I often wonder this, watching one (the Commonwealth one is on at the moment). Presumably the course (for record setting purposes etc) has to be precisely 26 miles 385 yards, which must be quite hard to get exactly right, if you've got a certain landmark in mind for start and finish? I mean you could stick a route into a routeplanner programme, but do they rely on the accuracy of those?
I always imagine someone having to walk the proposed course with one of those wheely measurement things you see surveyors using, getting to the end, checking it to read "26 miles, 500 yards" and thinking "Bugger! Start again ..."
