Dylan Efron has revealed that he never runs without a lightweight belt bag for his phone, especially for runs over two miles. The "Traitors" star shared his fitness essentials during a Sun Cruiser run club event, noting that he is a self-trained marathoner who ran the New York City Marathon in 2025 after training in less than a month despite not having run at all that year. Efron described his go-to pouch as "very lightweight" and "very small," barely fitting his phone and cards. Efron also shared other fitness staples, including New Balance 1080s for daily mileage and Nike shoes for race day. He emphasized the importance of ChapStick, face lotion from SkinCeuticals, and lightweight tinted sunscreen from EltaMD and La Roche-Posay, noting that he spends as much time in the sun as possible.
