We've started running recently, with the slightly ridiculous goal of
doing a marathon up a mountain in almost exactly a year's time.
(Idiots.)
All the stuff you read about running for beginners says "Stay away
from the hills! Do nice easy runs on the flat!". They talk about
keeping to a conversational pace, or running so that you take one
in-and-out breath for eight steps, or something like that. Holland
would be perfect for beginner runners -- nothing very steep, and
certainly no long hills to wear your legs out.
