EcoTrail Oslo 21 km is the best way to explore how fantastic it is to combine urban pahts with closeness to the city, nature and the sea. One of the most important goals with ecoTRAIL Oslo is to get as many as possible out in the wonderful nature that Oslo has to offer. From Fossum by the lake Bogstadvannet the path follows the beatiful Lysaker river down to Lysaker station. From Lysaker station the path follows the fjord to the finish line. We will pass the wonderful Vækerø park, Holtekilen, Bygdøy, Frognerkilen and Rådhusplassen before the race finishes by running along the marina by Akerhus Festning. Remember that everyone who finishes within the maximum time of 6 hours gets a t-shirt.
