utility downloaded all 2136 workouts.  The lion kingdom used dailymile from 2014 until it was disabled in June 2018.  

For the 1st time, the annual mileage could be plotted.  It definitely peaked in 2016.  That was the last year any humans of lion age were still running.  It was quite motivating to race against the humans, but all animals eventually outlive humans.  2017 was the achilles tendinitis.  2018 was the metatarsal.  Pushing the limits, trying new exercises & new footwear did it.
