I participate (and help organize) the Time Trial Series at Lowes Motor Speedway in Charlotte, NC. We actually have two events this month with the second one the last week in June.
Below is a graph of my TT from last night's event. I had an "okay" time but it was 10 seconds higher than my PR. My time last night was about what I was expecting as most of my riding has been for the distance events rather than for a TT. After Monday, maybe I'll start doing some 20 mile TT training to get better prepared for the 10 milers at the track.
Observations from last night's data:
The Heart Rate stayed up there pretty good-averaged around 176 I believe with a max of 183. I'm okay with that.
Average speed was 25.4 mph with Max of 30.1 and a minimum of 22.
Note the drop in speed the last 3 miles or so.
While the track is relatively "flat" there is a slight rise in elevation on the front stretch and a touch of headwind-hence the speed differences.
It's not on this graph but my average cadence was 87-that is using a 53 front chain ring with a 12-23 cassette.
