Training objective: 2-4 hour tempo ride with the heart rate between 140-150 bpm's and the cadence running at 75-85 rpm's. Against the wind the last 2 hours. I couldn't resist a few sprints, which of course got the heart rate up a bit higher than the target, but I was feeling strong, so what the heck. :) Will take it easier tomorrow - probably ~100 km's and I'll stick to the heart rate/cadence objectives the whole time - I promise! I used the lap/split function but only at the 2 hour mark and then again at 4 hours 15 minutes. Except for leaving the city, the 1st 2 hours felt pretty fast. Either a family of chirping canaries were following me or it's time for a good clean of the chain and cassette and re-lube. And maybe even a service in case the bearings in the crank are starting to go... hmmm, maybe it was canaries. Seriously, though, if I need to take my bike in for a major service I'm going to be out of action for at least a few days (shops are closed Sundays
