A man who battled back after having a stroke six years ago has now set a new world record for travelling almost ten miles - on a space hopper!
Dr Martin Mienczakowski, a research associate from Bristol University, doubled the previous record for the furthest distance travelled on the giant bouncy ball in 24 hours.

One of my ambitions has always been to set a world record.
Martin suffered a stroke on Christmas Day in 2009 aged just 25. He completed the space hoppper challenge to raise money and awareness for the Stroke Association.
Only 5% of people who suffer a stroke will make a full recovery, 6 years later, Martin is now fighting - and 'bouncing' - fit.
Just 6 months after his stroke, Martin took on a 100 mile trek through the Scottish Highlands despite the impact of his illness.
Martin says throughout his recovery he's concentrated on how he can do things and not why he can't do them.
The Guinness World Records will need to verify the achievement, but the previous record was 5 miles.
