2026 Rocket City Marathon - Dec 13 Countdown

Q: When is the 2026 Rocket City Marathon and what time does it start?

The 2026 Rocket City Marathon is on Sunday, December 13, 2026, with the full marathon starting at 7:00 a.m. CT in downtown Huntsville, Alabama at the Von Braun Center. An optional early start at 6:00 a.m. is available for runners who expect to finish in 6 to 7 hours. The half marathon goes off at 9:00 a.m. that Sunday, and the 10K, 5K and 1-mile fun run are held the day before on Saturday, December 12.

Q: How much elevation does the Rocket City Marathon course have?

The course is fast but gently rolling rather than dead flat, with roughly 670 feet (about 203 m) of total climb over the 26.2 miles and no major hills. Because total elevation loss is well under Boston's 1,500-foot limit, your finish time counts toward Boston qualifying with no downhill adjustment. Preview your splits on a rolling course with our elevation profile tool.

Q: What is the time limit for the Rocket City Marathon?

The standard course time limit is 6 hours from the 7:00 a.m. gun (about a 13:44 per mile pace). Runners who need more time can take the 6:00 a.m. early start, which allows up to 7 hours to finish; early starters must keep at least a 16:02 per mile pace and reach the halfway point by 10:00 a.m. Plan your splits with our pace calculator to stay ahead of the cutoff.

Q: Why is it called the Rocket City Marathon?

Huntsville is nicknamed the "Rocket City" because it is home to NASA's Marshall Space Flight Center, where Wernher von Braun's team developed the Saturn V rocket that launched the Apollo missions to the Moon. The course passes the US Space &amp; Rocket Center, which displays a full-size Saturn V, and the start/finish is at the Von Braun Center downtown. First run in 1977, the 2026 race is the event's 50th-anniversary running.

Q: How do I register for the 2026 Rocket City Marathon?

Registration is handled online through the Huntsville Track Club at rocketcitymarathon.run, with English-language sign-up that is straightforward for international runners. Entry is tiered by date — it starts around $85 for early registration and rises in steps to about $155 by race week — so signing up early saves money. There is no qualifying time required to enter.

Q: What is the weather like for the Rocket City Marathon?

Mid-December in Huntsville is typically cool and dry — a race-morning low near 35°F (2°C) warming to a high around 50°F (10°C). It is excellent fast-running weather; dress for a chilly corral with gloves and a throwaway layer, then shed as you warm up. Occasional frosty starts are common, so plan a warm bag-check outfit for after the finish.

Q: Where should I stay for the Rocket City Marathon?

Most runners stay in downtown Huntsville near the Von Braun Center start/finish, which keeps you within walking distance of the expo, start corral and post-race area at Big Spring Park. Downtown also puts you close to dining and the Space &amp; Rocket Center. Huntsville International Airport (HSV) is about 15 minutes from downtown, with larger hubs in Nashville and Atlanta within driving range.

Course Profile

Course Type	Loop / out-and-back through the city
Elevation Gain	203m
Terrain	Road (paved city streets and tree-lined neighborhoods throughout)
Profile	A fast, gently rolling road course through Huntsville — the home of NASA's Marshall Space Flight Center, where the Apollo program's Saturn V rocket was built. The single-loop route starts and finishes downtown at the Von Braun Center and winds past Big Spring Park, the Huntsville Botanical Garden and the US Space & Rocket Center (home of the towering Saturn V display) before returning through quiet tree-lined neighborhoods. It is not pancake-flat — expect gentle, runnable rollers totaling roughly 670 feet (about 203 m) of climb over 26.2 miles — but with no big hills, cool December air and a USATF-certified, accurately measured layout, it has been one of the South's most reliable PR and Boston-qualifier courses since 1977. About 8.6% of finishers qualified for Boston in 2025 (7.4% in 2024). The 2026 race marks the event's 50th-anniversary running.
