Extreme sugar jump after hard work

I am newly diagnosed and am trying to put exercise in to help.

One thing that happened yesterday though spooks me. I spent an hour working removing snow. I was good and sweaty when I came back in. I know I had been at 110 sugar before I started. When I checked after I was at 199 sugar. After working out regular will this jump go away. I came down real quick about 20 minutes after I stopped. Dropped back down to 140 and I felt super tired. Will this happen often if I do a long workout, and is it something I should be concerned about?
