Guinness World Records is partnering with the Virgin Money London Marathon for the 13th successive year, giving participants in the world’s greatest marathon the chance to become official record title holders.

An adjudicator will be at the finish line to tell you whether you have successfully achieved the record you are attempting - something which is usually a paid-for service but, for this day only, the verification is done for free.

At the 2019 event there were 40 new Guinness World Records titles achieved from 79 attempts, ranging from the fastest marathon dressed in a tent to the fastest marathon with two runners handcuffed together!

You can help make the 2020 Virgin Money London Marathon the best yet by attempting to break a world record on the day.

Please note that in order to apply for a record, you must have secured a place in the 2020 Virgin Money London Marathon on Sunday 26 April. Places are not available via Guinness World Records.

To make sure our records are fair and up to date, some changes have been made to our marathon record categories following a thorough year-long review.

The focus of the review was to ensure we’re not inadvertently discriminating against any groups, perpetuating any stereotypes, or bringing any professions into disrepute. Or put simply, ensuring that our records reflect the world we live in today. We’ve also streamlined our record categories, which has included merging similar record categories and discontinuing some record titles.

However, the review has also resulted in some exciting new categories being created and leaves hundreds of marathon titles to choose from. Attempting a Guinness World Records title will not only enhance your personal London Marathon 2020 experience, but can also help raise awareness and money for your chosen charity. Who knows, you might make history! Read about last year's record breakers to get inspired.
