Training Log Archive: Jagge

Easy jogging, I could use my normal gait - first time since knee injury at Jukola.

night control test, Jäkel map.

About the ongoing map scale discussion.

Here is clips from ISOM 2000:

"due to limitations in printing technology the final map symbol dimensions may vary up to +/- 5%."

Boulders, boulder fields: "it is permitted to enlarge this symbol by 20%".

Boulder cluster: "it is permitted to enlarge this symbol by 25%".

Contours: "Absolute height accuracy is of less importance. It is permissible to alter the height of a contour slightly if this will improve the representation of a feature. This deviation should not exceed 25%of the contour interval"

So, we area allowed to vary the size/scale of lots of stuff by about 10..25%. How would it work if simply add the map itself to the list of allowed to enlarge. Like this:

Map scale for long is 15 000 and for middle 10 000. Due to terrain character and limitations in printing technology the final map scale may vary 20%, for long 12500 to 15000 and for middle 7500 to 10 000.

Would it all soon end up with unreadable maps with scales 7500 and 12500, maps full of details? Or would it end happily, maps becoming more legible, mappers doing mapping as they do today, course planners getting room for common sense after seeing how our printers actually behave, O community still claiming maps scale for long is 15 000 and for middle 10 000 being just enlarged 15 000 map and leaving us old ISOM purist farts happy?

Mapper can't know in advance how the map will look like - one usually don't know the printer one will be use or will it be offset map. Fine tuning legibility by editing/re-mapping/redrawing map is much more expensive than changing scale a little bit.

And. splitting hairs here - paper shrinks. I am sure 15 000 map is usually not exactly 15 000, it may vary 0.001 % or something. So scale is variable already.

Event: Yökuppi 12 Asikkala Majuanmäki
 

Map needs a name. Something cool, like Swampfox's map "Plutonic pleasures". I am usually not good at this, but I think I have a good candidate. "Yökyöpelin jäkäläyllätys". Describes the area well, cool and easy to pronounce and remember - for international runners too I guess. What do you think, would it do?

C • Easy... 13

One hour of head lamp mapping, bare rocks :


It was kind of strange you actually could do mapping in the dark. GPS cursor was spot on all the time, cliffs and stones were just where they should, just draw grey color every time you felt like seeing something greyish on the ground - bare rock mapping, Finnish style :)

C • I like grey on the map. :) 9

C • That is the way 3

I wonder why we should use standard "long" tags or no tags. What wrong with these short ones?

Today two hours more mapping:

C • Land forms 7

GPS mapping, still mainly working on path network.

1.5h mapping with Topias in backpack carrier. mostly paths and boulders by those paths. Good to have extra pair of eyes. This was daytime mapping. Most of the mapping so far has been done at night with headlamp. I wonder will it be any good for night O if part of it is mapped in daylight.

Instructions are poor, but I hope with try & error based learning someone may be able to make it work.

Some screen shots gps cursor - menus and stuff:

Event: 25manna
 

25manna, 5th leg. Limping slowly with sore knee. map:

I guess my biggest time loss happened on the way to #2, I had to stop and tell Tuxi our location :)

maybe it is just me, but I's say the map was pretty bad (for excessive form line use). In some places form line interval was about 80 cm. Maybe map it was fine for some purposse, like berry picking, and excellent by some standards, but not by IOF's standards. Of course best will do fine with maps like this, but it's not the point. It is like having javelin final at Olympics and instead of standard javelins you give athletes basket of potatoes. Best javelin throwers will throw potatoes well for sure, but those who has learned the technique to trow well the standard javelin will not have advantage they deserve. In ISOM we have fixed contour interval and there is only on level of form lines between contours (2.5m), so mapper just can't map everything, mapper has to simplify. And athletes must learn the skills to navigate with such maps. And racing with these maps is called orienteering. You can have races with 25manna style map, but I'd say it's slightly something else. But like I said maybe it is just me and everyone else is happy with the map. I found it kind of boring and annoying. It's more fun to run with ISOM maps, you need to use later variety of O techniques, not just pick form lines. I wonder why they used normal contours too, they cold have used form lines only.

Anyway, now I'll take month off from running, hopefully knee will be better.

C • 40 seconds... 2

2 km warm-up, then 2 km at max speed. Today it was 4:17. With normal stride max pace was 5:00, but when I ran with short skiing like steps, knees bent a lot all the time, butt low, I could accelerate a bit. It felt odd and some muscles are sore now. I guess I'll get injured if i run like that a lot. But I guess my body will survive a short leg at 25manna.

C • speed 7
