Since 2013 the Calgary Marathon Race Weekend has been the platform for a number of GUINNESS WORLD RECORDS™ title-attempts, including 12 that have been successful.

GUINNESS WORLD RECORDS™ is partnering for the first time with the 2020 Calgary Marathon to provide free on-site verification to pre-registered record-breaking hopefuls like you.

An official Guinness World Records adjudicator will be at the finish line to confirm if your feat was Officially Amazing™!

A Guinness World Records title attempt will make your run in Calgary even more special, whether you’re trying to make a personal record or benefit a charity close to your heart. An official attempt can bring additional awareness to your efforts, so be sure to include details about your charity run within your application.

Planning to run with friends and family?  Make history together and apply for a team-based record title, including Fastest marathon by a linked team, Fastest marathon in a three-person costume, or Fastest marathon in a ten-person costume.

Learn more about the current record titles and their minimums to see which category is right for you or your team.
