What is the 5K to Fight Histio?

The 5K to Fight Histio takes place each year at Hudson River Park in New York City. It started with under 200 registrants in 2013 after Liam's Lighthouse Foundation and its supporters wanted to expand their outreach and awareness during the time they spent together in New York City. In previous years we reached almost 500 registrants prior to race day! This 5K helps families from around the world gather together for a cause they hold close to their hearts and raise much needed funds for Histiocytosis at leading researching hospitals in the US. Join us and REGISTER today!

What Histio Families Are Saying...

All I can say was that this weekend was absolutely incredible. I'll never forget the stories that were shared and the people that I met...thank you Liam's Lighthouse!!!!" - M.Rivera (NY)

"I can't wait to be submerged in the heart of NYC for 4 days with my camera in tow to catch the excitement of this event and NYC itself (except for while I'm running haha)... I have a feeling this is going to be yet another life altering experience for me, one I'm truly looking forward to!!!" -J.Marie (NH)
