With marathon participation continuing to rise globally, many runners experience painful skin irritation caused by hours of repetitive movement. It’s a problem widely recognized within the running community, referred to as “runner’s nipple”, yet mostly overlooked in race prep, with conditioning, nutrition or hydration, often taking priority over skin protection. While experienced runners already know Vaseline® Jelly can protect against chaffed and bleeding nipples, countless first-timers remain unaware of this simple preventive hack. As part of the brand’s partnership with the TCS London Marathon, Vaseline gave participants free products, before and at "Nip Stops" along the course — ensuring that participants of all levels, from first-timers to experienced professionals, keep their eyes on the finish line while the friction is handled by Vaseline.
