	Image For future members of the Institut Pasteur running teams, please note:  This year, the coordinators of the Institut Pasteur teams for these two races are committed to supporting the 20th anniversary of Pasteurdon and showing how sport and research embody the same values of tenacity, excellence and team spirit.   They would like to inform you that registering to take part in the 2026 "La Parisienne" and "20km de Paris" races represents a commitment, not just for race day but also in the lead-up to the event. Like a race, Pasteurdon is an event that requires a great deal of preparation. The team members will be asked to take part in joint training sessions, help create symbolic Pasteurian identities in the streets of Paris via Strava, share testimonials about why they are taking part and what Pasteurdon means to them, and use their social media as a platform to talk about their commitment to Pasteurdon and their support for research.   Taking part in one of these races reflects both a passion for sport and a commitment to Pasteurdon! For its 20th edition, Pasteurdon is counting on your support!
