Big Hill Events is excited that their upcoming Nemisis Marathon Challenge will be hosting the 2010 Nemisis MTBA Australian MTB Marathon Championships. The event will be held on Sunday 18 April 2010 in the Pyrenees Mountain Range in Avoca, central Victoria. The Pyrenees offers some of Victoria’s best and mostly untouched riding, and is a great mountain biking destination. Riders will choose from 90km, 45km, 33km and 15km course distance options to ensure that the race appeals to elite riders, intermediate riders as well as those who are new to marathon mountain biking. The course provides an excellent mix of fire road, 4wd track, double track and single track including the Pyrenees Endurance Walk trail which is being purposefully restored for the event.
