We are going to run this event using the MapRun software.  Therefore, please, if possible, use a smartphone (or Garmin watch) and ensure you have latest version of MapRun (MapRun6) installed and the course is downloaded to your phone/watch before you arrive.

Note: All competitors will still recieve a paper map - no need to squint at your phone to see the route!

Details of how to obtain a copy of the app and how it works can be found on the HAVOC website.  There is also a HAVOC user guide there.
Download the course onto the app by clicking on ‘Select Event', and following the menu path UK > Essex

The Courses are Shenfield Long and Shenfield Short

The course will not be visible on your phone until you receive the PIN number at Registration on the night. There are no written answers required with MapRun and your result will be automatically downloaded when you finish. The full procedure will be explained at Registration.  Note, that if a control is missed then the software will show your result as Mispunch, but in the official results we will add the usual penalty for a missed or incorrect control.

If you are really unable to use MapRun, you are still welcome to take part by completing the control sheet with pen or pencil but be aware that this is a much slower method. With this approach, timing will be manually by a traditional clock, and written answers will be checked as per previous events.
