A new £100,000 BMX track will be officially opened this weekend.

The facility, at the Knightwood Leisure Centre, in Valley Park, will open with a day of activities including special BMX races and riding displays and advice on how to look after your bike.

The track, which cost around £100,000 to build, is part of Test Valley Borough Council’s Olympic Legacy initiative.

The project took six weeks to complete and it has been open to the public since the start of the school holidays.

During the free launch event, from 1pm to 3pm on Sunday, there will be demonstrations and races, as well as bike help from bike shop DC Cycles.

PSCOs from the local police station will be on hand to give advice on how to keep bikes secure and do free bike coding.

There will be a chance to find out about the new Knightwood BMX club as well as enjoy refreshments from the Knightwood community café, which will have a barbecue and DJ.

Fiona Hoggarth, assistant manager for Valley Leisure who runs the leisure centre, said: “It’s a free family facility, and it’s giving local people another way to have fun and get active.”

Anyone who wishes to ride at the launch must bring a bike and helmet and wear long sleeves and trousers. Elbow and knee pads are also recommended.
