Scottish mountain bike through routes

I've been amusing myself looking at OS mapping and trying to work out through routes based on some guide books I've acquired over a few years.
The results suggest quite a lot of possibilities for multi day outings on the mountain bike all over Scotland.
I've spent even more time making maps and putting them on a site..
Now I'm spending yet more time linking that site to streetmap.co.uk maps to get OS info, just seems to go on and on.
Keeps me amused on wet days though and on good days I'll just have to get out there and cycle them, it could be a life's work.

The past week I've got out on the road bike over a couple of nice routes.
I like the road bike at this time of year its too fast for the bugs to catch and bite me and that little extra speed keeps me cool.
Kilmacolm loop andUplawmoor loop.
Both are great runs on nice quiet roads.

Its raining outside so I guess its back to the never ending map work.
