How to Run and Train Safely in High Heat

in

High temperatures are unavoidable during Texas summers, but they do not have to stop your training. With a few smart adjustments, you can protect your heart and body while continuing to build toward your goals.

When temperatures and humidity rise, your body works harder to cool itself. This can increase cardiovascular strain and the risk of dehydration, heat exhaustion and exertional heat illness.

We spoke with Ryan Quinn, MD, a board-certified sports cardiologist at Ascension Texas Cardiovascular in Austin. Dr. Quinn specializes in preventive cardiology and works with active people and athletes to address their unique cardiovascular needs.

Here is how to stay safe, train smart and keep getting in your miles during the Texas heat.

Stop running, move to a cool place, and let someone know if you experience:

  • Dizziness or lightheadedness
  • Headache or nausea
  • Unusual weakness or fatigue
  • Muscle cramps
  • An unsteady walk
  • A weak or rapid pulse
  • A sudden decline in coordination or performance

These may be warning signs that your body is struggling to manage the heat.

Confusion, disorientation, collapse, seizure, unusual behavior or loss of consciousness may indicate exertional heat stroke. This is a medical emergency. Call 911 and begin rapid cooling with cold compresses, shade and fanning, when available, while emergency help is on the way.

Austin Marathon Half Marathon & 5KChoose the Right Time to Run

Whenever possible, schedule outdoor workouts for early in the morning or later in the evening. Avoid the middle of the day, when direct sunlight and temperatures are often at their highest.

Before heading out, check the temperature, humidity, heat risk and air quality. Even a familiar route may require a different plan when conditions become more demanding.

 

Give Your Body Time To Adapt

Heat acclimatization happens gradually. The American College of Sports Medicine recommends allowing approximately one to two weeks of repeated, progressive exposure for most heat-related adaptations to occur.

Begin with shorter, easier workouts. Gradually increase your duration and intensity as your body becomes more comfortable in the conditions.

Do not wait until the middle of your run to think about hydration. Drink fluids throughout the day and begin your workout well hydrated. Pre-hydration with or without electrolytes can go a long way.

Carry water, plan a route with water access or create shorter loops near your home or vehicle. Longer or more demanding sessions may also require electrolytes, particularly for runners who sweat heavily. If you are one of those people, drinking 16-32oz of water mixed with electrolytes prior to a run is very helpful.

Hydration supports circulation and sweating, which are both important for regulating body temperature.

Wear loose, lightweight and breathable clothing. Lighter colors can help reduce heat absorption, while a hat or visor may provide additional sun protection.

Apply sunscreen before heading outside and reapply it according to the product instructions. Choose shaded routes when possible and avoid exposed pavement during the hottest parts of the day.

Heat can make a small problem more serious, so avoid putting yourself in a situation where you are far from help.

Tell someone where you are going, run with a friend or choose a route that keeps you close to water, shade and transportation. Bring your phone and identification, especially during longer workouts.

Check in with your training partners and ask them to do the same for you.

Austin Marathon Half Marathon & 5KTake Extra Care When You Are Sick

Do not try to push through a hard workout when you have a fever, recent illness, reduced oral intake, or vomiting or diarrhea. These conditions can increase your risk of heat-related illness.

Certain medications (particularly diuretics, ACE inhibitors, and ARBs) and cardiovascular or chronic health conditions may also affect how your body responds to heat. Talk with your doctor before making major changes to your training, hydration or medication routine.

How to Avoid Burnout During Training

in

Training for the Austin Marathon is exciting, but let’s be real: somewhere between the long runs and early alarms, that excitement can start to fade. Burnout doesn’t always look like a dramatic collapse. Sometimes it’s the slow drain of motivation, the heaviness in your legs that rest doesn’t seem to fix, or the creeping thought of skipping just one more run.

The good news? Burnout is preventable. Here’s how to keep your fire burning all the way to the start line on race day.

Training burnout is a state of physical and mental exhaustion caused by prolonged, excessive training without adequate recovery. It goes beyond normal tiredness. When you’re burned out, rest alone doesn’t feel like enough, and the joy of running fades.

Common signs of training burnout include:

  • Persistent fatigue that doesn’t improve with sleep
  • Declining performance despite consistent effort
  • Irritability, mood swings, or loss of motivation
  • Increased injuries or lingering soreness
  • Dreading workouts you once looked forward to

Austin Marathon Half Marathon & 5KWhy Runners Training for the Austin Marathon Are Especially Prone

Austin’s training season spans the Texas summer and fall, meaning you’re building mileage during some of the hottest months of the year. Combine heat stress with a demanding training plan, and your body works harder than the miles alone suggest. That’s why smart recovery isn’t optional here. It’s essential.

1. Follow the 80/20 Rule

Run 80% of your weekly miles at an easy, conversational pace. Only 20% should be hard efforts like tempo runs, intervals, or race-pace work. Most runners go too hard too often, which accelerates fatigue without accelerating fitness.

2. Build in Recovery Weeks

Every 3 to 4 weeks, reduce your mileage by 20-30%. These step-back weeks let your body absorb the training and come back stronger. They’re not a sign of weakness. They’re how adaptation actually works.

3. Prioritize Sleep Like It’s a Workout

Sleep is when your muscles repair and your nervous system resets. Aim for 7-9 hours per night. If you’re consistently getting less, no training plan can outrun the fatigue debt you’re building.

4. Fuel Properly (Yes, That Means Eating Enough)

Underfueling is one of the fastest paths to burnout. Your body needs carbohydrates, protein, and healthy fats to support the miles. If you’re constantly hungry, exhausted, or getting sick often, take a hard look at your nutrition.

5. Mix Up Your Routine

Run a new route. Try a trail instead of pavement. Join a local Austin running group for your long run. Cross-train with cycling or swimming. Variety keeps your mind engaged and reduces repetitive stress on your body.

6. Set Process Goals, Not Just Outcome Goals

“Finish the Austin Marathon” is a great goal, but it’s months away. Set weekly process goals: hit three easy runs, complete one speed session, foam roll after every workout. Small wins keep motivation alive when the finish line feels far off.

7. Listen to Your Body (Really)

There’s a difference between “I’m tired” and “something is wrong.” Learn to tell the two apart. A planned rest day when you’re feeling off is always smarter than pushing through and losing a week to injury or illness.

If you’re reading this and thinking “too late,” here’s what to do:

  1. Take 3-5 full rest days. No running, no guilt.
  2. Reassess your training plan. Were you doing too much, too fast? Adjust.
  3. Talk to someone. A coach, a running partner, or even your Austin Marathon community. You’re not alone in this.
  4. Come back gradually. Start with easy, short runs and rebuild your joy before your mileage.

Frequently Asked Questions

How many rest days per week should marathon runners take?

Most marathon training plans include 1-2 full rest days per week. Listen to your body. If you need an extra rest day, take it. Consistency over months matters more than any single week.

Can mental burnout affect physical performance?

Absolutely. Mental fatigue directly impacts perceived effort, motivation, and even injury risk. Your brain and body aren’t separate systems. If your mind is fried, your running will suffer.

What’s the difference between overtraining and burnout?

Overtraining is a physical syndrome caused by excessive training load without recovery. Burnout includes the emotional and motivational components. They often go hand in hand, but burnout can set in even when your training volume looks “reasonable” on paper.

How do I stay motivated during a long training cycle?

Break it into phases. Celebrate milestones. Run with friends. Sign up for a shorter tune-up race. Remind yourself why you signed up for the Austin Marathon in the first place.

The Bottom Line

Burnout doesn’t have to be part of your Austin Marathon story. Train smart, recover intentionally, and remember that the goal isn’t just to get to the start line. It’s to get there healthy, strong, and genuinely excited to run 26.2 miles through the best city in Texas.

Your Austin Marathon journey should feel hard sometimes, but it should never stop feeling worth it.

Marathon vs Half Marathon Training Plans Compared

in

Deciding between the Austin Marathon and the Austin Half Marathon? You’re not alone. It’s one of the most common questions we hear from runners eyeing race day on February 14, 2027. Both distances are incredible achievements, but the training looks very different once you break it down.

Whether you’re a first-timer choosing your distance or a half marathoner thinking about going full, this guide compares the two training plans side by side so you can pick the path that fits your goals, schedule, and lifestyle.

Half Marathon (13.1 miles): Most plans range from 8 to 14 weeks, depending on your starting fitness. If you can comfortably run a 5K or 10K, 10 to 12 weeks is the sweet spot.

Full Marathon (26.2 miles): Expect 16 to 20 weeks of dedicated training. Most coaches recommend 16 weeks as the minimum for runners who already have a solid base of 15 to 25 miles per week.

For the 2027 Austin Marathon on February 14, that means starting your marathon plan no later than mid-October 2026 and your half marathon plan by early November.

Weekly Mileage Comparison

Half Marathon Full Marathon
Starting weekly mileage 12–20 miles 20–30 miles
Peak weekly mileage 25–35 miles 40–55 miles
Longest training run 10–13 miles 18–22 miles
Training duration 8–14 weeks 16–20 weeks
Days per week 3–5 4–6

The jump from half to full isn’t just double the distance. The physiological challenge increases roughly 3 to 3.5 times because of glycogen depletion, cumulative fatigue, and the pounding your muscles take beyond 90 minutes of running.

In half marathon training, your long run peaks around 10 to 13 miles. It’s challenging, but your body can largely fuel itself through stored glycogen.

In marathon training, long runs stretch to 18 to 22 miles. This is where things fundamentally change: you’ll need to practice fueling during your runs, your recovery demands increase significantly, and you’ll spend more time on your feet than your joints have ever experienced.

Pro tip: If you’re training for the Austin Marathon, use your long runs to practice with the same gels and hydration you’ll use on race day. The aid stations on course are your best friend, but your stomach needs to be trained too.

Half Marathon: Most runners can get through 13.1 miles with a good pre-race meal and maybe one gel around mile 8 to 10. Hydration matters, but “bonking” is rare.

Full Marathon: Nutrition becomes a make-or-break factor. “The Wall” at miles 18 to 22 is caused by glycogen depletion, and it’s preventable with proper fueling. You’ll need to practice taking in 30 to 60 grams of carbs per hour during long runs. This is non-negotiable for marathon success.

Both plans include quality workouts, but the emphasis shifts:

Half Marathon training leans heavier on tempo runs and threshold work because the race is essentially run near your lactate threshold. Speed sessions are shorter and more intense.

Marathon training prioritizes sustained marathon-pace efforts and progression long runs. The goal is teaching your body to hold a moderate effort for 3 to 5+ hours, not going fast for 90 minutes.

More miles means more recovery. Marathon training requires more rest days (or very easy days), more sleep, and greater attention to strength work. The injury risk goes up significantly past 40 miles per week, which is why most marathon plans build in a cutback week every 3 to 4 weeks.

Half marathon training is more forgiving. You can bounce back from a hard week faster, and the overall training load is more manageable around work, family, and life in Austin.

Choose the Austin Half Marathon if:

  • You’re new to distance running or stepping up from 5K/10K
  • You can commit 4 to 6 hours per week to training
  • You want a challenging but manageable goal
  • You’d rather run Austin’s incredible course without the 20-week commitment

Choose the Austin Marathon if:

  • You’ve completed at least one half marathon
  • You can commit 7 to 12+ hours per week to training
  • You want to push your limits and experience the full 26.2 through Austin’s neighborhoods
  • You’re ready to make fueling and recovery a priority

Frequently Asked Questions

Can I train for a marathon and a half marathon at the same time?

Most marathon training plans include a half marathon as a tune-up race 4 to 6 weeks before the full. So yes, you can race both, but train for the marathon as your primary goal.

How do I know if I’m ready to move from half to full marathon?

If you’ve run a half marathon comfortably, are currently running 20+ miles per week, and can commit to 16+ weeks of training, you’re ready to make the jump.

What pace should I run the Austin Marathon vs the Half Marathon?

Your marathon pace will typically be 30 to 90 seconds per mile slower than your half marathon pace. The extra distance demands energy conservation from mile one.

When should I start training for the 2027 Austin Marathon?

For a February 14, 2027 race day, begin your 16-week marathon plan around October 20, 2026. For the half marathon, starting in mid-November gives you plenty of time.
