That said it was a gravel ride. I don't think Zwift slows us down yet for having a road bike on the "gravelly" portions. They say it's in development.

Also, sweet ride area. Wish we had categorized climbs around here. All I get are the all-out 2 minute hills.

Outdoors you have to really tailor a route well to accumulate good kilojoules or uninterrupted work. Indoors I've done steady state workouts around 900KJ per hour. Outdoors my record is 820/hr last night around town. I caught a lot of green lights, hammered the downhills, and created a route I knew I could hammer.
