## A large marathon through Arlington and Washington

The Marine Corps Marathon is the third-largest US marathon according to the organizer and has no prize purse. The certified course starts in Arlington, crosses into Washington, and returns to the Marine Corps War Memorial. Its field size, security procedures, and timed gauntlets make logistics part of performance planning.

## Landmarks come with firm course deadlines

Runners pass Rosslyn, Georgetown, Rock Creek, the National Mall, the 14th Street Bridge, and Crystal City before returning to Arlington. Three gauntlets can divert runners who arrive late. Build the plan around sustainable progress toward those checkpoints, not a fast opening that creates a larger slowdown after mile 20.

## Arlington to the Mall: stay patient early

The opening Arlington and Rosslyn miles come before long sections in central Washington. Let effort settle on the early grades and avoid spending energy passing large groups. The flatter landmark miles give more room to establish rhythm, take fluids cleanly, and reach the first course deadlines without racing them.

## Bridge and Crystal City: protect the final effort

All runners must reach the 14th Street Bridge checkpoint at mile 20 by 1:15 p.m., then meet the Crystal City deadline. This is where controlled early pacing pays off. Run exposed bridge sections by effort, keep fueling, and save enough strength for the uphill approach to the memorial finish.

## The finish climb deserves specific practice

The organizer calls out an uphill finish at the Marine Corps War Memorial. Add short late-run hills to long-run training and practice holding posture when pace slows. The goal is not to attack every rise. Keep effort measured so the final climb is a hard closing section rather than an unexpected stop.

## Water support is frequent across the route

The race-day page lists 12 water points, Nuun at water points, a self-serve cupless station on the 14th Street Bridge, and another large water source in Crystal City. Medical aid stations appear throughout Washington. Review the final guide and practice drinking while moving through a crowded station.

## Late October normals favor cool running

Washington National Airport normals for October 25 are about 49 F for the low and 66 F for the high. Actual days can be warmer, colder, wet, or windy. Use the range for packing, then use the current forecast to set layers, fluid intake, and effort on the exposed bridge sections.
