RunThrough, the UK-based mass participation event organiser, has announced it is seeking its first ever title sponsor, marking a new step as it expands its growth across the UK and internationally.
Since launching in 2013, RunThrough has built a year-round calendar of events, including events such as Run Alton Towers, Hampton Court Palace Half Marathon, and the Surrey Half Marathon.
The organiser, which describes itself as the world’s fastest-growing running event company, expects to host more than 350 events with over 400,000 participants in 2025.
RunThrough’s participant numbers have reportedly increased by over 50% year-on-year, rising from 211,000 in 2023 to over 320,000 in 2024.
The company projects further growth in 2026, with plans to accelerate its international expansion by hosting events in France, the USA, Spain, Switzerland, and Qatar.
Jack Williams, Chief Executive Officer of RunThrough, said “We are proud to be recognised as the world’s fastest growing running events company, and this is the perfect moment to invite a partner to share in our journey.
“RunThrough offers more than exposure, it’s a chance to align with an audience that is highly engaged, loyal, and passionate about the active lifestyle.
“A title sponsor will have the opportunity to become truly embedded in the heart of the running community, with visibility and engagement across the UK and internationally, all year round.”
Russ Jefferys, former parkrun Chief Executive Officer and Founder of MOVE Sports Marketing, added “I have worked across the endurance and mass participation space for many years, and I can say with confidence there is no brand platform more exciting right now than RunThrough. The variety of events and races is unmatched, and the company’s trajectory is extraordinary.
“RunThrough has become a movement, inspiring participation week in, week out. For brands, this represents a unique opportunity to engage consistently and meaningfully with a vast, growing audience.”
