Run, walk or climb to the top and help raise monies for the charity Giant Steps. Registration is already open, so come on Sydney let’s get fit and raise some cash for a great cause.

There are various categories open for runners, walkers, climbers, fancy dress and more, so get your friends together and go crazy. Just for a moment think about how you’ll feel once you’ve made it to the top of the Sydney Tower.

The Sydney Tower Stair Challenge will start from the Pitt Street Mall on Sun-day 23 (registration is open today) from 9.00 am to around 14.00 (depending on grouping).
