Lost the plot

My Runkeeper has lost the plot - I set off to do a ten mile training run and after 5 minutes she told me I had run over 2 miles. I reset it and began again from where I was but the same thing happened so I left it to see what would happen. Well, according to her I was running an average of 3 minute miles and ran 30.93 miles in under 2 hours - fabulous!! Not sure if the thundery weather is affecting it or the lanes are making her confused about where I am - I did a good long run anyway and tried to work out my distance via my normal split times. Think I did my ten miles!
