Left, Right, or Straight: Leg Analysis #19

 

 Left, Right, or Straight: Leg Analysis #19

A landscape of this type can be seen in many European countries, such as Italy, Spain, or Portugal, as well as in Turkey. It also resembles Australia. However, this is in North America (USA, California). It’s a vast continent where you can encounter a great variety of landscapes.

 Leg 5-6 presented in this analysis is from the C10 distance of the competition CalOFests Stage 3 NRE Long, which took place on 2023-07-19.




The route choice is significantly influenced by the amount of climb. Moreover, a climb that follows a gentle road is much easier than one on a steep slope. Therefore, this factor should also be considered.

The right-hand route seems too complicated and physically demanding. The easier approach to the control point is not worth it. (The red sectons represent areas with a climb).



After excluding the right-hand route, we are left to consider "straight" or "left" options.

The straight route is also not exactly straight and has some lengthening. Also, it has more climbs than the left option.


The left route seems the most optimal. To simplify the execution of the route, the leg can be broken down into smaller tasks by placing 'intermediate control points' in the saddles along the main roads. Now, it's easier to handle the task. All that remains is to decide on the'micro route choice' for the intermediate legs 5-A and A-B. 

The micro route choice largely depends on the athlete's physical condition, as well as the state of the ground cover and soil.

The approach from B to 6 will be the same for everyone, whether on the left or straight route.


If we compare the left and straight routes, we can see that they converge at saddle B, and the distance of these routes is approximately the same.

Therefore, the deciding factor will be the climb. On the left route, it's about 130 meters, of which the first 60 meters are along a gentle road and last section too. On the right route, it's about 150 meters, and mainly this section runs across a slope that is quite steep.


Unfortunately, the leaders of this distance did not upload their GPS tracks, so we cannot see the actual routes and the differences between the various ones.

  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...
