Growing better at long distance cycling, make effort to drink every 30 minutes. Wahoo gps maybe malfunctioning - alerts directions/turns late or redirect away from destination! Found myself circling neighborhoods a few times before I gave up with gps. Major Taylor NB to Damen to 47th St to Halsted St smooth sailing. Halsted to Milwaukee Ave stop Stan’s Donuts. Early in this ride ample opportunity for breaks, restaurants & every type of cuisine imaginable. Milwaukee to Damen to Lincoln to North branch trail head. North Branch trail smooth, but not fully marked in areas. Skokie Lagoons to Botanical Gardens crowded winding paths of fitness enthusiasts of all ages & activities. Once on path restrooms were scarce and no water fountains except at information center In Botanical Gardens. Green Bay Trail also wasn’t marked well - no water or rest rooms and a challenging climb. Sheridan Road was fun, filled with fast cyclists & traffic giving right of way & space. Bahá’í Temple, Northwestern University and Evanston area good for cycling. Roads are well maintained & people seem friendly. Lakefront Trail crowded & chaotic able to refill water & rest in shade. A few detours adds to confusion for bike lanes as well as beach goers casually walking in bike lane. Should’ve been 83 miles ended at 90.
