placette, coublevie

Did the short ride out past Placette (felt HARD in the heat!!) and back via Coublevie. I didn't want to stay out too long, so I did not take the connection to the bike path, which turned out to be a mistake: way too many cars on the Route de Grenoble. I finally got a closer look at that massive cave that you can see from the autoroute though. It looks guano-ey. There are bolted routes to the left of it though. 22 miles, 226 watts avg up placette/13 kph. I did a few sprints at the end:

5s 867 watts
30s 469
1m 310
