What makes a marathon good for beginners?

Flat terrain (less than ~40 ft of climb per mile), cool and dry race-morning weather, a large field with official pacers, and open or easy entry. Our first-timer score weights terrain, climate, and field support most heavily.

Should my first marathon be a big-city race or a small one?

Bigger fields generally help first-timers: more pacers to run with, more crowd support, and aid stations every mile or two. The trade-off is travel cost and lottery entry for the majors.

The easiest marathons for your first one

Your first marathon should be a race that helps you finish, not one that fights you.
