Event Description
This metrogaine competition explores a new housing community that has interesting routes between neighborhoods and through various parks. You have 1 or 2 hours to find as many controls as possible in any order. Watch your time carefully, as there is a point penalty for finishing late. Each solo competitor or team must use 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 are broken by time on the course. The point value of each control is determined by the tens or hundreds digit on the control number (for example, control 38 is worth 30 points and control 116 is worth 100 points).
