Digital fitness platform Strava and its personalised training app Runna have partnered to launch a joint challenge targeting a new record for the most 5K activities completed in a single day on Strava.
Taking place on Wednesday June 3, 2026, the Global Running Day 5K with Runna challenge coincides with Global Running Day. The initiative is designed to encourage widespread international participation by focusing on inclusivity rather than competitive racing.
The premise allows participants to either run or walk a 5K distance on the designated day. Any logged activity on Strava, including GPS tracking, virtual logs, and manual entries across all local time zones, will count toward the global total.
According to the companies, the challenge is positioned as an accessible milestone for new runners, with all paces included in the record attempt. The distance is highlighted as an achievable entry point for building consistent training habits or progressing toward longer distances such as 10K events or half marathons. Participants who complete the 5K distance will receive a co-branded Strava x Runna digital badge for their profile trophy collection.
Additionally, finishing the challenge unlocks a promotional offer providing two weeks of free access to Runna Premium. This incentive is restricted to new customers of the platform. Runna specialises in generating coach-designed, adaptable running plans tailored to an individual’s current pace, schedule, and specific fitness goals.
Athletes taking part are required to upload their logged activities to Strava within three days of the challenge ending. While private and follower-only activities qualify for the overall record total, only activities marked as visible to the public will be applied toward global leaderboard rankings.
