Slow shutter speed skating

I bought tour skate blades from flea market about two years ago. Last week I bought shoes I can use them with. I also bought skis that go with the shoes as well. Today I skated 11,5 km on the lake ice. Was planning to do 15 km but I wasn't properly clothed. It was slightly above freezing but the sweater I had wasn't enough to keep me warm from the wind on the large open area on the lake.

There's nothing sharp in this pic but I didn't take many shots from places with such dark ice. It makes a more interesting background than in most other pics.
