The original Illuminator route and longest distance – a serious physical and mental challenge. Runners only please!

Come back to measure yourself against previous years' efforts or jump in at the deep end if you want to test yourself with a hilly route that passes through the heart of Glen Tanar's ancient forest and follows the beautiful Water of Allachy and Water of Tanar.
