Salary benchmarks
Our take
As a way to keep fit, running has shot up in popularity in recent years, partially due to accessibility, especially during the pandemic. But for those who want to take running to the next level – whether that be a 5K or a marathon – it can be difficult to know where to start in terms of a training plan. Runna supplies an app with personalised training plans for all types of runs, to help people achieve their running and fitness goals.
Runna was founded in 2020 by running enthusiasts for running enthusiasts, in response to the lack of tools – save paying a professional trainer – available to help runners train. Although there is a wealth of day-to-day running apps available, where Runna stands out is in providing training plans for specific races, which can be distinguished by distance and goal time. In addition, it does this whilst maintaining a sense of community, which has proven to be a popular feature amongst other running apps, and still caters to a range of experience levels.
Runna has since consistent subscriber growth since its launch, serving thousands of users globally. The company plans to build and scale into the future, reach more customers, and expand its team.
