Texas fall running comes with one small catch: sometimes Texas forgets it is fall.
A September 5K in the Hill Country can still feel a whole lot like summer. By October, mornings become more promising. Then November arrives and suddenly runners who spent months negotiating with heat, humidity and 6 a.m. alarm clocks remember why they like doing this.
The good news is that the Texas Hill Country 5K calendar for fall 2026 gives you plenty of reasons to keep training.
You can race through historic Gruene, tackle rocky trails near Lake Travis, run under the stars in Junction, make an Oktoberfest weekend out of Fredericksburg or finish the season with a Thanksgiving race in Boerne or Kerrville.
And no, you do not have to be chasing a podium or personal record to belong at any of them.
If putting a race on the calendar helps you train consistently for the next six or eight weeks, that alone can make it worth registering.

Race information and registration prices below reflect organizer information available August 21, 2026. Schedules, prices, policies and availability can change, so confirm the latest information with the organizer before registering or traveling.
Gruene 10K/5K/Kids K — New Braunfels
Saturday, September 12, 2026
If you want one race that feels unmistakably Hill Country, Gruene is hard to beat.
The 5K starts at 8:00 a.m. near Gruene Hall, with the event also offering a 10K and Kids Fun Run. The organizer lists the 5K as a run/walk and gives participants 1 hour and 15 minutes to complete the course before roads reopen. The current adult 5K price is $50 through August 26, increasing as race day approaches.
This is one of my favorite types of races to recommend to recreational runners because the race is only part of the day. Gruene gives you somewhere worth hanging around afterward instead of immediately walking back to the car and heading home.
Running & Fitness Desk race-day advice: Respect September. An 8:00 a.m. start does not guarantee cool conditions. Start the first mile under control and give yourself permission to run by effort instead of obsessing over pace if the morning is hot or humid.
Best for: First-time racers, social runners, families and anyone who wants to turn a 5K into a Hill Country day trip.
Mellow Trail Race 5K — Spicewood
Saturday, September 12, 2026
Road runners curious about trails have a very different option the same weekend.
The Mellow Trail Race takes place at Pace Bend Park in Spicewood and offers everything from a youth mile and 5K through a marathon. The 5K begins at 8:15 a.m. and is currently listed at $60 before processing fees, with a price increase scheduled after September 2. Packet pickup is available Friday evening and race morning.
The finish area sits near Lake Travis, which gives the event more of an outdoor-adventure feel than your typical neighborhood road race.
But trail 5K and road 5K are not interchangeable.
Your normal pavement pace may mean almost nothing once uneven footing, turns and elevation enter the conversation. Shorten your stride when necessary, watch where you’re stepping and run the terrain instead of fighting it.
Best for: Runners trying their first trail event, outdoorsy families and anyone more interested in the experience than a perfectly even mile split.
Noche Trail Runs 5K — Junction
Saturday, September 19, 2026
Now things get interesting.
Noche takes the normal Saturday-morning 5K formula and tosses it out the window.
The 5K starts at 8:00 p.m. at South Llano River State Park in Junction. The organizer describes the course as wide rocky and single-track trails and lists roughly 1,000 feet of elevation gain per longer course loop. Current 5K registration is $60, increasing to $65 after September 4 if the race has not sold out. State park entry is included in the registration price.
For the 5K runner, the appeal is simple: you get the atmosphere of a serious trail-running event without signing up for 13, 27 or 40 miles.
Night trail running does require extra preparation. Your footing matters more, visibility changes and pacing should be conservative until you understand the terrain.
This is not the race to buy a headlamp on the drive to Junction and discover at mile two that the batteries came installed sometime during the George W. Bush administration.
Test your lighting before race weekend.
Best for: Adventurous runners, trail runners and anyone looking for a 5K that feels completely different.
Oktoberfest Kraut Run 5K — Fredericksburg
Saturday, October 3, 2026
This might be the easiest race on the list to turn into a full Hill Country weekend.
The 17th Annual Oktoberfest Kraut Run starts at 8:30 a.m. in Fredericksburg and includes a timed 5K, timed 8K and non-timed 5K walk. The event benefits literacy and youth programs through Fredericksburg Morning Rotary.
Adult registration for the timed 5K is currently $40 through August 31 and rises to $45 beginning September 1. Organizers also note that the race uses an open-road course, meaning runners may encounter vehicles and should remain alert at intersections.
The obvious attraction is location.
Race in the morning, then spend the rest of the day in Fredericksburg. That makes this an especially good option for runners trying to convince a spouse or friend that traveling for a 3.1-mile race is completely rational.
Running & Fitness Desk race-day advice: Don’t let cooler October expectations fool you. Check the actual forecast before deciding what to wear. Hill Country mornings can swing considerably this time of year.
Best for: Couples, friend groups, recreational runners and anyone looking for a destination 5K.
Dia de los Muertos 5K Run/Walk — San Marcos
Saturday, October 31, 2026
Some races are memorable because of the course. Others become memorable because they actually feel connected to the community hosting them.
The 13th Annual Dia de los Muertos 5K Run/Walk & Kids Fun Run takes place at Hernandez Elementary in San Marcos with an 8:00 a.m. 5K start followed by a kids race.
Proceeds support the Johnnie T. Rosales Memorial Scholarship, which awards scholarships to graduating San Marcos High School seniors. The organizer encourages participants to wear Day of the Dead running gear, and the event includes music, awards and community remembrance activities. Adult registration is currently $35 through October 16 before increasing to $40.
This is also a run/walk event, making it an approachable target for newer runners or someone returning to fitness.
There is absolutely nothing wrong with using a planned run/walk strategy. In fact, deciding beforehand that you’ll run four minutes and walk one minute is usually smarter than sprinting the first half-mile and inventing a survival strategy later.
Best for: Walk/run participants, families, newer racers and runners who value community events.
New Braunfels Half Marathon 5K — New Braunfels
Sunday, November 15, 2026
By mid-November, runners targeting a faster 5K finally have a better chance of getting cooperative weather.
The New Braunfels Half Marathon, 10K and 5K starts and finishes at Stars and Stripes Drive-In Theatre. The 5K begins at 7:40 a.m., and organizers describe the certified courses as scenic country-road routes designed to be fast and relatively flat.
Current 5K registration is $40 through August 31, $45 from September 1 through November 14 and $50 on race day. Participants receive a tech shirt and finisher medal.
If you spent summer building fitness and want to see what that work did for your 5K time, this is the race on this list I’d circle.
Just don’t turn every training run between now and November into a time trial.
Easy days should still be easy. Add a modest amount of faster running once or twice per week, keep your overall training consistent and arrive at the starting line rested enough to actually use the fitness you built.
Best for: Recreational runners chasing a fall PR and first-timers wanting a traditional race setup.
Boerne Family YMCA Turkey Trot 5K — Boerne
Saturday, November 21, 2026
If you like a larger community race, Boerne deserves serious consideration.
The 15th Annual Boerne Family YMCA Turkey Trot starts at Main Plaza and follows paved, quieter neighborhood streets. The 5K starts at 8:10 a.m., following the 10K start, and organizers report that the 2025 event drew more than 1,400 participants.
Registration for the adult 5K is currently $35 through September 30 before increasing to $45 in October and $55 in November. Participants must register by October 31 to be guaranteed a shirt and participation medal.
A field that size gives newer runners something fun that smaller races sometimes cannot: race-day energy.
Just don’t let that energy make your decisions for you.
The first half-mile of a crowded 5K can feel absurdly easy because everyone around you is moving quickly. Let runners go. Settle into your effort. You can start passing people later.
Best for: Families, first-time racers, social runners and runners who enjoy a larger starting-line atmosphere.
Comanche Trace Turkey Trot 5K — Kerrville
Wednesday, November 25, 2026
For something smaller and more scenic before Thanksgiving, head farther west.
The Comanche Trace Turkey Trot 5K in Kerrville follows a route around the Creeks Golf Course at Comanche Trace. The race starts at 7:30 a.m. and benefits development of the Guadalupe River Center.
Organizers welcome runners and walkers along with strollers and well-behaved leashed dogs. Registration is limited to 200 participants, with current entry priced at $55 through October 1.
That 200-runner cap gives this race a very different personality from Boerne.
If giant starting corrals aren’t your thing, a smaller field can be refreshing. You still get timing, competition and race-day structure without feeling like you’re navigating a freeway interchange for the first mile.
And by late November in Kerrville, there’s at least a reasonable chance you’ll remember what running feels like when the air isn’t actively trying to cook you.
Best for: Smaller-race fans, walkers, families and runners looking for a scenic Thanksgiving-week event.
September 5K or November 5K? They’re Different Races
If you’re deciding when to race, weather should be part of the conversation.
For a September Hill Country 5K, train with the assumption that race morning could still be warm. Your effort matters more than an arbitrary goal pace. Hydration before the race matters. So does choosing clothing that handles heat well.
By November, cooler conditions may make faster running easier, but there is no guarantee. Texas can produce chilly mornings, warm afternoons and 30-degree temperature swings without appearing remotely embarrassed about it.
Check conditions during race week and adjust.
If you’re training for your first 5K, you do not need an elaborate plan. Three or four active days per week can take you a long way when they’re consistent: a couple of comfortable runs or run/walk sessions, one gradually longer easy workout and perhaps a small amount of strength work.
You are training to cover 3.1 miles confidently—not audition for the Olympic team.
Which Texas Hill Country 5K Should You Choose?
Pick the race that makes you want to train.
Choose Gruene if atmosphere and location matter most.
Choose Mellow or Noche if pavement is starting to bore you.
Choose Fredericksburg if you want a race that becomes a weekend trip.
Choose Dia de los Muertos if community and family participation matter more than your finishing time.
Choose the New Braunfels Half Marathon 5K if you’re interested in testing your speed.
Choose Boerne if you want the energy of a larger Thanksgiving-season event.
Choose Comanche Trace if you prefer a smaller, scenic field.
There isn’t one correct fall 5K.
The useful race is the one that gets onto your calendar and gives your training direction.
Running & Fitness Desk Take
Fall is probably the best time of year to be a recreational runner in the Texas Hill Country.
September gives you adventurous events while you’re still carrying summer fitness. October adds festival races and cooler mornings. November brings traditional road races, Turkey Trots and conditions that can finally reward all those sweaty miles you put in during July and August.
You also don’t need to wait until you think you’re “fast enough.”
If you can comfortably walk, run or combine the two for roughly three miles, there are races on this list that can work for you right now.
Pick one. Give yourself several weeks to prepare. Train consistently instead of trying to cram fitness into the final 10 days.
And when race morning arrives, don’t worry about what everybody else at the starting line is doing.
Run your race.
