Sheena Stewart, 32, from Mount Vernon, took on the challenge to raise money for the Thistle Foundation, which helps her brother Alistair to live independently in Renfrew.
The charity has supported people with disabilities and long term health conditions for more than 70 years.
In 2013 Sheena ran 14 events, including the Great Scottish Run Half Marathon, Highland Perthshire Half Marathon and the Zombie Night Run in Helensburgh. She has raised £950 of her £1000 target. To donate go to www.justgiving.com/Sheenashundredmiles.
