Gemma, 33, of Thurlby Way, Maidenhead, suffered the condition for months.
Sunday's 'Pramathon' was her way of thanking everyone who helped her get better as her husband Ben, two-year-old daughter Molly and supportive friends joined her on the route along Windsor's Long Walk to the Copper Horse.
Gemma and her 'team' were walking with their prams and pushchairs to raise money for PANDAS, the charity that helps mums suffering from post-natal depression.
Waitrose had donated vouchers to buy water, breakfast and snacks.
The event is well on the way to raising £1,000.
Gemma said: "Mental illness is so isolating, dark and horrendous.
"By supporting PANDAS, sponsors are making sure help is out there and is accessible and relevant."
