Piotr Lobodzinski of Poland and Suzy Walsham from Australia won the men's and women's races at the annual Vertical World Circuit climb in Hong Kong on Sunday.

All in the name of a good cause - and definitely not for those that like to take the elevator!

Klaxons marked the start of the Race to Hong Kong finale - the steps give you a big clue - competitors run up several flights of stairs in a race to the top

The finale was held at the International Commerce Centre in Hong Kong - 1600 competitors in total and 2,120 stairs to ascend.

Men, women and children compete.. and there's even a section for the seniors - just don't ask how their knees held up after crossing the finish line!

There was an elite aspect too - 22 world-class athletes from 12 countries have battled each other in the Vertical World Circuit.

Darren Wilson finished first in Hong Kong in 11 minutes and 52 seconds.

Suzy Walsham won the women's category in 14 minutes and 14 seconds. Walsham was also crowned women's series champion with Piotr Lobodzinski coming first for the men.
