Boost has kicked off a 5k challenge on fitness platform Strava, marking the beginning of a new commercial partnership aimed at driving a broad campaign.

Created in collaboration with independent media agency The7stars, the partnership gives the AG Barr-owned brand access to Strava’s global community of over 150 million users.

The in-app ‘Boost Sport 5k’ invites Strava participants to take on a manageable fitness goal. Those who complete the challenge between 31 May and 8 June will receive a custom Boost badge and be entered into a prize draw to win a year’s supply of Boost Sport and branded gear.

Abbi Johnstone, BOOST Senior Brand Manager, said: “There’s a BOOST for That is all about supporting people in the everyday moments that matter. This campaign brings that spirit to life in a big way — putting BOOST right where our audience is grafting, whether they’re smashing a 5K or just out for a run to clear their head.”

Maddie Northwood, Account Manager at the7stars, added: “We set out to deliver a media strategy that reflects the real energy of BOOST’s audience. This campaign is about everyday graft, not glossy perfection — and the Strava partnership captures that brilliantly by championing effort, not aspiration.”
