Summer Series No.5 ChelmsfordThu 23 Jun

SOS/HAVOC Summer Mid-Week Series

Local level event

Explanation of Event levels

Local events are usually low key and in the 'localised' area, ideal for newcomers to try the sport and Training events are non competitive and used for training and coaching, aimed at members of the club, but they can attract people from neighbouring clubs, and are often ideal for newcomers to try the sport. 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.

Terrain type: Urban



Organiser’s Report

In looking round the area earlier on I was struck by the variety of terrain close to the town centre. Many of the participants appeared to enjoy it as well and made pleasing comments about the courses, including my determination to include the canal basin close to the end of the courses.

The two controls which caused most problems were:

1. The one sited on the southern edge of the Cathedral churchyard, many offered the one at the start of the path by the Corn Exchange.

2. The final one on the roundabout edge leading to the river path back, confused by the one on the green broadband cabinet between the two roundabouts.

Apologies to those who had trouble finding a carpark, I thought the post code and what3words plus written description of the Start/Finish area were more than adequate if read carefully.

I also prefer reworking an OO map into OCAD (the specific orienteering program) as I find the OOmaps, although accurate in their way, are often added to by various contributors, making the navigation more difficult to follow.

Please look out for the SOS urban event in 2024 which will use much of the same terrain, but hopefully also go further west along the Chelmer's tributary, the Cann, and take in more town centre and Central Park.

All the best with the remaining events of the season,

John Collyer
