由爱莎天河学生会主导的第三届“步行马拉松”公益活动于2023年4月20日成功举办。活动以“运动+公益”为理念，鼓励学生在一小时内尽自己所能完成尽可能多的步行圈数，以步行圈数献爱心，鼓励社区成员捐赠物资。活动所募集的物资将全部捐向广州的流浪者和 "流浪者之家"的慈善组织。

The third annual "Walkathon" was successfully held on April 20, 2023, which was led by the ISA Tianhe Student Council. "Walkathon" is based on the concept of "sports + charity", encouraged students to complete as many laps as they can within one hour, and encouraged community members to donate supplies by laps for charity. All the supplies raised will be donated to homeless people in Guangzhou and the charity organisation “Homeless Love”.
