In just three years, the Nairobi City Marathon has grown from a local initiative to a globally recognized event. This year, it has smashed all previous records with over 15,000 registered runners—marking the highest participation since its launch in 2022.
Runners from all 47 counties in Kenya have signed up, joined by participants from 78 countries across the globe. From elite professionals to everyday enthusiasts, the diversity of the line-up reflects the marathon’s expanding appeal.
Organisers capped entries across four race categories to ensure quality and safety: the full marathon (42km), half marathon (21km), 10km expressway race, and a 4km fun run. With all major events sold out, only limited spaces remain for the fun run.
The race route—set along the iconic Nairobi Expressway and ending at Uhuru Park—offers runners a unique view of the capital’s skyline and modern infrastructure. It also positions Nairobi as a prime destination for urban marathons and sport tourism.

With its highest-ever registration and growing international acclaim, the Nairobi City Marathon isn’t just gaining miles — it’s gaining momentum as a flagship event in Kenya’s sporting calendar.
