Did you eat anything within the hour before the excercise ? If so, that could have been part of the rise. that is quite a rise, but tfkeel's point about meter accuracy is very important.
It took me a long time to figure out when excercise would drop my levels vs raise them and everyone is different. For me, in the morning, they usually rise after strenuous excercise.
The minute your heart starts to beat very rapidly a signal is sent to the liver that sugar will be needed for this effort and the liver releases it. Try not to go as intense quickly, slowly build up.
For me the best is to eat a little and excercise about an hour later. Lately I drink some V8 an hour before a run. I get some 'quality' carbs, it causes my levels to go up just a bit and the excercise brings it down. This also seems to improve my PP numbers. I take my low sodium V8 shot before I leave work, get home, run, then eat dinner. This provides my best PP numbers and I get more carbs in.
