Left, Right, or Straight: Leg Analysis #21

 

Left, Right, or Straight: Leg Analysis #21

Today we will take a look at Leg 5–6 from the M18 Long Distance course at the  Novembertävlingarna, lång event (23.11.2025)

Organising club
Tullinge SK (Sweden)

In the M18 class, the most successful route choices used a less distinct path running between the hills.

In general, the approach to the control could be planned either contouring around the hillside or crossing over the top. This decision largely influenced the entire route choice on this leg.


Interestingly, both of these approaches were used by the fastest runners on this leg (Carl-Meijer Axelsson and Jonathan Enarsson) — and both produced very similar results.

The athlete who placed 3rd on this leg - Ivar Nordberg (and eventually 3rd overall) most likely made a mistake. After reaching the top of the hill, he deviated down toward the open field — a move that doesn't seem justified. Most likely, he lost direction while descending the slope.


This leg also appeared on the M21 Long Distance course.

Here, the leg winner (Simon Hector)— who also won the entire course — ran close to the leg line, choosing the top-of-the-hill route.

However, if we look at the athlete who placed 4th on the leg and eventually 5th overall (Christian Foley) , he chose the same indistinct path that the M18 leaders used (also approaching over the hill).

When comparing athlete speeds: he finished 13:43 behind the winner, over a 10 km course, which means he was running about 1 minute 20 seconds per km slower on average.

This suggests that on Leg 5–6 (920 m), a "normal" time loss would have been around 1 minute or slightly more.
Yet in reality, he lost only 31 seconds — which indicates that using the path was a very effective route choice.

That said, this type of leg rarely allows for big gains from one route over another — but a poorly executed direct route can result in significant time loss, as shown by several of the slower M18 tracks.


It’s also important to keep in mind that open forest varies in quality. The most accurate decisions are often made during the race, when the athlete sees the actual terrain conditions — including ground characteristics like rocky surfaces or heather.

Finally, it should be noted that forest and ground quality may vary along the leg and cannot always be evaluated as consistent throughout the route.

Make the most of the off-season between 2025 and 2026 — review your navigation system if you're not satisfied with its current quality.
The Confident Orienteering book series -  a systematic approach to minimising errors - will definitely help you with that.

The most detailed analysis of navigation in orienteering:

Book 1: Fundamentals — Understand the causes of mistakes and develop strategies to reduce them.
Book 2: Planning Reliable Routes — Learn how to plan routes that account for a wide range of potential errors.

  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...
