Espoo is a major suburb of Helsinki, and is both a residential community and center of some corporate offices, among them Nokia. The best place to run in Espoo is along the waterfront path, which stretches 6.3 km from the Westendin ranta (beach), west to Nuottaranta Park (next to Villa Pentry). The route is mainly along the water, with some occasionally wooded sections. There’s a dirt/gravel path most of the way, with a few road connections.
From east to west, run along the path for ~1 km to the marina/harbor area, wind around the marina and then continue west, following the water path through Nokkala, to Nuottaranta Beach in Nuottaniemi. Full out and back is 12.6 km (nearly 8 miles).
