The Bloody Long Walk in Sydney is a 35km challenge on 4 August 2024 from Palm Beach to the Manly Promenade; the event is owned and operated by the Mito Foundation.

Walk, jog or run and enjoy spectacular scenery whilst raising vital funds to help find cures for mitochondrial disease (mito).

Mito is a debilitating and potentially fatal genetic disorder that impairs the body's ability to convert food into the energy needed to power muscles and major organs; 1 in 200 people are at risk of developing mito. One Australian child born each week suffers a severe or life-threatening form of mito making it the second most commonly diagnosed serious genetic disease after cystic fibrosis.
