Threshold Sports, one of the UK’s fastest growing sports events agencies, has recently announced it has bought the Endure24 event series from Race Solutions Ltd.

Endure24 - a 24-hour trail running relay race - has developed a cult following since its launch in 2012. Led by founder and experienced race director Chris Sumner, the original event in Wasing Park near Reading was joined by a sister event in Bramham Park near Leeds. In 2019 over 10,000 people attended the weekend events to race as solo runners, compete in super sociable teams of up to 12 or just to provide support through the dark hours.

These events are seen as an ideal addition to Threshold Sports’ existing events portfolio, as they continue their journey of making make world class endurance challenges accessible, achievable and enjoyable for more people.  

Founded in 2008, Threshold Sports’ innovative attitude towards creating extraordinary outdoor challenges has enabled the business to continually deliver cutting edge mass participation events for people of all abilities.

CEO of Threshold Sports, Nick Tuppen, said: “We are enormously excited to announce that from today we welcome the Endure24 event series into the Threshold Sports portfolio. We have been admiring the incredible work that Chris and his team have put into making Endure24 one of the best loved events on the UK running calendar. He shares the same passion we do for opening the world of endurance challenges to a wider audience and has led the way in creating a truly unique set of events.”

Tuppen continued: “We will be working closely with Chris in the coming year to ensure we don’t lose any of the magic that thousands of runners and walkers have come to love. At the same time, we will be looking to bring Threshold’s wider team and experience to the party to secure Endure24’s place in the calendar long into the future.”

Founder of Endure24, Chris Sumner, commented: “This feels like the perfect next step for Endure24 and I am looking forward enormously to working with the Threshold team over the coming year. They are a company that share our values and commitment to organising world class events and I’m sure that bringing their expertise in marketing, sponsorship and charity engagement to the events will move Endure24 onto an even brighter future.”
