Members of British Military Fitness Glasgow, based out of Rouken Glen Park, will take part in a charity challenge raising money for military mental health charity, Combat Stress.
Members will start with an outdoor fitness session at Rouken Glen before running to Bellahouston Park where they will complete a second session before running to Kelvingrove Park for a third session.
Members based around the parks have so far raised over £1,000 for the charity.
The event begins on Sunday at 8:30am from Rouken Glen Park.
