The Senior Games times are now posted, confirming what I already know: my 5k time trial preparation needs to be better. In the 5k I finished 12th of 33 riders overall. In the 10k, I finished 6th of 37 riders. Of the 37 riders, one was in my age group, so only 4 riders in the younger crowd were faster. My speed was actually faster in the 10k.
In the Natchez Trace ride, since we were tourists, my heart rate hardly ever topped 110 and a lot of times I saw it in the 85 bpm range. As a change of pace, I would drop to the largest gear and pedal along at 50 rpm.
Sunday on the 360 ride (42 miles) with Evelyn, I had to extend myself to keep up (again), and with the wind and hills, couldn't hold a high rpm, but the heart rate stayed mostly in the 130s for almost three hours.
Yesterday on my 30 mile ride in excellent weather, I concentrated on keeping high rpms. Most of the time it was 80 and higher, a lot of which exceeded 85. I finished with an average of 80, my highest ever, and my time was the fastest ever. Time is not necessarily a reflection of the ride, in that traffic and red lights come into play, but the average speed also was fastest.
Unfortunately my tt bike doesn't have a cadence counter, but I'll try a lower gear on a practice run to see what that does to the time.
