D'Emonda. Mostly sunny but hazy with the Canadian wildfires, warm, 77-80 degrees, East winds @ 7-10 mph with 14 mph gusts. A nice day but smoke bothered my eyes over the whole ride. No other riders spotted. Good route from Sycamore Forest Preserve up to Burlington and out East past Plato Center, all on old familiar roads. Decided to do an interval ride with the fairly strong headwinds heading East. First time riding the D'Emonda in a while, rode like a champ. Good workout: 15-20 second spinups during 10 min. warmup 5 X 6 30/30's HI/HC 1 X 5 60/60's HI/LC 1 X 5 120/60's HI/LC Series of TT efforts on the return, various distances, mostly HI/HC. Raised my ride average from 14,7 mph at the turnaround in Plato, up to 16,2 mph.
