Runna is one of the most exciting fitness startups in the UK right now, and the Strava acquisition only makes the opportunity bigger. In under four years from launch, Dom and Ben built Runna from a website selling personalised PDF training plans to a globally rated running coaching app, a finalist for Apple's iPhone App of the Year, and ultimately an acquisition by the world's largest fitness community. The team has grown to over 150 people across London and Boston, and Strava has publicly committed to investing further in growing both the team and the product. What stands out on Glassdoor (4.9/5 from 31 reviews, with 100% of employees recommending it) is how consistently people praise the culture, the kindness of their colleagues, and the quality of the leadership. Benefits are genuinely strong for a company this size: private health insurance, enhanced parental leave (up to 20 weeks fully paid), Strava equity, a smartwatch as you pass probation, 25 days holiday plus bank holidays, and a paid hour each week to go for a run during work hours. They operate a flexi-hybrid model, typically three days a week in their Vauxhall office. The team runs bi-weekly together, and Workout Wednesdays include exercise plus a free lunch. The main thing to be aware of is that this is a fast-paced startup environment where priorities can shift quickly, which some reviewers flag as a challenge. There is also a slight bias toward hiring passionate runners, though this has been improving. If you want to work on a product that helped millions of runners train, alongside kind and ambitious people, with the backing and scale of Strava behind you, Runna is a brilliant opportunity.

• Earn a salary of £70,000–£78,000 plus participation in Strava's long-term incentive stock programmes. • Work flexibly with 3 days a week together in the Vauxhall office. • Get 25 days holiday plus bank holidays. • Receive free Runna and Strava subscriptions for you and 3 friends. • Access private health insurance with Bupa and workplace pension scheme. • Get a Headspace membership and Modern Health mental wellness platform. • Access Carrot fertility support. • Receive money every year to spend on gear, events, and the gym.

Runna helps everyday runners become outstanding by building an incredible app providing world-class training, coaching, and community for everyone. In 2024, Runna was selected by Apple as one of three global finalists for the iPhone app of the year. In 2025, Runna was acquired by Strava. The tech stack includes React Native, TypeScript, GraphQL, Serverless AWS with Lambdas, DynamoDB, and Snowflake.
