Riding early in the day is the best during the hot days of summer. Even before 7AM there were three cyclists descending as I rode up. The only downside is that as soon as the sun comes up, the warm air rises above the plains and the cooler air in the mountains rushes downhill to replace it, so you deal with a headwind at that hour.
Word has it that Jeffco is making an uphill bicycle lane on Mount Vernon Canyon.
