It is World PI Week where communities around the globe are coming together to raise awareness of Primary Immunodeficiencies and show their support for the foundations that are working tirelessly to improve the quality of life of patients in our communities.

It is not too late to join the Virtual 5K we are hosting this week (details below). However, if you cannot join the run, consider supporting our World PI Week Fundraiser.  

Together with our donors, and our generous sponsors, Horizon Therapeutics and Blue Jay Advisory we have raised over $6,500 so far. Consider joining the campaign by donating or signing up to run your own Fundraiser for World PI Week

You will have a full week to complete your 5K, using any tracker you currently use (Runkeeper, Strava, or any other). In the end, post a photo of your run along with our #HyperIgM #HyperIgM5k #WorldPIWeek hashtags.

All participants that complete their Virtual 5K run/walk/roll will have bragging rights, and will receive a Hyper IgM Foundation Cooling Gaiter with Filter that can be used as a mask or to keep you warm during your runs.



Our 5k will be virtual. You can run (or walk) it from wherever you’d like, be it a park, a trail or even a treadmill! You can complete it at your own pace and time using your favorite running app. Plus, there will be prizes for participants with the most sponsors. Post your results anytime before April 30th and receive a certificate to share on social media!
