Left, Right, or Straight? Leg Analysis #15

 

 Left, Right, or Straight? Leg Analysis #15

On May 31st 2024, a long-distance race was held as part of the training camp for the Youth European Championships in Poland.

The courses offered competitors many typical legs for this type of terrain.

One of them was leg 3–4 for M18 and M16 (the same as leg 2–3 for D18 and D16).

This leg offered a range of three classic route options:

  • The shortest, but with two 30-metre climbs;

  • The middle-length option (left), with one 30-metre climb (+200 metres in distance);

  • The longest option (right), with only 15 metres of climb (+350 metres in distance).

On the Livelox website, only a few GPS tracks from competitors are available, and we don’t know their fitness level or how much effort they put into running this leg.

However, it’s still clear that — among competitors of similar speed — the straight route lost to the right-hand option by approximately 30 seconds on average.
See the GPS tracks from the D18 class.


The left-hand route appears to be about equal to, or possibly better than, the right-hand option.
However, there is very limited information available — only a few competitors chose that route, just two in total.
See the GPS tracks from the M18 class.

The left-hand route was less predictable in the middle section, where accurate execution of the path transition was crucial.
It also presented a more difficult approach to the control compared to the right-hand route.

Several mistakes were observed on the control approach from both the straight and left-hand routes.
See the GPS tracks from the M16 class.


On the right-hand route, no mistakes were made during the approach stage — one could say it was almost elementary.

Conclusion: On legs like 3–4, choosing a direct route can lead to losses rather than gains — especially at the beginning of a long-distance race.

Note: Some time after publication, public access to the full GPS data from this competition was restricted.

  Case Study #4 Case: You ran onto a narrow ride slightly below its end and are unsure which of several similar rides you are on.   Solution: In this situation, the relief profile can assist us. Even if the rides themselves appear similar, the relief profile along each ride differs , providing valuable clues for accurate positioning. This approach is discussed in Chapter 3 ( Using All the Indicators for Confident Positioning ) of the book Planning Reliable Routes . It demonstrates that relief can be used not only when we are uncertain about our current location , but also proactively during route planning . By analysing the map in advance, we can identify segments where linear features intersect with relief forms , creating distinct and easily recognisable points. These can serve as reliable positioning features . Additionally, flat areas and transitions between slopes and level terrain can also support effective location verification. (Example taken from my book Plann...

New o-book is coming this fall!

  New O-Book Coming This Fall! Confident Orienteering: A Systematic Approach to Minimising Errors Book 1: Fundamentals was released in October 2023 and has already been translated into seven languages , alongside the original English edition. With 8 chapters and 140 pages, it introduced the core concepts of the author's navigation system — and I’m still amazed at how warmly it was received by orienteers around the world. 🌍 As we continued working on the next part of this practical guide, it became clear that the project had grown into something much bigger — not least because of the sheer number of examples and illustrations included throughout (around 250 in total!). To make the material easier to absorb, we’re now leaning towards splitting it into two volumes , each with its own clear focus. This isn’t a final decision yet, and even the titles below are working titles — but right now, this structure feels like the most reader-friendly option: 📖 Book 2 (working title...

The Road to JWOC 2026, #2 (Long Distance)

  The Road to JWOC 2026, #2 (Long Distance) Short  Leg 1: what to do In the previous post in this series, we identified—based on the terrain characteristics and extensive experience from many previous competitions in this area—that a short first leg with complex navigation is highly likely. In this post, we focus on what exactly to do in such a situation. Let us begin by explaining why we are specifically discussing short first legs . If the first leg is longer , it will most likely intersect paths , as this terrain is full of paths of different types . In that case, an athlete has several safety options : – choosing a detour along paths; – or navigating less precisely on a bearing , deliberately aiming off early to hit a path and then restoring exact position while running along it. https://www.livelox.com/Viewer/JVM-test-lang/D20?classId=392774&live=false&tab=player In such scenarios, the initial nervousness and uncertainty at the beginning of the co...
