Biking in Helsinki-Espoo-Vantaa region

Roughly 50km round trip as follows: - Louhela, Vantaa (start) - Leppävaara - Tapiola - Lauttasaari - Kaivopuisto - Pasila - Pikku huopalahti (water bottle refill) - Hämeenlinnantie up to Kaivoksela - Louhela (finish) Unfortunately the camera battery ran out during the first half of the trip :( I managed to recharge the battery some, but it ran out afterwards as well. At least now I know approximately how long the battery and charging will last, so I can better plan the trips :D
