Rode alone departing at 9 am. My plan was to do at least 35 miles. In the back of my mind was the number 50. Weather was cloudy and overcast initially but there were a few bits of sun as I got deeper into the ride. There was a a mild wind pushing NB. After leaving the lakefront I rode for a couple of miles with a group of 3 riders from the North Side on a beer run to Lake Bluff. I declined their invitation since I was pushing my limits to do 50 miles. I turned around on Sheridan just past the light house. I had to work against the wind SB. I stoped on the lake front of NU's campus to take a few shots of sail boats. I saw Stephon downtown just north of Randolph and chatted for a few minutes. The break was timely since I was beginning to struggle. The last 10 miles were challenging. Based on my fitness level 35 miles would have been about right but I got it done. I am sure I will feel it tomorrow.
