GB Ultras 2023: Ultramarathon runner stripped of victory after Strava app shows she used car for 2.5 miles

A Scottish ultrarunner was caught off guard by tracking data from a running app, which indicated a 2.5 mile abnormality during a high-profile race. Dr Joasia Zakrzewski, finished third in the 2023 GB Ultras Manchester to Liverpool 50-mile race earlier this month, just weeks after winning a 48-hour race across 255 miles in Taipei.

The record-breaking 47-year-old athlete, who often runs hundreds of kilometres events, has been disqualified from the race after data uploaded to Strava - a running and cycling app - revealed she had used a car for a 2.5-mile stretch of the race.
