The Marine Corps Marathon is a marathon held in Arlington, VA on October 25, 2026. With a Green Score of 8.4/10, it's one of the easier, more beginner-friendly US races. The course is mostly flat (~25 ft of gain per mile). Typical race-day weather is a cool 48°F, dew point ~42°F (10-year normal). It is a Boston-qualifying course. Entry is around $210. Marathon Compass rates every race across terrain, climate, logistics, travel, and field size so you can find the one that fits you — and build a training plan tuned to your fitness.
Typical start-line conditions (10-year history (Open-Meteo)): 48°F with a dew point of 42°F. On the temperature-plus-dew-point scale used by our pace engine, that's 90 — a 0% pace penalty. Heat should not be a factor at the Marine Corps Marathon in a typical year — race your fitness.

First marathons cost more than the entry fee — budget the whole weekend before you commit.
Net descent of ~0 ft is well under the BAA's 1,500 ft adjustment threshold. Your clock time is your application time.
Computed under the BAA's downhill rules for the 2027 qualifying window (announced Sept 2025; verified July 2026): net start-to-finish descent of 1,500–2,999 ft adds 5:00, 3,000–5,999 ft adds 10:00, and 6,000 ft or more is not accepted. Net descent here is derived from our course elevation data — the BAA's official course designation controls. Sign in to see your projected finish graded against your age-group standard and the realistic acceptance cutoff.
Entry is by lottery with roughly 32% historical acceptance — plan like you might not get in.
Plan B: if entry doesn't go your way, Ameris Bank Jacksonville Marathon (December 12, 2026, open entry, Green Score 9.2) or Space Coast Marathon (November 22, 2026, open entry, Green Score 8.9) keeps the same training block on schedule.
