100K in 30 Days was founded by Louth couple Niall Carroll and Cara McAdam and launched in 2020 after Cara was diagnosed with breast cancer.
Cara is an avid runner and ran all during her treatment which inspired her husband Niall to setup the 100k in 30 days fundraiser.
Between the 2020 and 2021 events, €3m was raised, going directly into funding breast cancer research and clinical trials.
This independently-run event, sponsored by Sherry FitzGerald, has become Ireland’s largest virtual challenge in just two years and has had 38,000 people take part from 36 countries worldwide.
Breast Cancer Ireland and the organisers are calling on everyone, runners, walkers, those in wheelchairs, families, colleagues, schools, community groups, and sports teams based in Ireland or abroad, to join the #pinkarmy and take part in the June event.
