Race Day Weather

Average Temperature4.9°C / 41°F
Humidity47%
Wind21.4 km/h
Rain Chance7%
Typical ConditionsCold, dry, sunny early-January high-desert morning — around 39 degrees F (4 degrees C) at the 8:00 a.m. start at 3,900 ft of altitude, climbing toward the mid-50s degrees F by midday

What to Prepare: January in the Chihuahuan Desert is cold at the gun but reliably dry and bright — expect a near-freezing start around 39 degrees F (4 degrees C) and almost no rain (about a 7 percent chance). Wear throwaway gloves and a long-sleeve you can shed once the sun is up, and don't be fooled by the 3,900 ft altitude — it is high enough to dry you out, so keep drinking even though it feels cool.

Wind Impact on Race Day

Wind at 21.4 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

Course Profile

Course TypeFlat out-and-back
Elevation Gain53m
TerrainRoad and paved path (with a short hard-packed gravel section), flat
ProfileOne of the flattest road marathons in the Southwest. The course is a USATF-certified out-and-back that starts and finishes on the track inside Field of Dreams Stadium in Las Cruces, so you literally cross the finish line on a stadium oval. From there it runs almost entirely on paved path and road through the Mesilla Valley pecan orchards, with the jagged Organ Mountains rising to the east and the Rio Grande corridor nearby. The elevation profile is essentially flat — about +53 m / 174 ft of gain across the whole 26.2 miles (low point ~3,862 ft, high point ~3,906 ft), with a matching gentle loss, so there are no real hills, just long, fast, exposed straights. A short section runs on hard-packed gravel pathway rather than asphalt. Because it sits at roughly 3,900 ft of altitude, the thin, dry air can sting the legs of sea-level runners late in the race even though the grade never bites. It is a genuine Boston qualifier — flat, certified, with cool desert weather — making it a strong, low-key pick for a winter BQ attempt or a first marathon where you want the course, not the hills, to be the easy part.

Frequently Asked Questions

When is the 2027 State 47 Las Cruces Marathon and what time does it start?

The 2027 State 47 Las Cruces Marathon is on Saturday, January 9, 2027. The full marathon starts at 8:00 a.m. Mountain Time on the track at Field of Dreams Stadium. There is also an optional Early Bird start at 7:00 a.m. (advance sign-up and access code required) that gives slower runners an extra hour on course before the 3:00 p.m. course closure.

Is the Las Cruces Marathon course really flat?

Yes — it is one of the flattest marathons in the Southwest. The USATF-certified out-and-back has only about +53 m (174 ft) of total elevation gain over 26.2 miles, with the course sitting between roughly 3,862 and 3,906 ft. There are no hills to speak of, just long, exposed straights through the pecan orchards. The main twist is altitude, not gradient: at ~3,900 ft the dry, thin air can wear on sea-level runners even on a pancake-flat profile.

Is the Las Cruces Marathon a Boston qualifier?

Yes. The course is USATF-certified and a Boston qualifier, so a qualifying time here counts toward Boston Marathon entry. The combination of a flat profile, cool dry January weather and a small, uncrowded field makes it a quietly effective BQ option — just budget a little extra effort for the altitude. Check the standard you need on the Boston qualifying calculator.

What is the course time limit?

The course closes at 3:00 p.m., which is a 7-hour limit from the 8:00 a.m. start. Runners who need more time can take the optional 7:00 a.m. Early Bird start, effectively giving an 8-hour window to the same 3:00 p.m. cutoff. The 7-hour standard limit works out to roughly a 16:00 per mile (9:56 per km) pace, so it is achievable for most walkers and run-walkers.

What is the scenery like along the course?

The race runs through the Mesilla Valley pecan orchards with the dramatic, jagged Organ Mountains rising to the east and the Rio Grande corridor close by. Most of it is on paved path and road, with a short hard-packed gravel section. It is a scenic high-desert tour rather than a city race, so expect open, quiet stretches with mountain views rather than wall-to-wall crowds. Las Cruces also has reliably sunny, dry January weather, which adds to the appeal.

How big is the Las Cruces Marathon and how do I register?

It is a small, low-key marathon — only about 160 runners finished the full in 2026 — so it never feels crowded and entry rarely sells out far in advance. Registration is handled online through Race Roster, with no lottery; prices rise the closer you get to race day, so signing up early is cheaper. The weekend also includes a USATF-certified half marathon, a relay and shorter distances.

Does the altitude in Las Cruces affect the race?

It can, mildly. The course sits at about 3,900 ft (1,190 m) — high enough that sea-level runners may notice slightly harder breathing and faster dehydration, especially in the dry desert air, but low enough that it is not true high-altitude running. Most runners feel little impact early and a touch more effort in the closing miles. Arriving a day or two ahead and keeping up with fluids helps; it does not make the flat course slow, just worth respecting.
