⏵ Course guide · Race the train up Mount Washington
Race The Cog sends runners 2.75 miles and 3,500 feet up Mount Washington alongside the historic Cog Railway tracks, from dirt and gravel through Jacob's Ladder into the Presidential Range's boulder fields, racing the train to the 6,288-foot summit. It is short, and it is genuinely extreme. I will walk you through the course and its two entry categories first, then give you a pacing and fueling plan built for a very steep, very short effort, plus free tools to dial in your own numbers.
These facts come from the official race registration page, which notes the 2026 event was postponed from June 27 to September 13. Check the current year details, cutoffs, and aid stations before you commit.
The course follows the Cog Railway tracks the entire 2.75 miles from Marshfield Base Station to the summit of Mount Washington: dirt and gravel at the start, steeper and rockier near Jacob's Ladder, then large boulder fields through the Presidential Range on the final push to the top.
3,500 feet of gain over 2.75 miles is an extreme grade for a footrace, and the course delivers it honestly, getting harder and more technical the higher you climb rather than front-loading the easy sections. Treat this as closer to a vertical kilometer effort than a standard trail race pace.
Most entrants choose Summit-Only: finish at the top and ride the Cog train back down to the base, with a bracelet as your ticket. The Devil's Shingle Roundtripper option has you tag the summit, then turn around and run all the way back down the same 2.75 miles for 5.5 total, on the same steep, rocky terrain that made the climb hard in the first place.
The base can sit in the 70s while the summit sees snow and intense wind, sometimes on the same race day. The views across the Presidential Range are a real reward for the climb, but pack layers for genuine alpine conditions at the top regardless of what the parking lot feels like at the start.
With finish times mostly between about 1 hour and 2 hours, pacing is less about carbohydrate management and more about distributing your effort across a grade that only gets steeper.
The instinct on a short, prestigious race is to push hard from the gun. A course that only gets steeper and more technical the higher you go punishes that instinct fast. A grade-adjusted pace target for sustained climbing gives you a far more honest number than a flat-race pace, and helps you hold something in reserve for the boulder fields near the top.
If beating the elite wave train for the Delta Dental prize is a real goal, build your pacing around the specific splits that have historically beaten the train (roughly the 1:05 to 1:20 range for the fastest men), not just a general climbing pace. For most runners, the more useful goal is simply a strong, evenly paced climb to the summit.

At under an hour and a half for most finishers, this is closer to a hard race-day fueling plan than an ultra one, but the elevation and weather still matter.
A short, intense climb like this does not need an hourly fueling plan the way an ultra does. A light carbohydrate intake before the start, plus whatever you take at the Waumbek Station aid stop 0.9 miles in, is generally enough. Since this is a cupless race, bring your own small bottle or handheld rather than relying on aid station cups.
The climb is short enough that dehydration risk comes more from effort intensity and elevation than from distance. Take advantage of both aid stations (0.9 miles and the summit) and drink to the effort you are putting in, especially if the base-to-summit temperature swing catches you off guard.

It is exactly what it sounds like: a footrace against the Mount Washington Cog Railway, the historic train that climbs the Northeast's highest peak. You run 2.75 miles alongside the tracks from Marshfield Base Station to the 6,288-foot summit, with 3,500 feet of climbing, while a Cog train departs on the same schedule. Beat the elite wave's train and Delta Dental pays you $1,000. Most runners are not racing the train, they are racing the mountain, but the format gives every finisher a genuine, unusual benchmark to chase.
It is one of the steepest short races you will find: 3,500 feet of gain over 2.75 miles works out to more than 1,000 feet of climbing per mile. The course starts on dirt and gravel, gets steeper and rockier approaching a section called Jacob's Ladder, then moves into the large boulder fields that make the Presidential Range one of the most technical areas in the country. Add weather that can swing from 70s at the base to snow and intense wind at the summit, and this is genuinely extreme for its short distance. Top men finish in the 1:05 to 1:20 range and top women in the 1:15 to 1:20 range, which tells you how steep the effort is relative to the mileage.
At under an hour and a half for most finishers, fueling matters less than pacing the climb itself, but the race still stocks two aid stations, Waumbek Station at 0.9 miles and the Summit at 2.75 miles, with water, Tailwind, Coca-Cola, Ginger Ale, Mountain Dew, and snacks including fresh fruit. This is a cupless event, so bring your own hydration system, a bottle or small handheld is enough for a race this short. A small amount of caffeine or quick carbohydrate before the start is more useful here than an hourly fueling plan.
No specific numeric time cutoff is published; the event structures itself around wave starts and hourly Cog train departures rather than a hard elimination cutoff. Whichever wave and entry category you choose, Summit-Only or the Devil's Shingle Roundtripper, confirm current details on the official registration page, since format details can shift year to year.
The course follows the Cog Railway tracks the entire way. It begins on dirt and gravel, then steepens and gets rockier near Jacob's Ladder, before entering the large boulder fields typical of the Presidential Range, one of the most technical mountain areas in the country. Weather can be extreme and changes fast: temperatures in the 70s at the base are common alongside snow and intense wind at the 6,288-foot summit, so pack for genuine alpine conditions regardless of the forecast at the parking lot.
The Summit-Only entry includes a Cog train ride back down the mountain after you finish, plus a chance to learn some of the railway's history from the crew, which is the simpler option if 2.75 miles of extreme climbing is plenty for one day. The Devil's Shingle Roundtripper has you tag the summit at 2.75 miles, then run all the way back down the same trail, for 5.5 miles total. Choose the Roundtripper only if you are confident descending steep, rocky, technical terrain on tired legs, since the boulder fields that made the climb hard do not get any easier heading down.
