The Plan: //ridewithgps.com/routes/27004734 CONCORD-CISCO-NAGOG Ken-Ldr - Curt, Dom, Gene, Greg S, Jack D, Larry and Mary Kernan, Marc B, Ray Komow, Rich T, Robin Frain, Stan Kay Generally riding together. long snack and potty break at North end of Cisco - then as we were getting ready to leave, Jack discovered a flat on his rear wheel. A couple of folks examined the tire with not specific results and Jack put a new tube on and then a second stop to realign the wheel in the rear fork. On the climb up Taylor St to Liberty Square the group separated to a couple of sub groups based on speed and at the end of Arlington St by the Gray Church of the Good Shepherd, the last group of Ken and about 7 riders abandoned the left turn heading to Nagog Hill Rd and went right to Hammond St to an intersection further along Nagog Hill Rd. - thus getting ahead of the faster riders. At Rt 27 Jack split off to take his fragile bike directly home. There had been an earlier discussion of stopping to eat near Concord Market - some of the early returnees went there. The final group of 8 or so into the starting lot packed up and went home. Nonetheless a pretty good outing from a 43 degree start. I managed to keep the HR and Cadence all on the Garmin and didn't let the phone steal those devices.
