In the vibrant tapestry of Kenya’s philanthropic landscape, the Mater Heart Run stands out as a powerful testament to the impact and importance of local giving.
What began as a vital initiative to mend ailing hearts has blossomed into a nationwide movement, embodying the spirit of community solidarity and demonstrating how homegrown efforts can transform lives.
The Mater Cardiac Program, an ambitious undertaking by Mater Hospital, was established in 1995.
Its genesis stemmed from a stark reality: many Kenyan children from economically disadvantaged backgrounds suffered from severe heart conditions with no access to quality treatment.
These young lives were often destined for premature death, a tragic outcome the Sisters of Mercy, founders of Mater Hospital, sought to avert.
Their core values of compassion and uplifting the underprivileged drove the program’s inception.
The first open-heart surgery under this program was successfully performed in 1996, marking a pivotal moment in Kenya’s healthcare history.
To sustain this life-saving work, the Mater Heart Run was inaugurated in 2002.
Initially confined to Nairobi, the run quickly resonated with the public, growing exponentially to encompass ten towns across Kenya.
These include Nairobi, Mombasa, Machakos, Kakamega, Kisumu, Nakuru, Eldoret, Nyeri, Kericho, and Bomet, symbolizing a truly national effort in fundraising.
The event has transcended its origins as a mere run, evolving into a unifying force where individuals, families, schools, corporate entities, and well-wishers converge to contribute to a shared humanitarian cause.
The Mater Heart Run 2025 took place on Saturday, May 31st, 2025, starting at 7:00 AM at the Kenyatta International Convention Centre (KICC).

Tangible Impact: Mending Hearts, Transforming Futures
The impact of the Mater Heart Run is not just anecdotal; it is quantified in thousands of saved lives. By 2023, the program had facilitated over 3,000 heart procedures.
This figure continued to climb, reaching 5,448 beneficiaries by March 2024 and an impressive 5,684 children by April 2025.
These procedures encompass critical interventions, including complex open-heart surgeries and less invasive cardiac catheterizations, offering a new lease of life to children who would otherwise have no hope.
Beyond the surgeries, the Mater Cardiac Program actively engages in preventive healthcare.
Since 2008, the hospital has conducted free cardiac outreach screening camps nationwide, screening over 157,596 children for rheumatic and congenital heart conditions by April 2025.
These camps are crucial for early detection, community education on preventable heart diseases, and identifying new candidates for the cardiac program.
The stories of beneficiaries underscore the profound difference made.
Rachel Mungare, a recipient of the Mater Heart Run’s support, shared her transformative journey: “Mater offered me an opportunity to go for surgery in London for treatment, took care of everything, and when I came back, they gave me post-operative care.” Her experience highlights the comprehensive support provided, extending beyond the surgical procedure to crucial aftercare.
Dr. Gladys Njihia, a paediatric cardiologist at Mater, vividly describes the transformation in these young patients. “When these babies and children come to us, they’re often in and out of the hospital, not able to feed, go to school, or even play. Their quality of life is inferior,” she noted.
“Once we’ve done the surgery or interventions, they undergo a huge transformation – they thrive.” This professional perspective emphasizes the tangible improvement in the children’s well-being and life prospects.
The Power of Local Giving in Action
The Mater Heart Run is a shining example of the potent force of local philanthropy.
The cost of an open-heart surgery can range from Kshs. 1.5 million to Kshs. 2.5 million, a sum largely unaffordable for the impoverished families the program serves.
The funds raised through the Heart Run bridge this critical financial gap, making life-saving procedures accessible.
For the 2025 edition, the Mater Heart Run aims to raise Kshs 120 million, a testament to the ambitious scale of local fundraising efforts.
The success of the Mater Heart Run mirrors a broader trend of escalating local philanthropy in Kenya.
The nation was recently ranked as the second most generous country globally in the World Giving Index 2024, published by the Charities Aid Foundation (CAF).
This remarkable achievement signifies a deep-rooted culture of giving, volunteering, and mutual support within Kenyan communities.
The report noted that 82% of Kenyans reported helping a stranger in the previous month, 56% donated money to charity, and 52% volunteered their time, highlighting a robust tradition of informal giving and community support.
Local philanthropy, as exemplified by the Mater Heart Run, is fundamentally different from international aid.
It is rooted in the communities it serves, drawing on the resources, knowledge, and commitment of local individuals and organizations.
This localized approach fosters a crucial sense of ownership among community members, encouraging them to actively participate in development processes.
It allows for more responsive interventions tailored to specific local needs, a stark contrast to the often top-down approach of external aid, which can sometimes create dependency rather than self-sufficiency.
Sister Dr. Mary Ngui, CEO of Mater Misericordiae Hospital, eloquently captured the essence of this local collective impact. “At this, just pause and ponder on the lives – not numbers – saved because of your support,” she urged.
“These are the precious lives of our children, touched and given a new lease of life. They’ve been given the chance to be like any other child, thanks to your generosity.”
Her words underscore the profound human element at the heart of this philanthropic endeavor.
A Model for Sustainable Development
The Mater Heart Run’s sustained success over two decades underscores its effectiveness as a model for local philanthropy.
It has not only provided direct medical intervention but also built local capacity by training medical staff in cardiac care, contributing to the long-term strengthening of Kenya’s healthcare system.
Corporate partners like Isuzu EA, Safaricom, Naivas, Fidelity Insurance, and Kenya Airports Authority (KAA) have consistently supported the Mater Heart Run, injecting significant funds and mobilizing their employees.
For instance, KAA pledged KES 500,000 for the 2024 run, while Isuzu EA sponsored KES 250,000 and had 150 employees participate.
This corporate social responsibility (CSR) is a growing facet of local giving in Kenya, with companies increasingly investing in community initiatives.
The Mater Heart Run is more than a fundraising event; it is a movement that cultivates a culture of empathy and collective action.
By bringing together diverse segments of society for a common cause, it reinforces social cohesion and inspires further acts of giving.
It highlights that profound change can be driven from within, with ordinary people, local businesses, and community leaders rallying to address critical needs.
The run’s continuous growth and its ever-expanding network of participants and beneficiaries serve as a powerful testament to the immense potential of local philanthropy in fostering sustainable development and building a healthier, more compassionate society in Kenya.
