The Lake St Clair Shadow Lake Circuit in Tasmania is a 13km trail run and part of the Tasmanian Trail Running Series.
This run starts and finishes near the front of the lake St Clair visitor centre. The course traverses the subalpine zone, climbing up to just over 1000m. The track only climbs 270m over 6.5km and then the rest of the way is down hill. The track passes through some lovely areas of subalpine rainforest and pencil pines and incorporates two bridges across the picturesque Hugel river.
