Reply to "Turnaround - Point or Diameter"

With the help of Jane Parks and Chairman Gene, the Guido Brothers, established radiused turnarounds. My (probably over) simplification of this process goes something like this:
• The runners (this is not a race walk course) are going to run a half-circle around a point
• The distance around that half-circle is π x r where r is the distance from the center to the edge of the half-circle
• This is added distance as the course was measured between 2 points
• The center of the half-circle needs to be located such that the distance around the half-circle is not added to the distance between the 2 points marking the ends of the measured course
• The center of the half-circle was located π x r in the direction to make the course shorter
• The radius (r) in this is the distance from the center of the half-circle to the runners’ path
• Cones marking the half-circle turnaround were located 1-ft inside this path (r-1-ft)
• This ignores the extra distance run by leaving the centerline of the measured path to get to the edge of the half-circle. In our case we used r=7-ft, the extra distance is negligible

This is not a world, state or town class event and the race director has limited experience. Our instructions on cone locations are pretty clear. I feel that we have done our due diligence in both measuring and explaining. For the fee we were paid and what we were hired to do, we can’t be responsible for any other aspects of this event.

However, while I agree with those who favor a single point turnaround, based on what can go wrong during race day course set-up, I also think that for a 13-lap marathon, the radiused turnarounds provide a better product (CT16019JHP).

Jim Gerweck is correct, the Guido Brothers are not really brothers. In fact, over the years, there have been a total of 5 Guido Brothers, including a woman. Since the combined age of the current (and most prolific) Guido Brothers is nearly 150-yr, we probably won’t be learning to think and work in meters (or is it metres?).
