The British school teacher is doing it to raise money for cancer research.
Thirty-year-old Neil O’Maonaigh-Lennon, a teacher from North London, has been on a incredible journey for the past three months. Since September, he’s been running counter-clockwise around the coast of Britain. His goal is to run 105 marathons in 105 days. Were he to complete this feat, he will smash the current Guinness world record, which stands at 52.
Though he isn’t being monitored by the Guinness Book Of World Records, O’Maonaigh-Lennon is using a satellite tracking device to record his mileage.
“My aim from day one was to run every step of the way,” he said. “There’s no walking. It’s definitely a question of mind over body.”
The English marathoner has been completing this feat to raise approximately $15,000 for cancer research. Both of his grandfathers died from the disease.
O’Maonaigh-Lennon completes each marathon in approximately seven hours. When he finishes his daily marathon, he marks the road and uses that mark as his starting point the next day.
His last marathon will take place on Thursday in West Sussex, England.
