Are there any accounts of the lives of hemerodroi (day runners) in ancient Greece?

Factual Questions

Hi
I’m trying to find out something about the daily lives of hemerodroi/hemrodromes? in Ancient Greece.I’d prefer to focus on real people as opposed to semi-historical ones (at best) like Pheidippides. What would have been daily obstacles? Wild beats (lions, bears, wolves??) What would have been their training regimen and diet?

I look forward to your feedback.

I guess you already know the accounts by Herodot and Livius. The Hemerodromoi are mentioned in a couple of history books (for example, Julius Jüthner (1912): Hemerodromos. In: Paulys Realencyclopädie der classischen Altertumswissenschaft (RE). Band VIII,1, Stuttgart 1912, 232 ff.). I also found two articles that are available online:

Victor J. Matthews (1974) The “Hemerodromoi”: Ultra Long-Distance Running in Antiquity. In: The Classical World.
Vol. 68, No. 3 (Nov., 1974), pp. 161-169.

John Haberstroh (2012): Ancient Greek Long-Distance Runners: The Cross-Section of Athletics, Religion, and the Military.

Daily regime and diet, that of any other runner in that same climatic area before stuff from the New World became common; which in turn means, a lot of them spent more time farming than running, specially those who didn’t work in a single city. They worked either within a city or distances short enough that they wouldn’t justify paying for a mounted courier.
