Late aft'n ride w/ gentle winds and reasonable warmth (for mid winter!), great for a road bike ride . Avg spd 14.3 mph (15.9 mph last time) at 10 mile marker (Howe Park). ( Avg H/R ? bpm - still need chest sensor battery replace ). Avg speed build-up as ride progressed: Knox Trail Jr High entrance road (1/4 mile into the route) 16.6 mph (20.6 mph last time) ; top of first big Ash St hill (at 2 wx vanes) 8.5 mph (last time it was 8.6 mph); at end of Ash St 10.2 mph (last time 11.0 mph); corner of E Charlton & Bacon Hill Rd 11.6 mph (last time 13.4 mph); E Charlton & Old Spencer Rd (town line) ? mph (last time 13.6 mph); end of Old Spencer Rd (at Rt 31) 12.6 mph, (no more green/red light today, bridge raising project completed, back to old Stop sign), ( last time 14.0 mph ) ; bottom of downhill trough on N Sturbridge Rd (just before Osgood Rd) 13.8 mph (last time 15.2 mph); corner of Briarcliff Ln & Bacon Hill Rd near railroad underpass 13.8 mph (last time 15.4 mph); end of Cranberry Meadow Rd at railroad overpass ? mph; Howe Park, at turn onto Lyford Rd uphill just before railroad overpass- 14.3 mph (last time 15.9 mph). Wx conditions: sunny w/ gentle E winds at 4 mph, air temp 44 F , dew pt 24 F . Clothing: three layers lower, 6 layers upper ( 3 (outer) of 6 unzipped ), 1 earband under helmet. Time to rotate front and rear tires, as rear tire is picking up tiny slivers of glass/ quartz sand particles, which will work their way into the tube if not caught in time by inspection and removed. No roadside snow banks to speak of at all this winter so far, and thus no messy snow melt on roads to deal with on warmer days!
