Aussie cycling star Caroline Buchanan seriously injured in road accident

Australian cycling star Caroline Buchanan has revealed she has spent the beginning of 2018 in intensive care, after she was involved in a one-car road accident in New South Wales prior to the new year.

Buchanan, 27, is a two-time Olympian and eight-time world title winner in both BMX and mountain bike disciplines, and posted to Instagram the extent of her injuries, which include a broken sternum and collapsed lung.

Included in the post was a scan of her chest which showed the broken sternum.

"I wouldn't say 2017 ended quite as planned," Buchanan said.

"Its been a rough couple of days in ICU after a vehicle roll. I just moved to a private room and everything is moving in a positive recovery direction. Injuries are a broken sternum, broken nose and collapsed lungs.

"I'll keep you guys up to date as we go. Happy New Year! Off season just got a little more tough."

Buchanan is coming off a successful 2017 season, in which she finished an overall second at the BMX Championships held in South Carolina in July.

She also won the world title in the mountain bike four-cross in Italy in August, while she was named Canberra's 2017 female athlete of the year at the ACT sport awards in December.
