50,000 join Cambridge Festival for ideas, debate and discovery

Cambridge turned curious, noisy and gloriously hands on this spring as the Cambridge Festival wrapped its 2026 edition with a surge of public energy, big ideas and record numbers.

Across 18 days from 16 March to 2 April, more than 50,000 interactions were logged across a programme of more than 360 events, as laboratories, lecture halls and public spaces opened their doors to anyone with a question to ask or something to discover. The result was less a traditional festival than a city-wide conversation between researchers and the people their work hopes to reach.

Families helped set the tone. Thousands poured into the Big Biomedical Campus Day and the Cambridge West Open Day, while the Family Weekend drew more than 8,000 visitors in a lively mix of experiments, performances and practical learning. At the University Centre alone, 3,000 people took part, with 1,000 stopping to learn CPR through a partnership with East Anglian Air Ambulance, turning curiosity into lifesaving knowledge.

School pupils arrived in force. More than 1,200 students from key stages 2 and 3 took over Cambridge West across dedicated school days, swapping classrooms for hands on encounters with science, technology and research in action.

The appetite for big ideas was just as strong. Every keynote event at the Cambridge Union sold out, pulling in more than 2,000 attendees across four evenings. Giles Yeo unpacked the science of obesity, and Carol Vorderman tackled questions of truth in a crowded and animated chamber. A patient-led discussion on the future of breast cancer care brought a more personal, urgent note, connecting cutting-edge research with people’s own experiences.

A strong note of civic engagement ran through the programme. Sharing the Mic, a school student led debate at the Cambridge Union, brought together young people and politicians for a lively exchange on the issues shaping their futures. Representatives from 12 schools took part alongside Cllr Heather Williams for the Conservatives, Cllr Peter Rees for the Greens, Pippa Heylings MP for the Liberal Democrats and Daniel Zeichner MP for Labour, in a discussion that placed student voices firmly at the centre of the conversation.

The festival’s wider civic dimension was equally visible through its partnerships. Community organisations including Abbey People, Cambridge United Foundation and Clarissa’s Campaign brought local knowledge and people’s own experiences into the programme, while collaborations with Anglia Ruskin University, Cambridge School of Visual and Performing Arts, museums and schools helped embed the festival across the region.

Large-scale public events added to the sense of momentum. More than 6,000 people attended the Big Biomedical Campus Day and Cambridge West Open Day alone, with queues, conversations and demonstrations running from morning into late afternoon.

Behind the scenes, the festival doubled as a training ground for researchers learning to take their work beyond academia. More than 1,200 researchers and academics contributed, delivering over 1,500 hours of engagement. Many events were collaborative, with multiple contributors shaping each session and widening the reach of their work.

That sense of real-world impact extended beyond discussion. At an event in the Grand Arcade, led by the University of Cambridge Repair Cafe team, 37 items were fixed, preventing 35kg of waste and saving an estimated 711kg of CO2 emissions, roughly equivalent to growing 12 tree seedlings for a decade.

Backed by partners including AstraZeneca, the Cambridge Festival continues to expand its reach and ambition, positioning itself as a major moment in the UK’s public engagement calendar.

If this year proved anything, it is that when Cambridge throws open its doors, people are ready to walk in, roll up their sleeves and join the conversation.
