Year 26 for me to help raise funds for diabetes research. Warm, humid but windless start for the Metric course roll @ 8:00 AM. Mix of trails, neighborhoods and quiet roads from Pottawatomie Park to Lily Lake, after which the course opened up onto familiar roads to Maple Park, Sugar Grove and Kaneland. South winds were a bear heading in that direction, but gave a great push on return. Very warm and humid until the black clouds and lightening started to move in around noon from the NW. Almost finished dry, but ~6 miles from the end the heavens opened up and I detoured to an unscheduled gas station stop in Wasco. Twenty minutes later, skies cleared and was able to return to the start. Great day in the saddle, considering I was able to raise >$3,500 this year (and my bike got a wash).
