A TEENAGER will do a half marathon along the A19 on a unicycle to raise funds for the NHS later this week.

Rory Vince is hoping to complete the entire route from York's Theatre Royal to Easingwold on one wheel.

The York College backstage arts student wanted to do something different.

"I've seen lots of ways of fund raising for the NHS, but none of them really grabbed me," he said.

"I will do one that is very different and not something you do every day."

Rory, now 17, has been riding a unicycle since he was given it as a Christmas present when he was 13.

He even went to his school prom on it.

"It took a few days to learn but after a week I was riding it around Easingwold," he said.

He lives in the town and when he was looking for the best way for a unicycle to travel between York and Easingwold, the A19 came up top.

"It's safer than country roads because on country roads you cannot see what's coming round the corner, he said

"On the A19, you can see people more."

The A19 is also generally flat and it is difficult to ride a unicycle up a hill. They have no gears and a small BMX size wheel.

His mother Debra will drive her car behind him with warnings to other motorists there is a unicycle ahead.

He hopes to complete the distance in three hours, at about 6mph, including pauses for drinks on Friday, provided the weather allows.

He originally planned to raise £250 but has now raised that to £1,000. So far he has raised more than £760. Donations can be made via https://www.justgiving.com/fundraising/rory-unicycle.
