The Amarider 100 and 50 miler individual one-day mountain bike ultra-marathon of 160km is an annual test of MTB riders endurance. It has a super laid back vibe, but always boasts a couple of very competitive racers gunning for the top spot.
From its humble beginnings in 2009 it has grown into what is now one of the must-do-events on the mountain biking calendar. The scenery is beautiful in the Swartland during Autumn and the riding is not technical. The Ama Rider 100 miler is run every two years so anticipation is always high.
