Maridalsalpene - 37 controls (04-07-2017)

My longest training run in several years, 2 hours 55 minutes:

This particular part of Nordmarka contains all the steepest hill in the Oslo area, Guttorm's route is a magnificent trip past all the best viewpoints on the map.

We were 7 people who met up at Skar parking by 17:00, we started just 5 minutes later and made it back by 20:00 after 13+ km and 700+ m ascent, all of it in fabulous conditions.
