Yes, the long legs were good - but there could have been a few more short legs in the mining detail, particularly at the end of the course when you are tired. That makes the best long distance style courses in my opinion.
Does seem silly not to use the mining detail when it's a goldmining map - would be like using contour features for control sites on Kooyoora :)
A good long course has a mix of leg lengths, and centres on route choice. It should therefore have some long legs with marco route choice, some medium length legs with route choice, and also some short legs to break up the course.
Jenny... Colin Walker (who dislikes granite) once set us an event on Kooyoora using a contour only map. It was really really challenging navigation.
Chris - I particularly like the IOF's definition of a control simply being the means of ending a leg, not that I always subscribe to this...
Bruce, changing to middle distance style right at the end of a classic length course is creeping into common practice but that doesn't necessarily mean it's best practice.
To argue against my initial position- the Sprint, Middle and Long rules are just three possibly extreme stereotypes of an orienteering course designed to maximise differences between three world championship races in one week. I just learned that am event I set last year has been named Course of the Year in Victoria. I was quite surprised by this as the event didn't conform to any of the three definitions of a course. It was sluice mining terrain and park terrain. The map was 1:5,000. The expected winning time was 30 minutes. The emphasis was on fine navigation and many short legs. A doubter would call it control picking. It finished with four or five legs in the park, Not sure what this is- sprint middle? The main point is that it was probably the best way to use an unusual and difficult slice of terrain to maximise the enjoyment of the competitors. Perhaps this is what Bruce is talking about. If one travels to Chewton from Melbourne, perhaps its reasonable to expect to have some fine navigation in the complex sections of the map. Maybe we should advertise the style of course setting for our local events so distant travellers can make an informed decision before hopping into the car.
