⏵ Course guide · Missouri Ozarks bluff country
The Bluffs Trail Runs winds through Echo Bluff State Park and Current River State Park near Eminence, Missouri, with a Trail Marathon, Half Marathon, 15K, 10K, and 5K all sharing the same rolling forest and cliff bluff terrain. I will walk you through the course first, then give you a pacing and fueling plan for an early May Ozarks morning. There are free calculators along the way to dial in your own numbers.
These facts come from the official RunSignup registration page. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
Every distance runs through Echo Bluff State Park and Current River State Park. The marathon repeats the half marathon course twice, while the shorter distances get their own dedicated routes.
The 15K is billed as the course that gives you "the most spectacular areas of the parks with 360 degree views of the bluffs, single track trail, colorful vegetation, and the current river." If you want the signature Bluffs scenery in a shorter distance, this is the one.
The Trail Half Marathon connects Echo Bluff State Park through Current River State Park and back, and the Trail Marathon simply runs that loop twice. Expect single track through lush rolling forest rather than one sustained climb.
Bring your own hydration vessel since this is a cupless event. The race is chip timed, and each distance follows its own color-matched course markings, so pay attention to which trail you are supposed to be on if you are running with someone doing a different distance.
Without a published vert number, plan your effort around the rolling terrain description and the shared course closure time rather than a specific climbing target.
Since the marathon repeats the half marathon course, use your first loop as a genuine data point for the second. A grade-adjusted pace target helps you hold effort consistent across the rolling bluff-country terrain rather than fading on lap two.
All distances close at 1:00 PM CDT regardless of start time. Marathon runners get 6 hours from 7:00 AM, which is comfortable for most trail runners, but confirm your pace against that fixed clock time rather than assuming distance alone determines your buffer.
⏵ Free tools to pace this course
Missouri in early May can already run warm and humid, especially through the exposed bluff sections and single track that gets direct sun through the morning.
Aim for roughly 60 to 90 grams of carbohydrate per hour on the marathon, and sodium in the 300 to 700 mg per liter range, leaning higher if humidity climbs as the morning goes on.
This is a cupless event, so plan your fluid carrying capacity in advance. The forest and river sections offer some shade relief, but do not count on it replacing a real fueling plan.

Elevation Culture does not publish an elevation gain figure for The Bluffs, but the course runs through the rolling hills and cliff bluffs of Echo Bluff and Current River State Parks in the Missouri Ozarks. A shared 1:00 PM course closure gives marathon runners 6 hours from a 7:00 AM start, generous for a course billed around scenic bluff views and single track rather than sustained mountain climbing.
A Trail Marathon, which follows the half marathon course twice, a Trail Half Marathon, a 15K, a 10K, a 5K, and a Little Bluffs 1 Mile Kids Fun Run. All distances run through Echo Bluff State Park and Current River State Park.
Early May in the Missouri Ozarks can bring warm, humid conditions, so plan fueling accordingly. Aim for roughly 60 to 90 grams of carbohydrate per hour on the marathon, and sodium in the 300 to 700 mg per liter range. This is a cupless event: bring your own hydration vessel, since no disposable cups are provided at aid stations. Build your numbers with the free ultra fueling calculator before race day.
Every distance shares the same 1:00 PM CDT course closure. That gives marathon and half marathon runners 6 hours from their 7:00 AM start, and proportionally more room for the shorter, later-starting distances.
The 15K delivers "the most spectacular areas of the parks with 360 degree views of the bluffs, single track trail, colorful vegetation, and the Current River." The 10K offers rolling hills near the Echo Bluff lodges and cabins, while the 5K is a gentler introduction to the trails. The marathon and half marathon connect Echo Bluff State Park with Current River State Park and back.
Yes. With no major elevation profile published, a generous 6 hour marathon cutoff, and a course built around scenic bluff views rather than technical climbing, this is a reasonable entry point into trail marathon distance if you have some running base already. The rolling Ozark terrain still asks more of your legs than a road marathon, so do not skip trail-specific training.
