This workout analysis shows a personal best ascent of Tunitas Creek which at the time I did not realize was a personal best, or I would have worked it harder!
Late in the season, the time was impacted by wearing medium-weight tights, carrying a jacket, partially full water bottle, bike light and tail light, as well as running a 700 X 27C front tire at 85 psi and 700 X 25C rear.

Analysis
The SRM Cannondale Hollowgram SL power meter is rated for 1% accuracy.
This was a very hard effort, but it felt relaxed as is always the case when I am well rested (having done only half workouts the two days prior, due to rain).
I paced myself steadily throughout the climb, just telling myself that a nice solid effort was all I wanted, no heroics. It was not a personal best attempt, though I had a feeling of going pretty fast. and not breathing all that hard. Ironically, best times seem to come when not aiming for my best!
As is the case for a “good day” I could not find any steep sections for the entire climb; everything felt quite easy. This is why it is worth resting— easy, free-flowing power output comes from being rested.
