TREADMILL
WORLD RECORD

In January 2025, I ran for 48 hours on a treadmill at the National Running Show in Birmingham to try and get a second Guinness World Record (after my Ireland World Record in 2024). 

In 48 hours, I ran 370.90 km (230.46 miles), which officially broke the record for the greatest distance run on a treadmill in 48 hours (female).​

About the Challenge

I'd only ran on a treadmill for 4 hours before coming into this challenge. So I knew 48 hours would be tough. My plan was to run a 'standard' 24-hour run, but a bit more relaxed. 8x 3-hour blocks starting at 11kph getting slightly slower each time. I had my chief crew member Kate Strong (also an endurance Guinness World Records title holder for the greatest virtual distance on a static cycle in one hour (female)) on hand to keep me on track. 

​

I started running on the Friday before the show at 2:30pm while everyone was setting up stands around me. It was crazy, but I had a good team on hand I broke the record at 6am on the Sunday, then decided to hike it out to the finish time. By 2:30pm, with 48 hours under my belt, I had added 30km to the existing record, with minimal sleep. The best thing about the experience was being in a static location, so people could come by for a chat or to run next to me on the support treadmill.  

​

I was also being monitored and analysed by a team from Liverpool John Moores University led by Dr Jamie Pugh every hour – only 6% of Sports Science is exclusively conducted on women and we need to see this increase. ​

There is an article that goes into the challenge and motivations in more detail on the Guinness World Record website if you'd like to learn more. I also have a breakdown of each day of the challenge on my Instagram channel.
