Following the success of last year’s 100K in 30 Days event, which raised €1.7 million for Breast Cancer Ireland, organisers are calling on people to join the #pinkarmy and take part in the June event.

The event is open to everyone – runners, walkers, those in wheelchairs, families, colleagues, schools, community groups, and sports teams.

100K in 30 Days was founded by Co. Louth (Blackrock, Dundalk) 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 months which inspired her husband Niall to setup the 100k in 30 days fundraiser. Cara underwent a course of chemotherapy treatment and radiation during the first Covid-19 lockdown.


Between 2020 and 2021’s events, €3m was raised to date going directly into funding breast cancer research and clinical trials. This independently run event has become Ireland’s largest virtual challenge in just two years and has had 38,000 people take part from 36 countries worldwide.

Funds raised have gone towards equipment for a new state-of-the-art Clinical Trial Centre due to open at  the new Breast Centre on the Beaumont Hospital Campus in June.

The Shamrock Trial has also benefitted – a new clinical trial into Her2+ breast cancer that is being created to examine a fourth generation drug and its effectiveness as part of the treatment plan, de-escalating the need for chemotherapy in the process.

Also, monies fundraised is supporting specialist breast research nurses in the eight designated cancer centres; as well as Triple-Negative breast cancer research led by Dr Paul Mullan, from the Patrick G Johnston Centre for Cancer Research at Queens University Belfast.


Niall Carroll, Founder of 100K in 30 Days, said: “The success of the event over last two years, throughout a pandemic, has spurred us on to make 2022 the biggest year yet.

“We all know someone who has or has had breast cancer and the purpose of 100K in 30 Days is for everyone, young and old, grandparents to grandkids, to have fun and get the daily steps in while raising much needed funds for Breast Cancer Ireland.

“Over the last two years, we’ve seen €3 million raised which has gone into various research projects but it doesn’t end there. We want to keep raising money to continue these trials so we’ll continue to fund finding a cure for breast cancer.

“I’m very proud of the success the pink army has achieved to date and we’d be delighted to see new faces this year. I hope communities all across Ireland get behind it. Cancer isn’t defeated alone. It takes a village.

“It’s a challenge that can be done in your own time anywhere in the world and you can even get the dog involved!”
