Running for a Cause

Would you like to run a 10K, a half-marathon, or a marathon in 2027?

Join the Gustave Roussy team and turn your athletic challenge into a commitment to cancer research.

With a “Solidarity” or “Commitment” race bib, you’ll run in Gustave Roussy’s colors and rally your friends and family to support your fundraising efforts.

Every kilometer you run is a challenge for you. Every donation you raise supports cancer research.

Your race bib for 2027

There are several races where you can take on the challenge while representing Gustave Roussy.

Our Upcoming Community Service Challenges

Charity Race Bibs: How Do They Work?

The concept is simple: you pay half the price for your race bib (the registration fee) and raise donations for Gustave Roussy.

Fundraising is not a second payment.
These are donations from your friends and family, paid directly to Gustave Roussy.

Each donation entitles the donor to a tax deduction of 66% of the donation amount for individual contributors, or 60% of the donation amount for corporate donors. 

With a race bib that shows solidarity and commitment

Choose Gustave Roussy as the beneficiary organization, buy your race bib at half price, and set up your fundraiser.

Then, it’s up to you to rally your friends and family to reach the minimum fundraising goal for your race.

Steps: 

  1. Choose your race
  2. Reserve your race bib by paying the registration fee
  3. Set up your Gustave Roussy fundraising campaign 
  4. Rally your friends and family
  5. Reach your goal
  6. Lace up your sneakers and run!

With a “commitment” race bib, you don’t have to rely on a random drawing like you would with a standard race bib: you’re directly supporting Gustave Roussy, and you’re guaranteed a spot at the starting line of the race of your choice!

They run to advance research

Today, thanks to research, I was able to run a marathon!

Olivier, who was diagnosed with Hodgkin’s lymphoma and is being treated at Gustave Roussy

Diagnosed with Hodgkin's lymphoma at age 23, Olivier received treatment at Gustave Roussy. Today, he runs to raise awareness about the importance of research and to support those who are still undergoing treatment.
