Used to work in Stirling. There are cracking runs round the back of golf course and across dual carriage way towards cambusbarron, also castle and spingkerse industrial estate which is lit. There is a 3 mile and 6 mile run if i recall in a loop, nice scenery. Just miss Raplock in your runs! There are some others too, i'll look.
Mapmyrun.com is excellent or http://gb.mapometer.com/en/ and google earth can pick up some quality runs
I like your use of Tangerine! (I'm a hopeless arab)
