User "Where's My Burrito?" has completed a thesis-level analysis of a rollerblading sequence in D2: The Mighty Ducks over at Battle of Cali. Using Google Maps, his knowledge of Minneapolis, and the above video as reference, Mr. Burrito estimates that the sequence had the kids skating a technical 43 miles, which would likely wind even the real-life NHL Anaheim Ducks. That's over 12 miles further than Rocky ran in Rocky II.
When it comes to pointing out continuity errors in children's movies, it doesn't get much better than this.
