The Laugavegur Ultra Marathon starts in Landmannalaugar which is approximately 600 meters over sea level. Hrafntinnusker is the highest point of the rout, a little less than 1100 meters over sea level.
A 500 m climb in the beginning does not sound difficult but the route is demanding and many runners make the mistake of going too fast in the beginning when climbing up to Hrafntinnusker. Experienced Laugavegur runners that use Garmin GPS measure altitude in every step have found out that the total climb is about 1900 meters and a total of 2200 meters downhill.
The run ends in Þórsmörk, about 200 meters over sea level. The following picture shows accurately the height changes on the way along with information on service available on the course.
