Frognerparken is widely regarded as one of the best places to run in Oslo. Located just 20–25 minutes walking distance, outside downtown, Frognerparken was historically part of the Frogner Manor. Frognerparken is entirely open to the public and easily accessible. The manor house is located in the south end of the 70 acre park, and houses the Oslo City Museum. Frogner Park has Norway’s biggest collection of roses; a total of 14,000 plants of 150 different species and a public pool & outdoor bath (summer only). Visiting the museum could be a fun, and educational, break!
Also part of Frognerparken, is Vigelandsparken, a sculpture park and museum displaying the works of Gustav Vigeland, as well as temporary exhibitions. Definitely worth quickly stopping and taking a look!
