Regional events attract participants from around the local Region, National events are high quality competitions that will attract people from far away, Major events are Major Events such as a British Championships.

Organiser/Planner’s Report

Thank you all for running in the Shenfield event on Wednesday.

We had to change the planner/organiser for this event at short notice, but I think all the controls were pretty much accurate on MapRun. I must apologise for the spuprious railway lines on the Long course map as well. These weren't on the maps I sent to the printers, so appeared somewhere in the printing process. I didn't see the maps until I was running round, so didn't notice in time to warn most of you. Hopefully it didn't affect you too much, although one small path was pretty much obscured which could have affected route choice for some of you.

As I planned these courses late, for the long I chose to use pretty long legs which afforded some route choice, rather than a higher concentration of controls which may have been more of a procession round an obvious route. Looking at the tracks, this seemed to have worked, and there was a lot of different routes taken between some of the controls. However, I think I need to ensure there is a sufficient number of controls in each area to ensure no-one takes the tactical decision to deliberately miss out some controls and take the penalty instead. I was pleased to see no one took the risk of running up the road that led straight to the finish from the final control, but there is no way through. I made the gap a bit wider on the base map to try to ensure this!

This was the last event of the series, and we will now take a break for a few weeks before the summer series kicks off towards the end of April. There are still two weeks left for people to run the courses on the "Anytime" catch up and score points for the league. Additionally, if you haven't already then there is still a chance to get a 50 points bonus for an Essex MapRun. Therefore, we can't announce the final league positions yet, but the current standings are shown on the link below.

I haven't put through all of the map runs, or the Anytime scores from Springfield yet, so there will be some amendments to these scores.

On Wednesday we had Seb Parris getting the fastest time on the Long course, and he held onto the top spot on handicap. A similar story on the short course where Colin Jackson took both the fastest time, and handicap win,

It looks like the league champions are crowned on both courses, but MapRun bonuses could still shake up the standings for the minor places. Look out for the final league table in a couple of weeks!

Thanks for running on Wednesday, and in the series as a whole. Hope you enjoyed it!

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

The courses are: Shenfield Long & Shenfield 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.
