A staple of many ultramarathoners preparation, for extra goodness try it at night with a friend. Wildwood Trail is the longest trail within a city in the USA.
Forest Park Conservancy data now show full length as 30.19 miles. Will update after the bridge is in as that will change the distances again slightly. (2023-still need to update this).
All season except for ice.
The map below shows the route for the run. The start is at the either near the Forestry Center or Newberry. Many now do this by meeting at Newberry and carpooling to the Forestry Center parking so that only 1 car has to pay parking, then run to Newberry. It's a bit more challenging to run the other direction so that you can finish with the hilly sections the last 6 miles from Stone House, up to Pittock Mansion, then another climb up to Washington Park.

You probably want to check the weather before heading out. Portland weather information will be adequate. This weather.com link may take you straight to weather info.
The equivalent of ranger station is the Hoyt Aboretum Visitor Center, 4000 SW Fairview Blvd.

Edited to account for movement of the Alder Trail connection at Wildwood Trail by about 0.06 mi further North from 53rd that was made ~2012, presumably over erosion concerns.Â
