I love that you call that a lazy month, averaging 54 miles per ride!
It wasn't my greatest month, but then I was on vacation abroad for 11 days. I'd hoped to get my first internationally-biked miles done on that vacation, but my itinerary didn't cooperate in the end.
So, Sept. ended up as:
263.7 miles (ranking pretty poorly at 14th out of 20 biking months so far; 6th best of 2019 so far.)
10 office commutes (of 11 possible commuting days; yay 91% hit rate!)
14 days with biking (out of 19 potentially available days, ie, excluding the vacation)
(PS - no Strava or other apps/device, to tabulate elevation...)
