What is Orienteering?

Orienteering is a challenging outdoor adventure sport. The aim is to navigate between control points marked on an orienteering map and decide the best route to complete the course in the quickest time.

It does not matter how young, old or fit you are as you can choose the course that's right for you and run, jog or walk it at your own pace. It is excellent for adults wanting to shape up, add some excitement and mental challenge to their running and meet new friends. It is also ideal for families as everyone can take part at the level that's right for them and it allows children to develop independence, confidence and decision making skills.

Magnetic Fluctuation unsettles plans for JIRCs Relays 2019 at Tankersley (April Fools!)

Published Tuesday, 02 April 2019 11:22

Preparations for the JIRCs relay at Tankersley on the 29th September are well underway, but have been thrown into turmoil this week after officials encountered a rarely-witnessed phenomenon.

TankersIey is known for its infamous Bell Pits, but what is perhaps less well-known is that these were created as a result of Iron Ore mining, which took place there over hundreds of years until the 1800s. It appears that because of a combination of earth movements due to forestry works, and extreme temperature fluctuations (such as this spring) causing exfoliation, there has been a significant breakdown of the outer layers of the ancient mine workings, exposing much of the remaining iron ore deposits. The Environment Agency is aware, but have assured SYO that this poses no health risk for wildlife or other users of the area.

As a result of this, magnetic north has effectively changed. This phenomenon was discovered only a few weeks ago, and this is the first ever case recorded in orienteering history. The change has been calculated currently to be 104.19 degrees from grid north, but there are fears this figure will continue to fluctuate throughout the summer, depending upon climatic conditions.

Whilst other parts of the world, such as Australia, are more familiar with the effect of Iron Ore on compasses, there has never before been a reported problem in the UK.

A geology expert within SYO commented “Polar wander is always happening, but this far more significant… It’s similar to a total magnetic reversal, but this has never been seen on just a local level in the UK.”

It has been declared today in a statement that SYO will be “monitoring the situation closely, with hopes that the magnetic instability will settle as we move into Autumn, and that a reliable figure can be obtained”.

This clearly will have significant implications for the map of Tankersley. After careful consideration, three options as to how to overcome this issue have been put forward:

SYO are carefully considering the options as we speak (All maps © South Yorkshire Orienteers 2019)

The first is to superimpose north lines on competitors’ maps on the day of the competition. Due to the nature of waterproof paper, it has been suggested perhaps the best (and fairest) way to do this would be for athletes to draw their own north lines on the map in the start lanes – sharpies will be provided. However, this has a major impact on Tankersley’s all-important undergrowth screen, with lines running roughly perpendicular to the north lines, with huge potential for confusion.

The other option would be to establish an accurate reading for north as close to the competition date as possible, and then produce the map accordingly. But this would be a very time-consuming adjustment, potentially with just weeks to go until the competition, with significant work to undertake particularly on the area’s many bell-pit depressions & pits and the undergrowth (all of which are orientated to north on a map drawn to the ISOM 2017 standard).

It is also not clear how a re-orientated map would fit on a standard A4 page, and so to keep costs down for the event it may be that the scale will need to be altered – causing yet more work for the mapping team.

A third solution would be to re-calibrate competitors’ compasses on the day of the event. This technique has been trialled in Australia, and SILVA confirm that this causes no lasting damage to the compass. It is uncertain as to whether re-calibration complies with BOF rule 19.4.1

A final decision on re-mapping vs compass re-calibration is expected to be confirmed later in the season.

Competitors who have previously run on the area may be faced with significant navigation issues, with some suggesting it will change the ‘feel’ of navigating on the area.

Concorde Model Flying Club, based on a field adjacent to Tankersley Woods, has also been adversely affected, with club members forced to ground all planes due to magnetic interference with their radio signals.

The event organiser raised concerns just yesterday that the re-magnetism of the area could prevent the use of SIAC enabled controls for the forthcoming event, due to unknown inaccuracies. SportIdent UK are yet to comment.

SYO would like to take this opportunity to reassure juniors that the JIRCs Relays will nonetheless still go ahead, and that every effort is being made to overcome these technical difficulties.

If you have any questions regarding this matter, please do get in touch.

Convincing victory for SYO at the Compass Sport Cup Heat

Published Monday, 18 March 2019 10:12

Over 100 members of the club travelled to Sherwood Pines near Mansfield to take part in the Compass Sport Cup Heat. Thankfully the day was mostly dry and sunny and, in contrast to last weekend, there was very little mud to be found anywhere. Conditions were quick and many members raced round their courses in very swift times. 

SYO won convincingly by 97 points over DVO. We had 7 course winners - Oli, Al, Kim, Tim T, Paul B, Dom and Freya - who scored the maximum 100 points. Our other scorers were Chris W, Charlie, Jenny P, Peter G, Euan, Jill, Pete T, Imogen, Martin, Jaimie B, Amanda, Alex C, Olmo, Isabelle H, Lucy, Jenny J, Alex R & Michael. (Ian and Colin S also scored 95 points the same as our last scorer). Well done to everyone who took part, even if you didn't score, as you all helped push down the score of other  clubs.

The final is on 20th October at Pippingford Park near Crowborough in the deep south! Please put the date in your diaries - we need as many members as possible to attend so we can hold off BOK and FVO to retain our trophy!

The Spring (!) in Sheffield Weekend

Published Sunday, 17 March 2019 19:27

Control in the sleet

The name “Spring in Sheffield” clearly sealed the fate of the weather last weekend – there was no way it was ever going to be anything other than grim! Future weekends will be called “Stormy Sheffield” or “Sheffield in the depths of Winter” and the weather will be glorious! However despite the rain, sleet, snow, hailstorms and mud SYO delivered two fantastic days of competition in two very different areas. The weekend also formed part of Sheffield City Council’s Festival of the Outdoors.

Junior on the urban race

Saturday's Ponderosa urban orienteering race offered fast and furious orienteering through intricate areas of social housing and inner city parkland. The races, which attracted close to 500 entrants,  were part of the UK orienteering league and the Elite orienteering league. There were many positive comments on Colin’s tricky courses. The inclement conditions meant participants and helpers alike were very appreciative of Bill’s indoor event centre and the “SYO Junior Café” proved very popular.

Kim

The Elites were first out into the terrain with a challenging sprint race and then it was the turn of the juniors, veterans and non-elites. The men’s elite race was won by Will Gardener (OD), Dom was the highest placed SYO runner in 20th place. The women’s elite race was won by Megan Carter-Davies (MWOC) with Mary the highest placed SYO female in 4th place. In the other classes there were good results for Peter G winning the ultra vet class and Lucy taking 3rd on women’s open. SYO showed the strength of their junior section with Euan winning the junior men’s race and Matthew taking 3rd place. In the young Junior races it was a clean sweep for SYO with Robbie, James & Joseph taking 1st, 2nd & 3rd in the young junior men and Freya, Anna & Charlotte finishing 1st, 2nd & 3rd in the young junior girls.

Cat

Sunday saw the turn of the Northern Championships. The race, with close to 900 entrants, was again part of the UK and Elite orienteering leagues. We are sure everyone’s hearts sank as the sleet lashed down and they drove through the grotty industrial tracks to the swamp that constituted the assembly area. It was slightly unfortunate that the lovely tree-lined assembly had just been felled prior to the competition but, on the upside, at least the building of 800 houses had been delayed to the end of March! Fortunately helpers and participants made the best of the grim conditions and were surprisingly chipper as they went about their business.

A junior

Wharncliffe is incredibly physically and technically challenging and Oli and Jenny’s courses tested competitors to the limit. While the challenge of competing and volunteering affected many members’ results, there were still plenty of hardy SYOers that performed superby. Well done to the following:

W10A 1st Charlotte, 2nd Alice, 3rd Ella
W10B 1st Ellen
W12A 1st Freya, 3rd Anna
W14A 1st Imogen
W16B – 1st Hannah D
W18L – 1st Isobel
W35L – 2nd Rachael
W40S – 1st Susan
W45S – 1st Emily
W50L – 3rd Janet
W70L – 3rd Jill
M10A – 1st Maxwell, 3rd Lawrence
M12A – 1st James, 3rd Robbie
M12B – 1st Ben A
M16A – 3rd Euan
M16B – 1st Alfie
M40L – 1st Kim (not a mistake!)
M45L – 1st Pete T
M50L – 1st Dave P
M70L – 3rd Peter G
M75L – 1st Brian

A huge thank you to everyone who braving the horrendous conditions while helping over the weekend but particular thanks to Lucy, Bill, Oli, Jenny & Colin who fulfilled our major official roles. A big thank you also to the two controllers – Steve Kimberley and Andy Yeates.
