Just how flat is your commute?
 

Some of us measure elevations in inches or millimeters. My 7.8 mile commute works out to 92 inch elevation gain per mile.

I could avoid the 24’ descent by not using the trail under the interstate highway.

Anyone able to beat my KOM of 92 inches per mile?

I live in the foothills East of San Diego, and commute to the shore. 550 foot loss/gain. Glad that the elevation gain is after work!
