Organiser/Planner’s Report

Thank you all for running in the Brentwood Central street O last night. This was event 8 in the series and the weather was a bit warmer at last! Gary Chandler and Chris Prince won the Short and Long respectively, hold onto those wins when handicaps are applied, and lead their respective league tables for the series so far!

Two events to go in the series - Springfield (SOS) and Shenfield (HAVOC). The courses from last night will be on MapRun in the next day or so if you wanted another shot, or didn't get to run last night and wanted to secure points for the league. They will be open until the next event in the series for that, and then available for a MapRun bonus, along with all the other Essex MapRuns after that. Remember to grab your 50 point MapRun bonus by attempting any of the Essex courses before the end of the series and then letting me know.

Details of the scoring can be found at this link

Map / Terrain

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.

Details of how to obtain a copy of the app and how it works can be found here.

There is also a HAVOC user guide here.

Download the course onto the app by clicking on ‘Select Event', in the app, and following the menu path UK > Essex > Brentwood Central

The course map will not be visible on your phone until you receive the PIN number at Registration on the night. (Note – you do not need the PIN nuber to run using a Garmin watch). 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. Please ensure you notify the organiser that you have finished, so that safety checks can be completed.

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.

Course Information

These are direct line distances – optimal route will be longer, approximately 8.0 km long and 5.3 km short. Start & Finish will be at the front door of the pub on Hart Street.
