Alpine lake hike + swim
There is a local alpine lake that I want to swim. It is a tough 3 hour hike in, and is only 6 km long. There are no boats or water craft available, so there would be no support. if I do the swim, I would take my feeds in a Myfloat dry bag. So the question is, can I consider this a legitimate marathon swim, given the two 6 km legs, and taking along the dry bag? The answer to this question will not be a determining factor for doing the swim, but I am curious!
