How's this for pedal power? A Scottish student has become the fastest person to cycle around the world.
Mark Beaumont finished his journey at famous monument the Arc de Triomphe in Paris, France, at 2.30pm on Friday. The feat took him 195 days.
The previous record was 276 days - so he smashed that by loads.
Mark cycled through 20 countries on his 18,000-mile, seven-month journey. He hopes to raise lots of charity cash by completing his challenge.
Mark, who lives in Fife, started his trip in Paris on 5 August.
His route included Pakistan, Malaysia, Australia and New Zealand.
He's had a few dramas - like the time an elderly driver knocked him over in America.
Mark also had his wallet and camera stolen.
Officials are getting ready to confirm the record.
"It has been logged as an official attempt and it seems everything is in order," said a spokesman for Guinness World Records.
The organisation Mark is cycling for supports several charities - including ones which protect wildlife, help disadvantaged children and support homeless people.
