Event Report

Thank you all for running in the Chafford Hundred event on Wednesday.

It was pleasing to see that selecting an area from Google Maps satellite view resulted in an excellent area for courses, combining some tricky route choice in the estates, with steep climbs, and some nice off road running by the gorges and lakes.

Thanks to Graham Batty for planning the excellent courses and organising on the night. The weather stayed dry and pleasantly warm.

The winners on the night were Melanie Sirett on the short, and Seb Parris on the Long. Once handicaps are factored in, both Melanie and Seb fell to second, overtaken by Garry Parmenter and Paul Beckett.

With one event to go, David Game holds a commanding lead in the Short course standings, and Paul Beckett leads the way on the Long.

The final event is at Galleywood in a couple of weeks. Don't forget the MapRun Anytime catchup for Chafford Hundred if you want to try to better your time on the courses, or get a run round if you haven't already, and the MapRun bonus worth 100 points for attempting an Essex MapRun (not the catchup) before the end of the series.

Details of the scoring can be found at this link.

Course Information

Long Course TBC Short Course TBC Subject to final planning
Note: these will be straight line distances, optimal route will be longer.

Controls will be fire hydrants; will likely also use other park furniture or home made signs. You need to record the lower number on fire hydrants; where otherwise it will be made clear.

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 receive 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 on the HAVOC website.
Download the course onto the app by clicking on ‘Select Event', in the app, and following the menu path UK > Essex
The courses are:
TBC Long
TBC Short

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 number 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. If you are not using MapRun, then please bring a pen to mark the control card and a map bag if wet.
