A FITNESS instructor from Boston will put her own strength and stamina to the test when she takes part in a 248 mile bike ride across the Canadian Rockies in aid of charity.

Liisa Chadburn, who works at Creations Gym at the Boston Borough Council run Geoff Moulder Leisure Centre, is set to ride the Rockies in July to raise money for Marie Curie Cancer Care.

The trek starts from Calgary and will pass through the fantastic scenery of spectacular national parks to Lake Louise.

During the ride 35-year-old Liisa will cycle at heights of up to 2,068 metres - almost twice the height of Mount Snowdon - and will cover as much as 65 miles in a single day.

She hopes to raise £3,000 through sponsorship and will take part in the challenge as a member of a team with a friend she met during her travels in Thailand.

As part of her training Liisa has been taking her mountain bike to the Peak District and the Lincolnshire Wolds.

Customers at Creations held a static cycling and boxercise marathon at the gym on Friday to help raise funds for Liisa's big effort and a sponsored Wear Yellow Day is to be held by staff at the borough council's Municipal Buildings headquarters in West Street at Easter.

Anyone who would like to sponsor Liisa can do so by logging onto www.justgiving.com/liisa-chadburn or contacting her at Creations.
