Add My Race Review


The Trionium Greensand is an extremly tough race with hills, hills, and then more hills - including Leith Hill, Somerset Hill, Holmbury Hill, Reyards Hill and Winterfold Hill.

The Course

The marathon boasts 5200 ft of ascent and descent. The half marathon is less harsh but still difficult turning around at Leith Hill.
