Bike-commute day 17—gym and home

The shining, bright sky outside my cube window beckoned. Fleecy cumulus suggested a cool breeze. How much I wished work ends at 4 p.m. My co-worker Kay slipped on her jacket, said, "It's five o'clock somewhere," and headed off to her weekend

This afternoon ride was a test of how the Garmin Edge 705 treats a long period of quiet in the middle of a ride. I left the 'puter live in my bag, unable to receive GPS connections, while I worked out at the Cardinal Fitness gym.The result was OK, but it could have been better. This technique keeps all the information together in one ride, of course. The details of speed, elevation, heart rate, and cadence seem fine—without indication of the pause—when viewed with an x-axis of moving time or distance. But using the x-axis of time reveals the pause with a calm portion of a sinewave that shows a curving rise from the stopping point to resuming the ride.

This break fails to record the weight training as a contributor to the period of exercise, and, while the 705 is on but inactive with a heart monitor alarm on, the 'puter makes a frequent alert to its presence. I think for now I will create a break in the ride, and allow it to record as two separate activities.
