The 62-year-old, from Lenzie, has run about a dozen 10Ks over the years and last year raised money for the Calman Cancer Support Centre, in the grounds of Gartnavel Hospital.

Unwilling to give in, she said she wanted to maintain the lifestyle she had before being re-diagnosed.

Ally's determination to stay healthy is a perfect example of the thinking behind our Active 2014 campaign.
We want to improve the health of Scots in the year of the Commonwealth Games and build a lasting legacy of physical wellbeing.
Working with partners Glasgow Life and NHS Greater Glasgow and Clyde we will be creating exciting opportunities for individuals, communities and businesses to get active as we bid to improve the health of as many people as possible in the community.
The message of this campaign is that even the smallest of changes in activity and lifestyle can make a huge improvement in health.
On the day of the 10K, Ally will complete the route with friends.

"It's a wonderful place because it focuses so much on one-to-one care.
"I was first involved with them when it was still called Tak Tent.
