A fantasy track in Finland. The track is somewhat worn and not well maintained and as such the track surface is pretty bumpy and patched up. The track is fast flowing and traditional and is well suited for most cars. But the challenging old school nature makes it also tricky for the modern fast cars.

The track comes in three variations. The Full version is the full length track with the "old" loop making the track length 5.268 kilometers or 3.27 miles. The fast corners are challenging in all kinds of cars and the twistier bits are fun in all categories as well. The shortest Club layout is 3.442 km or 2.14 miles. This layout is optimal for single seaters and touring cars. Then there is the Trophy layout which leaves out the tighter corners of the full layout making its length little shorter at 4.4 kilometers or 2.73 miles. This layout is ideal for historic race cars and any fast cars.

There is a wet version of all of the layouts. In the dry there is little more grip on the racing line but in the wet it is advisable to experiment as there is little more grip off the racing line.

The track download also comes with some career events. You can find these in the career section of the game. There is a mix of hotlap events, races and quick races. The hotlap events have very difficult gold lap time targets. If you want those gold times you really need to work for them. The races have adjustable opponent strength which means you can tune the event difficulty to your liking.

The track also support night racing through the SOL addon and shaders patches in content manager. You need to have these installed to be able to use these features but these addons are purely optional and not required to be able to enjoy the track and career events.

The track is now 1.0. This means that the track has all the features I've planned to add to it. New developments with the base game and common addons like SOL, content manager and shaders patch could mean more features could be added later. Naturally if there are issues with the track a patch will be made to address those issues.

Thanks to ac community for support and creating tools and documentation. Thanks to my amazing beta testers roq and andy riches. Thanks to Leonardo Ratafiá for additional track cameras and testing. Thanks to LilSki for writing excellent tutorials and guides and testing. Thanks mascot for testing and his work on adboards.

If you wish to support me financially I recommend instead supporting the following people and projects (not in any order) : Assetto Corsa Content Manager, Custom Shader Patch, SOL and LilSki.

I want to marry this track, that is how much I love it! It has everything, ups, downs, lefts, rights. No 2 corners are alike. Really works well with vintage cars.

Awesome work! Beautiful layout + execution. The more they shave off every bump from the Nordschleife, the more your track will gain. Love it. Thank you very much.

It's a bit like a compact mini-Nordschleife. Very entertaining with its bumps and hills.

Hands down my new favorite circuit. The trophy layout is amazing in modern GT3 cars. It kind of reminds me of Zandvoort. This mod is a must have!

This track is very well done, difficult (especially on the wet), but rewarding.
