Training objective: Group ride and see what the guys are doing, but hard efforts if I can. Any number of hours but very hard effort at with the heart rate at 150 bpm's rate and the cadence at 65-75 rpm's for the last 1-2 hours. Very few group rides now that it's a bit chilly out (there was evidence of salt on some of the bike paths), so it was a solo ride. As I never have any idea where I am or how long it'll be before I get back (never mind "the last 1-2 hours"!), I gave it the gas pretty well the whole way - against the wind for the 1st 3/4 - only slowing down in the urban areas. Heart rate was a bit lower than target, but I wasn't taking it easy, I promise! Pretty fun fall ride today - 54 Strava "achievements" including 1 KOM (over a bridge), 22 PR's and one top 7 trophy for a 2.5 km segment - - and it wasn't wet, which is always a bonus! :)
