The Race

The race starts and finishes at Logaland, our info center.

The race takes you through Reykholtsdalur and Lundareykjadalur, two beautiful agriculturual valleys filled with grass fields, salmon rivers and sheep. The climb out of Lundareykjadalur is called Uxahryggir, it is a approx 15 km (9 mi) climb of 300 m (980 ft). Many waterfalls can be seen on this part.

The Kaldidalur highland road is next. It can only be described as magnificent, set in a desolate post-glacial surroundings. The road is a bit rougher than up till now. The highest point of Kaldidalur is at approx 700 m (2,300 ft) and the view is great in all directions.

The glacier Eiríksjökull can be seen from there as well as the former glacier Ok. The descent down to Húsafell takes you through contrasting nature, starting in the post glacial desert and ending in the low forest and clear rivers of Húsafell.

From there you ride through some beautiful agricultural valleys of Hvítársíða. The great glacial river Hvítá runs down this valley and can be great inspiration for wild riding.
