Nobby, Not sure about that one but I witnessed Jack and another guy Dave Heine (2:25 Marathoner., 4:05 miler) do the same thing over 70k (Around 35k each) and still finished 2nd against Teams of 5. And yes ! I was in one of the Teams of 5. I was just 17 and ran my 8k in 29:30 (First time I broke 6 min miles for 5 miles).
That relay no longer exists. TRAFFIC !!!!!!.
