Guinness World Records has teamed up with the Virgin Money London Marathon for the ninth consecutive year to offer record verification on the day of the iconic race. 
A huge 58 world records are being attempted this year, featuring a total of 68 runners, and a team of Guinness World Records adjudicators will be on hand to check costumes, verify times and confirm successful runners as official GWR title holders, earning them a place in the 2017 book.
Ahead of this year’s event, here below we detail six record attempts set to take place on the day.

Ian Bates (45), a bus fleet engineer from Crawley, West Sussex, has sculpted arguably the finest costume ever to grace the circuit.

Phillip Box (30) has already run over 70 marathons and ultra-marathons, and having completed a personal goal of running 100 miles in under 24 hours last year, he decided strapping a tumble dryer to his back was the only way to keep pushing himself! Once the Virgin Money London Marathon is behind him, Phillip plans to conquer Snowdon with his affectionately named ‘Tumble’, who weighs in at 24kg. Phillip is raising money for Polycystic Kidney Disease research, an incurable condition from which his four-year-old nephew suffers.
