Important update 2020:
Unfortunately, due to the restrictions in place globally, Guinness World Records has made the difficult decision not to attend Blackmores Sydney Marathon in 2020. We have been unable to conduct face to face Adjudications during the pandemic and with no end date confirmed we are unable to commit our full attendance at this year’s event. Applicants that run the event in 2020 are welcome to submit their evidence as per a standard application for us to process. We hope to return in 2021 offering on the day Adjudications for those runners who wish attempt to break a Guinness World Records title.
