Walkers who are set to step out under the stars have been given some top tips on how to make the most of their training.

There are now 10 weeks to go until this year's Starlight Walk in aid of Macmillan Cancer Support.

Now in its seventh year, the annual fundraiser will see hundreds of men and women walk 13 miles around Norwich's outer ring road.

And in the run-up to the event, people are being urged to make sure they prepare themselves properly for the challenge.

Top tips given by Sportspark fitness adviser Shani Prime are to alternate between brisk walking and a comfortable walking pace, include leg strengthening exercises such as squats, lunges and calf raises and change walking routes to keep motivated.

Ms Prime said: 'It is important to follow the training programme and gradually increase the amount of exercise you perform, because if you do too much too soon it could have negative consequences. And remember, it is supposed to be a fun challenge, so enjoy yourself.'

This year's Starlight Walk, organised by the Sportspark at the University of East Anglia and sponsored by Chapelfield shopping centre, will be held on Friday, June 22, from midnight.

Registration costs �25, which goes straight to Macmillan Cancer Support in Norfolk.
