so i got shelled on this mornings ride and felt ****ty about it because the first half felt easy then i got dropped on the second half. turns out the first half felt easy because we had a tail wind and the sectioned averaged 26.2 mph. we turned around into a head wind and i got shelled in 6 minutes. those 6 minutes had a 29.2 average. I think the best thing I ever did was turn off the speed display on the garmin and only check it when i get home. if i had seen those speeds i would've been shelled much sooner.
