The Walhalla Wound Up is a 50km trail ultra and 21km and 10km trail runs organised by the Traralgon Harriers. Walhalla is a small, picturesque and historic mountain township in the Gippsland district's Baw Baw Ranges in Victoria.
The courses are over the old timber tramlines and part of the Old Moe Walhalla Train Line, which are now walking tracks, as well as some of the roads in the area. The walking tracks are very rough and narrow in some parts, as are some sections of the roads, and should be treated with caution. The roads are mainly unsealed, and generally have light traffic.
