be asking people to try and beat that time.

It is one of a number of interactive events he'll be hosting. He will also offer advice and answer any training questions ahead of the race on Sunday June 5.
