Looking at the course maps and timing, is anyone else concerned about 10K front-runners being stuck behind the slower 5K walkers for the second half of the race? The courses overlap, which wouldn't at all be an issue if the two races were held at different times, but by the time the last group of 5k folks start, it will be getting fairly close to the 10k start time. And if the tail end of the 5k are the walkers (which is appropriate, don't get me wrong, I think the 5k walkers should be given all the time they need and deserve, and its equally unfair to them to have faster runners from a different race bumping into and zooming around them), the serious 10k runners will catch up fairly quickly even with the longer course.
Is RunDisney going to have volunteers at each split directing runners back and forth across the two courses? Are they really thinking they will be able to clear the 5k course before the 10k starts? Will the finish line be a mix-up of both sets of runners finishing and getting medals together? Any thoughts?
