Double up

When I lived in Melbourne a decade ago, I used to go for long evening runs along St Kilda Beach and up to the Royal Botanic Gardens. At the time, I had no responsibilities whatsoever (except maybe finishing that PhD thing I was working on) so it was essentially a different world. Still, with both kids taking a lunch nap, I decided to turn right at the end of the lake and go for two full rounds. 1602 kcal later it is now time for a late lunch...
