Yuma Territorial Marathon training plan: course, start dates, and plan options
Yuma, AZJanuary 30, 2027
Ninety eight people finished the Yuma Territorial Marathon in 2026, and that was a big year: the four editions before it finished between 40 and 53 runners. It starts at 7 a.m. at the Cocopah Resort and Casino south of Yuma and runs an out and back on the shoulder of a highway through the farmland of the lower Colorado River valley in late January.

That is a very specific kind of race day. You will not find a pack to sit in, there is no crowd, and the road is straight and flat between roughly 73 and 147 feet. Everything about your finish time is going to come from your own pacing, and the race is put on by Caballeros de Yuma, a local charitable group, which tells you what sort of event it is.

The course: a highway shoulder out and back through the valley
The Yuma Territorial Marathon is a USATF certified out and back that the organizers describe as having minimal elevation change, run on the shoulder of a highway. There is about 74 feet of downhill in the opening stretch and an equivalent uphill near the finish, and the course sits between roughly 73 and 147 feet the whole way.
That symmetry is worth thinking about. The gentle drop you get for free in the first mile is a gentle climb you pay for in the last, at exactly the point where a marathon is least interested in negotiating.
Start is 7 a.m. at the Cocopah Resort and Casino in Somerton, and the marathon shares the morning with shorter races and a team relay. With a field this size, expect to run long stretches with nobody in sight.
How to train for the Yuma Territorial Marathon
Train the Yuma Territorial Marathon for solitude and for a climate you probably do not live in. With fewer than a hundred marathon finishers and a flat highway shoulder for a course, there is no pack, no pacer to follow and no terrain change to break the rhythm. The skill this race demands is generating and holding your own pace for three to five hours with nothing external helping.
So make solo goal pace running a formal part of the plan, not an accident. Do at least four long runs alone, no music, on the flattest and least interesting road you can find, and practice the specific act of checking your pace and correcting it every couple of miles. That is the exact task race day will hand you.
The climate is the other half. Late January in the lower Colorado valley averages a high near 70F with very dry air, and most people training for this race are running through a northern winter. Dry heat raises your fluid loss while making it feel like you are barely sweating, so build a drinking schedule and follow it by clock rather than by thirst. If you can find a few warm, dry afternoons late in your block, use them.
Save something for the closing climb. Stride matches you to one of 14 marathon plans built on the most proven training methodologies in the sport, then maps every week from today to that 7 a.m. desert start.
Getting in
This race does not sell out. Online entry runs through RunSignup, and the organizers also take registrations in person on Friday evening from 4 to 8 p.m. and on race morning up to an hour before the 7 a.m. start, which is rare enough to be worth knowing. Every finisher gets a technical shirt and a medal, and cash prizes go to the top three men and women in the marathon.
Where does the Yuma Territorial Marathon get hard?
The final stretch, where the roughly 74 feet you dropped in the opening mile has to be climbed back after twenty five miles run largely alone.
What is the weather like at the Yuma Territorial Marathon?
Late January around Yuma averages a high near 70F and a low near 47F, with the dry air typical of the lower Colorado River valley. No reliable start line temperature is published for this race, so plan for a cool morning that warms quickly and finish conditions well above what your winter training accustomed you to. Dry air hides sweat loss, so drink on a schedule.
Is the Yuma Territorial Marathon a good Boston qualifier?
The course is USATF certified and the organizers state it qualifies runners for Boston entry. Qualifying rates are modest and volatile in a field this small, with about 5.1 percent of finishers running a qualifying time in 2026 and 4.2 percent in 2025, up from those levels in earlier years. With under 100 finishers, a single fast year moves the percentage a lot, so read the trend loosely.
Is the Yuma Territorial Marathon a good first marathon?
It suits a first timer who wants a quiet, low pressure race and does not suit one who needs a crowd. The course is flat and the atmosphere is friendly, but no course time limit is published and support on a highway shoulder is thinner than at a city race. Confirm the cutoff with the organizers before you enter if you expect to be out past five hours.
Yuma Territorial Marathon questions, answered.
How small is the Yuma Territorial Marathon?
Very small. It had 98 marathon finishers in 2026, and between 40 and 53 in each of the four years before that. You will run long stretches alone with no crowd and no pace group. For runners who dislike crowded starts and jostling for tangents, that is the appeal rather than the drawback.
Is the Yuma Territorial Marathon course flat?
Nearly. It is an out and back on a highway shoulder sitting between about 73 and 147 feet, which the organizers describe as minimal elevation change. There is roughly 74 feet of descent in the opening stretch and the same amount of climbing near the finish, which is the one part worth pacing for.
What is the weather like for the Yuma marathon in January?
Mild and very dry. Late January in the Yuma area averages a high near 70F and a low near 47F. That is comfortable racing weather for most runners, but the dry desert air increases fluid loss without the sensation of heavy sweating, so drink to a schedule rather than waiting until you feel thirsty.
Can you qualify for Boston at Yuma Territorial?
Yes, the course is USATF certified and the organizers state it qualifies for Boston entry. About 5.1 percent of finishers ran a qualifying time in 2026 and 4.2 percent in 2025. With a field under 100, those percentages move sharply year to year, so judge the course on its flat profile rather than the rate.
