The preamble to the next heatwave (HW4) today was in the high eighties with high humidity and nary a breeze. Yet, Grahak Cunningham fashioned a 72.99 mile day to take back nearly six and a half miles for his lead over Sarvagata Ukrainsky. The latter went past the 2000 mile split for the second time in his brief multi day career( 2000 miles = 28 days +10:00:00). Five of the weary warriors went past 60 miles on a very difficult breathing day.Only late evening thunderstorms returned a little cool air to the mix.
