65km for Cystic Fibrosis is an endurance walk around a 10.8km track in the beautiful Princes Park and Royal Park in central Melbourne. Either take on the full challenge of walking 65km or just walk as many laps as you feel able. Do it on your own or join with some friends for a great day supporting a great cause. Refreshments and massages will be available to all our walkers. All proceeds will go towards research or clinical improvements for cystic fibrosis.
