Event Description
This evening metrogaine competition explores the 4.75 square-kilometer area of SW Portland west of the Stonehenge radio/TV tower. You have 1 or 2 hours to find as many controls as possible in any order while running or walking. Bring a watch to help avoid a point penalty for finishing late. Each solo competitor or team uses the MapRun® phone app for timing and verification of controls found.
You may do your course as an individual or as part of a team, but if you are part of a team, you must remain with your team at all times while competing.
Your placement in the results is dependent on the total number of points that you earn for controls found. Tie scores on the same course are broken by the overall times. The point value of each control is determined by the tens digit on the control number (for example, control 38 is worth 30 points).
After you finish your event, enjoy no-host food and drinks at the Casa Colima Mexican Restaurant and Cantina while comparing your course with others.
This is an almost all-weather event that can be postponed if serious heat wave conditions exist. In the event of a postponement, we will announce any scheduling changes to everyone who has registered for this event.
