The Convict 100 is one of Australia's most challenging MTB marathon races following the historic Convict Trail through the Dharug and Yengo National Parks.  The course features a mix of fast fire trail, technical rock gardens, rocky descents and spectacular ridgeline views in the Macdonald River Valley.  The start/finish is in the village of St Albans outside the 186 yr old stone pub "Settlers Arms Inn".
