Organiser/Planner’s Report

Thank you all for venturing to the London borough of Havering to run around the eastern side of Hornchurch. We were fortunate with the weather after the torrential rain most of the day before. It was a cold night of 6 degrees and still wet in places. I apologise to all of you on the long course that had to get your feet wet immediately prior to your pint! It wasn't always like that I promise!

I decided to incorporate the river Ingrebourne on both courses as it's a very distinct feature in the area and has some well-maintained paths. Both courses visited controls along it's northern and southern banks and the river had to be crossed by all competitors at least twice.
The long course grazed the south side of Harrow lodge park, visiting the towering flats of the park hill estate, and ended up on the airfield estate, with plenty of route choice amongst some very tightly packed controls. The short course hugged hacton lane, at the beginning, and its array of garaged alleyways. Then it needed some cunning route choices while moving through the streets around Hacton Primary School.
Hope you enjoyed the challenge, as one competitor commented to me" its better than sitting at home watching tv".

The event will form part of the HAVOC/SOS Mid-Week Winter O League. Points will be awarded based on finishing times adjusted using an age/gender handicap system. Each missed or incorrect control will incur a 5-minute penalty. Best 6 results from the 10-event series will count. Anytime catch-up for some events available for 2 weeks after the event, subject to an Anytime time penalty, on MapRun. Bonus points for running on the night compared to Anytime. Full results will be emailed via RaceSignUp and published on the SOS and HAVOC websites.
You are welcome to run together as a group, but in order to be fair we ask that you keep together, as when running as a group the least advantageous handicap is applied.
100 points will be allocated to the course organiser/planner for each event planned.

If you are using MapRun then you will not need to record answers on a control card. However, if the app doesn't register your visit then you need to record the lower number on the H sign, or other reference as directed. If you are not using MapRun, then please bring a pen to mark the control card. Please also bring a map bag if wet.

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:
Hornchurch East Long
Hornchurch East 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 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.
