Author of the PL XYZ (name is still to be defined, also I'm extremely late compared to what I was expecting, and it's quite possible there's at least one year of work before I can release something).
At marathon my time is 5:30, that's far from a world record. I plan longer trails (60 km seems feasible for now) after I have made public the version 0.0 of the language.
