Timing system

The   SPORTident  timing system will be used for all days, with SI Air+ mode activated. Users of SI Air+ timing chips do not need to place their timing chips in contact with the timing unit on the stake or trestle at each control, or at the Finish point. All other SPORTident timing chips (including those rented from the organisers) will function in the normal way – they must be placed in the hole in the timing unit at each control, and at the Finish point. HE competitors should note that as the Day 3 course has 30 controls they must either use a SPORTident timing chip that can retain at least 30 times or hire a timing chip for the Day 3 race.

Timing chip hire. If, as part of your entry fee, you have paid to rent a SPORTident timing chip, you should collect this from the information point at the Event Centre or Arena before the first race that you have entered.

Please leave a deposit of either EUR 50 or an identity document. This should be placed in the brown envelope provided – please write your name and mobile phone contact number on the outside of the envelope, and seal it, before passing the envelope back to the event official for safe keeping.

Please return your rented SPORTident timing chip after each race to the same location that you collected it from. The event official will in exchange return your sealed brown envelope.

Start times

All pre-entrants, except the H/D10- and SE, SD, MM, LD classes, will have start times allocated before the event.

The full list of start times will be published on helga-o.com/start on the evening of Saturday 14 June. Please check that your entry details are correct. If there are any problems or queries regarding the start list, please contact orga2025@o2lux.org as soon as you can. It will not be possible to change your start times during the weekend, so please do contact us beforehand.

Start procedure

Number bibs (“dossards”) are not being used.

For each of the three races, if you have pre-entered and are using the SPORTident timing chip that you entered with, you do not need to register at the Event Centre or Arena. Once you are ready to run, you can proceed directly to the Start.

At the Start, the procedure will be the same as is generally in use at larger events. Please “clear” and “check”, using the timing units in the pre-start area.

Loose control descriptions (IOF standard symbols only) for all courses will be available after the -2 minute line.

You will be asked to stand at your map issue point after crossing the -1 minute line, but you may not pick up your map until instructed to do so. Your timing for the race starts as soon as the start signal is given – there is no timing control at the start point or start kite (i.e., no “punching start”). On Days 2 and 3, there is a 150 metre run out to the start kite.

The procedure is different for the H/D10- and SE, SD, MM, LD classes. These participants may start whenever they are ready, at any time before the last start time as shown in that day’s event programme. They will be helped through the Start area by an official, and must then use their SPORTident timing chip at the timing control for these courses, to register the precise time at which they start.

At the Start, please do not leave any litter. Please put any drinks bottles in the litter sacks provided in the pre-start area.

There will be no possibility to change your start time if you arrive late at the Start – irrespective of when you actually start, your result will be calculated based on the start time shown in the start list. The Start officials will do their best to get you started as soon as possible, but you will not be allowed to start at the same time as another runner on your course.

Plan of the start area

Results and prizes

Live results will be available during each race, and afterwards, at https://helga-o.com/webres/ On Days 2 and 3 the results will also be displayed on large screens at the Arena.

Livelox will be available after each race.

Each day’s final results are for a separate race. The results of the three races will be combined to give overall results for the weekend.

Prizes will be awarded to the competitors in each class with the best three overall results for the weekend.

Day 1 - Luxembourg Ville - Extended Sprint

The Event Centre is located at Salle Victor Hugo, 62 avenue Victor Hugo, 1750 Limpertsberg Luxembourg Ville (49.620847, 6.122112).

At the request of the City authorities, please do not park at or nearby the Event Centre..

Nearest tram stop (Theater) to Event Centre - 400 metres.

Event Centre to Start - flat, 1,200 metres, allow 5 extra minutes to cross major roads.

The courses pass along streets that will be busy with foot traffic. Please show care, courtesy, and respect to all pedestrians at all times. If you do have any accident or collision, however minor, please report this at download.

Please go to the Event Centre after finishing your race, and download. Once you have started, you must download, even if you do not complete the course.

The finish timing point will be removed as soon as the courses close. The Event Centre closes at 21:00.

Timetable

  • 16.30 - Event Centre opens
  • 18.00 - First start time
  • ~19.20 - Last start time
  • 20.30 - Courses close, and the finish timing point removed.
  • 21:00 - Event Centre closes, all competitors must have reported to download by then.

Travel to the Event Centre

The city is a busy place on a Friday evening, and the large “Glacis” car park near the Event Centre will be closed on the evening of the event, as it is to be used as the venue for the City Sounds festival, meaning that other parking facilities will be in high demand. Most on-street parking is reserved for residents’ use.

The City Authorities have therefore asked participants travelling to the race by car to park at any of the “P&R” Park and Ride or other parking facilities and use the tram or other public transport or walk to get to the Event Centre.

All public transport in Luxembourg (trains, trams, and buses) is free to use, and no ticketing or other proof of entitlement systems are used. Just get on and ride!

The brown line on the map below shows the route of Tram Route 1 (currently the only tram route in Luxembourg City). The nearest tram stop to the Event Centre is “Theater”.

The Event Centre is 400 metres north from the “Theater” tram stop - walk past the Best Western hotel and up avenue Victor Hugo, and the Event Centre is on the right, You will see red and white tapes.

Suggested parking facilities

Real-time information of the availability of spaces in covered car parks, and further information about car parking around the city, is available at https://www.vdl.lu/en/getting-around/by-car/parkings-and-pr

Race overview map

It is a 1,200 metre walk to the Start - follow the red and white tapes back towards the Theater tram stop and continue towards the old city centre. Two very busy roads must be crossed at traffic lights - you may have to wait, allow extra time. The route to the Start diverges from the route returning from the Finish in the public park after the road crossings - bear right to the Start. Pre-start and warm-up are in the small park Robert Brasseur (49.61291, 6.13184).

On the course

Controls will be hung from trestles, with timing units securely attached to the top of the trestle.

In some areas, controls are placed quite close together. Please check that the control number shown on the timing unit at the control is the number of the control you are looking for, as shown on your control descriptions.

It is strictly forbidden to use any public lifts during the race.

It is essential that all out of bounds areas marked with purple hatching or shading on the map are strictly respected. Any failure to observe out of bounds areas would be likely to imperil any future use of the area for orienteering.

During summer 2025, there are many temporary features across the city centre that are part of the LUGA (Luxembourg Urban Garden) artistic and horticultural exhibition. These have been mapped using the IOF standard symbol most appropriate to the individual feature concerned (building, small monument, other prominent man-made feature).

Safety

A number of busy roads are marked with purple hatching on the map, as out of bounds. You must not cross these roads, except where gaps in the out of bounds hatching are shown on the map – typically these will be at traffic lights or formal pedestrian crossings. You may however use the pavements beside these roads.

Marshals will be present to assist and protect orienteers crossing the busier roads. Please take great care here and any instructions the marshal gives.

Please obey the Luxembourg “code de la route” at all times, especially when crossing roads with traffic lights, where red lights must be respected. This is a condition imposed by the City authorities for being allowed to hold this race.

Be mindful that there will be many tourists and other non-orienteers in the competition area, especially in the Haute Ville. The streets will be busy here, especially if the weather is good.

Please do not run through the outside seating areas of restaurants and bars. Many of these are marked on the map as small out of bounds areas, but the mapper cannot be sure to have identified all such areas.

There are some high cliffs and very steep drops in some parts of the competition area used by the courses for adults. The courses have been planned to keep you away from danger, so if you find yourself near the edge, please step back!

At the Finish

The Finish point will be indicated solely by a large banner, and two timing units on trestles.

There will be no water or other liquids provided in cups or bottles at the Finish.

Please proceed to the Event Centre to download. The return route begins with a ride in the panoramic Pfaffenthal elevator. On exiting the lift, follow the red and white tapes and you will soon rejoin the route that you took to the Start.

Thanks

Luxembourg Orienteering wishes to thank the Ville de Luxembourg city authorities for granting permission to run in the city centre, for making the Event Centre hall available, and for much other practical help and guidance. The Day 1 race could not take place without their support.

In some areas, controls are placed quite close together. Please check that the control number shown on the timing unit at the control is the number of the control you are looking for, as shown on your control descriptions.

It is essential that all out of bounds areas marked with purple hatching on the map are strictly respected. Any failure to observe out of bounds areas would be likely to imperil any future use of the area for orienteering.

The forest is frequently used by hunters. Structures they have built are mapped as follows.

Mapped as T (ISOM 2017-2 symbol 525 - small tower) Not marked on the map (too many of them!).

The terrain - Planner’s notes

Day 2

Saturday's Middle Distance will take place in a very open part of the forest with gentle relief and is therefore fast.

The northern part is a beech forest, typical of the Anlier Forest, quite easily traversable but with visibility most often limited to 50 metres. The terrain has numerous charcoal burning pits, small streams, ditches and marshes, requiring careful reading. The southern part is a rolling forest of oaks and fir trees, typical of the Ardennes.

The courses twist in all directions and you will have to take particular care - anticipate your direction when leaving the controls!

Day 3

The last stage promises surprises in the final results. This stage is the longest but also the most technical. The relief will not be a problem, rather the alternation of different types of woodland, with less obvious penetrability than the day before, suggesting some route choices. The forest is rich in point details such as charcoal burning pits, rootstocks, knolls, small marshes, and small thickets, and in linear details such as streams, wet ditches, linear marshes, more or less clear vegetation boundaries, and a few paths that only the younger classes will want to use.

If you have fallen a little behind your competitors during the first two stages, don't worry, you will have plenty of opportunity to catch up, provided you are well in contact with the map... so go carefully!

Have fun!
