This April, Demi Longman, Director of British social media agency Social Advantage, will take on the challenge of the iconic TCS London Marathon. While the 26.2-mile course is a physical and mental test, Demi is running with a purpose that extends far beyond the finish line. She is raising funds and awareness for CALM (Campaign Against Living Miserably), a leading mental health charity dedicated to preventing suicide and supporting those in crisis.
For Demi, this cause is deeply personal. Reflecting on her motivation, she shared, “Having a ballot place gives me the privilege of choosing a cause close to my heart to support—and I’ve chosen CALM. Mental health struggles have touched the lives of many people I love—friends, family, and even myself. In 2024, I hit rock bottom, but thanks to the right support, I’m here today, stronger and more determined than ever. This makes my fundraiser deeply personal.”
CALM’s mission is to save lives by creating a culture where people feel empowered to speak openly about their mental health and seek help without stigma. The charity provides vital resources, including a free and confidential helpline and web chat service available seven days a week. With suicide being the leading cause of death for men under 50 in the UK, CALM’s work is critical, and Demi’s support will contribute to their life-saving efforts.
“Mental health issues are often invisible and unspoken, yet they impact so many,” Demi explained. “By running the TCS London Marathon, I hope to raise awareness and funds to ensure no one has to face their darkest moments alone. Every donation—no matter the size—helps CALM continue their vital work.”
Training for the marathon has been no small feat for Demi, who balances her demanding role at Social Advantage with rigorous running sessions. She credits her determination to the support of her family, friends, and colleagues, as well as the resilience she’s built through her own mental health journey. The team at Social Advantage is rallying behind her, offering encouragement and sharing her fundraising efforts across the agency’s platforms.
Social Advantage has always championed meaningful causes, and Demi’s participation in the TCS London Marathon exemplifies the company’s values. Her decision to support CALM aligns with the agency’s commitment to fostering open conversations about mental health, both within the workplace and in the broader community.
The TCS London Marathon is a spectacle of human endurance and solidarity, drawing thousands of runners and spectators from around the world each year. Demi is eager to contribute to this incredible event while championing a cause that resonates so profoundly.
