If you are aiming for a fall marathon or half marathon, whether that is a race in Austin, Houston, or further afield, May is when a lot of runners in this city start building their base mileage. The timing means the heaviest weeks of training often land right in the middle of Austin’s hottest, most humid stretch of the year, which changes both the injury risk profile and the smart approach to building volume.
Here is what tends to go wrong for runners training through Texas summers, and how to structure your training to reduce the risk.
Why Summer Training Is Different From Cooler-Weather Training
Heat and humidity add a layer of physiological stress on top of the normal mechanical demands of distance running. Your body works harder to regulate temperature, heart rate tends to run higher at the same pace, and dehydration sets in faster, all of which can mask early warning signs of an overuse injury because everything already feels harder than usual. Runners training through the summer also tend to accumulate fatigue faster, which is exactly when form starts to break down and small mechanical issues get magnified.
The Injuries We See Most Often
IT Band Syndrome
Pain on the outside of the knee that worsens with continued running is one of the most common marathon training injuries, often tied to hip weakness or misalignment that changes how the iliotibial band tracks over the knee joint. Fatigue from heat can make this worse, since form tends to degrade faster on hot, humid runs.
Plantar Fasciitis
Heel and arch pain, especially sharp pain with the first steps in the morning, frequently develops from cumulative strain combined with training on hard surfaces or in worn-out shoes.
Runner’s Knee
Pain around or behind the kneecap, often linked to how the hip and pelvis are aligned and how that affects tracking of the kneecap during the running motion.
Lower Back and Hip Tightness
Many runners do not think of the low back as a running injury site, but a subtly rotated pelvis or restricted hip joint changes stride length and symmetry, which can produce both back discomfort and downstream knee or ankle issues, and dehydration from summer heat can add to overall muscle tightness.
Training Smart Through the Heat
Follow the 10 percent rule. Avoid increasing your total weekly mileage by more than about 10 percent from one week to the next. Most training-related injuries trace back to a spike in volume the body was not ready for, and that margin for error shrinks further when heat is already adding stress.
Move your key runs earlier. Shifting longer or harder training runs to early morning, before the heat and humidity peak, reduces the additional strain heat places on your cardiovascular system and can help preserve better running form deep into a long run.
Build in a down week every three to four weeks. A deliberate lower-mileage week allows tissue to recover and adapt before the next mileage increase, which matters even more when summer heat is already taxing recovery.
Do not skip strength work. Hip and core strength directly influence running mechanics. Runners who neglect strength training tend to develop compensatory movement patterns faster as fatigue sets in during longer runs, and heat-related fatigue accelerates that timeline.
Hydrate proactively, not reactively. Waiting until you feel thirsty means you are already behind. Consistent hydration before, during, and after summer runs matters for both performance and injury prevention.
What to Do When Something Starts to Nag
The single biggest mistake we see in summer marathon training is runners pushing through a nagging ache, assuming it is just heat fatigue, until it becomes a full injury that forces them to stop training weeks before their fall race. A mild ache that shows up at the same point in every run, or gets worse as mileage increases, is your body telling you something mechanical needs attention, separate from ordinary heat-related tiredness.
Our sports injury treatment approach for runners focuses on identifying the underlying mechanical cause behind sports injuries, whether that is a hip imbalance, restricted joint mobility, or asymmetric pelvic alignment, rather than just treating the site of pain. Addressing the actual cause early in a summer training block is usually the difference between a runner who adjusts their training and keeps going, and one who has to stop entirely a few weeks before race day in the fall.
A Mid-Training Tune-Up Is Worth Considering
Even without an active injury, many of our marathon training patients come in periodically through their training block simply to have their gait and alignment checked. Catching a small imbalance before it becomes a symptomatic injury is far easier than treating a full-blown overuse injury under race-day time pressure once fall arrives.
