MORRISTOWN, N.J. – Xyzal, an Opella brand and leading allergy brand, becomes the first official allergy sponsor of the 2026 Boston Marathon presented by Bank of America to reinforce a simple but powerful idea: "Allergy relief tonight. Rise ready tomorrow."
Xyzal knows that marathon training demands consistency and commitment, especially during peak allergy season. About one in four athletes suffer from allergies, and those symptoms are closely linked to sleep disruption - reducing sleep quality and limiting the restorative sleep needed for optimal performance. As the only allergy medicine designed to be taken at night, Xyzal is emphasizing the importance of relieving allergy symptoms at night to help allergy sufferers Rise Ready to train and make the most of their day. With the power of 24-hour relief that won't fade, Xyzal starts working at night to help relieve allergy symptoms during sleep, helping allergy sufferers wake up refreshed and ready for a more productive day.
"Every year, the Boston Marathon brings together athletes who have spent months preparing for their moment," said Jack Fleming, President and CEO of the Boston Athletic Association, organizer of the Boston Marathon. "Xyzal's focus on helping people wake up ready for the day ahead aligns well with the dedication and preparation that defines the marathon experience."
As part of this year's Boston Marathon sponsorship, Xyzal will be on-site throughout marathon weekend with an interactive presence at the Bank of America Boston Marathon Expo from Friday, April 17 through Sunday, April 19. Runners and fans are invited to stop by the Xyzal booth to meet Xyzal spokesperson and Peloton instructor Becs Gentry, who will be on-site to share her perspective as a marathon and ultramarathon runner who trains and competes while managing seasonal allergies.
Visitors can also explore nighttime‑themed booth elements designed to underscore the importance of relieving allergy symptoms while you sleep, enjoy complimentary samples of Xyzal Allergy 24HR, pick up branded merchandise, snap photos, and interact with Xyzal's iconic mascot, Nigel the Owl. Coupled with the Expo presence, race spectators on Monday, April 20, can cheer on "Nigel's Flock," a group of 10 influencer runners sponsored by Xyzal to showcase the power of running at your best—even during allergy season.
"As both an endurance athlete and someone who suffers from seasonal allergies, I know how disruptive allergy season can be in everyday life, let alone to a training routine," said Gentry. "Staying consistent with training routines can be more challenging during allergy season, especially when symptoms disrupt sleep. Relieving my allergies, especially overnight, helps me feel ready to take on the next day, whether I'm training, running or teaching."
