BRUTAL. SPECTACULAR.

The Hounslow Classic is a weekend of gnarly and spectacular trail racing which encompasses the best that Blackheath, and the Grose Valley Wilderness has to offer. 

Synonymous with brutal climbs, steep technical terrain and jaw dropping valleys, runners traverse along the tops of sheer sandstone cliffs, dive deep into canyon trails passing through ancient landscapes, and ascend rocky peaks with 360 degree views of the chiselled Grose Valley.
