Ever been jogging or just out in public and suddenly struck by the sight of a cis man confidently running towards you shirtless, nipples showing, uncensored, uncovered while you are sweating like a pig, your nipples deemed too sexual to be out in public? If yes, and if it annoys the shit out of you: join the TITTYTHON! In this participatory performance/marathon we will run however we like, tits and chest out if you like or with the support of a sports bra if needed, as a sign against the sexualisation of breasts. During our route through Amsterdam there will be performative interventions by us, it will be sweaty, defiant and feminist! See you there!
