Grand National-winning jockey Ryan Mania has announced his shock retirement from the saddle.

The Scot rocketed to prominence when he won the Aintree showpiece in 2013 on the Sue Smith-trained Auroras Encore.

Just 24 hours later Mania came down to earth with a bump when he suffered a neck injury in a fall at Hexham.

His biggest win since Auroras Encore came on the Sandy Thomson-trained Seeyouatmidnight back at Aintree this April.

The 25-year-old told the Yorkshire Post said an ongoing battle with his weight was the main reason for his decision.

"Of course I am sad that I am stopping, but it has been at the back of my mind for some time," Mania said.

"People don't always see the sacrifices that jockeys have to make if they're to make the weight, and also the travelling and the time away from your family.

"I'm not being fair to myself if I carry on being miserable.

"I rode four winners the other week and I just didn't get that kick out of winning."
