Bishan-Ang Mo Kio Park, a 62-hectare city park along the banks of a former canal, is a nice place for a run in the heartland of the Bishan and Ang Mo Kio residential district in central Singapore. A series of paved trails wind through gardens and lawns. A loop of the park is ~6.4 km. Note that Marymount Rd. bisects the two sections of the park — be sure to use the connector trail at the south end. There’s a running track adjacent to Marymount Rd. Also site of a weekly parkrun, Saturdays 7:30 am. 

Longer Option: A paved multi-use path follows the Kallang River (more of a narrow canal) south of Bishan-Ang Mo Kio Park for nearly 4 km to the Pan Island Expressway (PIE).
