March in Shanghai was awash with spring and blooming tulips. At 7:30 a.m. on March 22, the 2026 Chinese Athletics Association 10km Elite Series Shanghai Jing'an and Jing'an ∑ 10km Elite Run fired off at Daning Park. Thousands of runners wove through the flower-lined course, immersing themselves in speed and excitement while experiencing the district's interlaced urban charms—its waterways, green corridors, commercial hubs, and high-tech innovation zones. As an official event partner, Suzhou Creek Bay–based grin, a New Zealand professional natural oral-care brand, participated deeply with the theme "Brush Thoroughly, Run Joyfully", and its parent‑child sports carnival became a highlight, cleverly linking oral-care habits with sports and life styles and injecting smiles and vitality into the spring race.
The race was organized by the Chinese Athletics Association, the Shanghai Jing'an District Bureau of Sports, and the Daning Production-Life-Ecology Integrated Innovation Zone Administrative Committee. After registration opened, the event attracted 38,021 runners from 25 countries and regions, including 35,734 entrants in the 10 km category and 2,287 in the family category. Nearly 5,000 athletes took part—a sign that this spring, more and more people are choosing to devote time to a healthier, more upbeat lifestyle.
On the course, runners threaded their way between Daning Park's sea of tulips and Jing'an's bustling commercial hubs, taking in the unique scenery where springtime light blends with urban life. In the family category, hand‑in‑hand scenes were everywhere, with parents slowing their pace to encourage children as they completed the springtime running challenge together.
As an oral‑care brand advocating a natural, healthy, and sustainable lifestyle, grin injected playful energy into the event by highlighting a refreshing, thorough brushing experience. At the parent‑child run, it turned the course into a colorful, child‑friendly playground—its vivid visual design acting like a mobile "family toothbrushing wonderland" that instantly evoked innocence and curiosity. Families released energy together while the on‑site activation subtly reinforced the link between daily dental care and a healthier way of life.
At the event, grin's newly launched three‑stage, age‑specific children's toothbrush and its toothbrushing buddy series holders drew widespread attention. Staff introduced the scientific concept of age‑appropriate dental care to participating families and explained that selecting progressively tailored toothbrushes to match a child's oral characteristics at each developmental stage is the most precise and effective way to protect their teeth. Meanwhile, partner Shanghai Am-Sino Healthcare warmly distributed gift bags on site to thank attendees for their trust.
At the interactive booth, grin's signature DINO mascot charmed attendees with its adorable presence, warmly waving to every finisher as they crossed the line. Whether elite runners celebrating personal bests or parent‑child pairs sprinting in together, participants of all ages stopped to pose alongside DINO, capturing bright, post‑race smiles on camera.
To help the scientific approach to dental care truly become part of everyday life, grin also offered interactive giveaways at its booth: Finishers who scanned a QR code on site could collect professional oral‑care products. The thoughtful "Smile Guardian" gesture quickly ignited runners' enthusiasm, with many eager to take the "fresh" care home.
In addition, grin installed a finish‑line photo wall where finishers proudly hoisted their hard‑earned medals and faced the camera with their most confident, relaxed smiles. From elite runners setting new personal bests to brave first‑time 10 km finishers, and then to parent‑child pairs crossing the line arm in arm, every group paused before the wall to make a uniquely memorable highlight moment.
In 2021, grin's China general manager, Liu Lipeng, and his project team embarked on their entrepreneurial journey in Suzhou Creek Bay, Jing'an. From the very start, Jing'an District departments moved quickly to provide the company with efficient, precise, and attentive tailored support. Today, grin not only advances oral‑care product and industry innovation through technological R&D, but also plays an active role in Jing'an's mass‑fitness initiatives, contributing to the promotion and development of the district's healthy‑living ethos.
grin is committed to offering healthy, safe, and eco‑friendly oral‑care products to consumers worldwide. Its toothpaste is crafted from carefully selected New Zealand native ingredients, using 100% plant‑derived extracts to replace chemicals that may pose health risks, and has won favor among users in New Zealand, China, and beyond. Science‑driven, the brand conducts long‑term clinical research in partnership with Massey University labs in New Zealand and the Hospital of Stomatology, Wuhan University in China, while advancing oral‑health public welfare: Its 2018 "Share a grin" large-scale children's health initiative has benefited more than 400,000 children across China, the U.S., Australia, and New Zealand. grin also launched a ten‑for‑one empty‑tube recycling program and has strengthened cooperation with international environmental, children’s education, and charity organizations to support environmental protection and public health.
