The Summer Baseline: What Every High School Runner Should Test Before Training Ramps Up
Most high school runners do the same thing in late May: school ends, the schedule clears, and they lace up and start logging miles. Summer is when the real training happens … longer long runs, harder workouts, the base that will carry them through cross country season.
And most of them skip the single most important step before any of that begins.
Baseline testing.
I've coached runners at the high school and collegiate level, and the athletes who make the biggest jumps from spring to fall aren't always the ones who trained the hardest over the summer. They're the ones who trained the smartest … and that starts with knowing exactly where you stand before you take the first step.
Here's the full picture of what I put my athletes through at the start of every summer, why each piece matters, and what to do with the information.
Why Summer Is the Right Time for Baseline Testing
The transition out of the spring track season is the best window you'll get all year for honest assessment. Your body has just completed a full competition cycle. The urgency of race season is gone. You have 10–12 weeks before cross country begins.
That window is too valuable to waste guessing.
Baseline testing in early June gives you three things: a clear picture of your current physical and physiological state, enough lead time to address anything that needs attention, and a benchmark to measure your summer progress against. You can't improve what you haven't measured, and you can't protect what you don't know is at risk.
1. Pre-Injury Screening: Find the Problem Before the Problem Finds You
The number one cause of missed cross country seasons isn't overtraining — it's running into fall with an unresolved issue from spring. Shin pain that was "manageable" in April becomes a stress fracture in August.
A pre-injury movement screen takes about 30–45 minutes and is worth every minute. What you're looking for:
Hip and glute function. Weak glutes are implicated in nearly every common running injury… IT band syndrome, patellofemoral pain, tibial stress reactions. A simple single-leg squat assessment reveals a lot. If the knee collapses inward on one side, that's a red flag.
Ankle mobility. Restricted dorsiflexion (the ability to flex your foot toward your shin) is one of the most underdiagnosed contributors to lower leg injury in high school runners. Limited ankle mobility forces compensation up the chain… through the knee, hip, and lower back.
Asymmetry. Left-right differences in range of motion, strength, or movement patterns often predict where an injury will occur. Screenings should always be bilateral. A small asymmetry isn't necessarily a problem; a large one is a conversation to have before summer mileage climbs.
Previous injury sites. Any area that was sore, tight, or symptomatic during the spring season deserves specific attention. "It calmed down by the end of the season" is not the same as "it's resolved."
If anything comes up in screening, a session with a sports physical therapist before summer training begins is a much better investment than six weeks in a boot in September.
2. Iron Testing: The Silent Performance Thief
Iron deficiency and its more advanced form, iron-deficiency anemia is one of the most common and most missed reasons high school runners plateau or decline in the summer. It's also more prevalent than most coaches and parents realize, particularly in female athletes and in any runner who has significantly increased their mileage.
Iron is required to produce hemoglobin, which carries oxygen to your working muscles. When iron is low, your aerobic capacity drops. Runs that should feel easy feel hard. Times stagnate or get slower despite consistent training. Athletes often describe feeling "flat" or "heavy" and coaches sometimes misread it as a motivation or effort problem when it's a blood problem.
What to test: A basic blood panel from your physician should include ferritin (stored iron), serum iron, hemoglobin, and hematocrit. Ferritin is the most sensitive marker a runner can have normal hemoglobin but low ferritin and still be performing below their potential. For runners, a ferritin level below 40 ng/mL is worth addressing even if it falls in the "normal" lab range.
When to test: Early June, before heavy summer training begins. If a deficiency is found, it typically takes 8–12 weeks of supplementation and dietary changes to restore levels meaningfully. Starting in June gives you time before cross country season.
Who's most at risk: Female runners (due to menstrual losses), athletes who have recently increased mileage significantly, vegetarians and athletes who eat little red meat, and any runner who had a notably difficult spring season.
Talk to your family doctor or a sports medicine physician about ordering a panel. It's a simple blood draw with potentially significant performance implications.
3. Biomechanics: What Your Running Form Is Costing You
Form problems don't just create injury risk they also waste energy. An athlete who overstrides, collapses at the hip, or runs with excessive vertical oscillation “aka bouncing” is working harder than they need to for every single step. Over a summer of training, inefficient mechanics compound into slower times and higher injury rates.
A video gait analysis done at the start of summer is one of the most high-value investments a high school runner can make. What it should assess:
Foot strike and ground contact. Where the foot lands relative to the center of mass matters. A heel strike far out in front of the body is a braking force on every step. This doesn't mean everyone needs to be a midfoot striker but ground contact should be happening below or near the hips, not far ahead of them.
Hip drop and pelvic stability. This ties back to glute strength from the screening section. Excessive hip drop during the stance phase is one of the most reliable predictors of iliotibial band issues, hip flexor strain, and patellofemoral pain.
Arm carriage and upper body tension. Crossed arms, clenched fists, and forward head position all affect running economy. These are often easy fixes with cues and drills.
A gait analysis doesn't need to happen in a lab. Slow-motion video from a phone, taken from the rear and side, gives a trained eye plenty to work with. The key is reviewing it with someone who knows what they're looking at and can translate observations into a specific drills and cues protocol for the summer.
4. Lactate Testing: Building Your Summer Training Zones the Right Way
If you're training without knowing your actual physiological thresholds, you're guessing. And most high school runners and many of their coaches are training too hard on easy days and not hard enough on hard days. The result is a narrow band of moderate-intensity training that builds neither aerobic base nor race-specific fitness as efficiently as structured training would.
Lactate threshold testing gives you data that makes every run more purposeful.
What it measures: The exercise intensity at which lactate begins to accumulate in the blood faster than it can be cleared. This threshold often called LT1 (aerobic threshold) and LT2 (anaerobic threshold or "tempo pace") corresponds to specific heart rate and pace ranges that should anchor your training zones.
How it works: The protocol involves running at progressively increasing speeds on a track or treadmill, with small blood samples taken (typically from the fingertip or earlobe) at each stage to measure blood lactate concentration. The test takes about an hour and is conducted by a sports performance professional.
Why it matters for high school runners: If your easy runs are too fast, you're accumulating fatigue that compromises your quality sessions and undermines your aerobic development. If your tempo runs are too slow, you're not creating the training stimulus that lifts your threshold. Zone-based training built on actual threshold data fixes both problems.
For athletes who don't have access to formal lactate testing, a well-executed field test such as a 30-minute time trial combined with heart rate data can give a reasonable approximation of threshold pace to structure summer training. But if access to proper testing is available, it's worth doing once. The data is good for the season and gives a concrete before/after comparison when retested in August.
5. Nutrition Audit: Fueling Summer Training the Right Way
Summer training is higher volume than most high school runners have experienced during the school year. Fueling that load and recovering from it requires intentional attention to nutrition that goes beyond "eat well."
Caloric intake. This is the most commonly missed piece. Athletes in heavy training who are under-fueling don't just perform poorly they're at elevated risk for stress fractures, hormonal disruption, illness, and overtraining syndrome. If an athlete is losing weight or feeling chronically flat during summer base-building, the first question to ask is whether they're eating enough, not whether they're training too hard.
Carbohydrates are not the enemy. Distance runners need carbohydrates for glycogen replenishment and quality training output. Low-carb approaches that work for sedentary adults are counterproductive for high school runners in summer training. Rice, oats, pasta, potatoes, fruit these are not indulgences for an athlete in training, they're fuel.
Protein timing. Muscle repair and adaptation happen primarily in the 30–60 minutes after a hard effort. Getting 20–25g of quality protein (eggs, Greek yogurt, chocolate milk, chicken) in that window meaningfully improves recovery. Many high school athletes skip post-run nutrition entirely or wait too long.
Hydration. Summer heat changes everything. A runner who is 2% dehydrated by body weight runs measurably slower and perceives effort as significantly harder. Sweat rates vary widely and some athletes lose 1–2 liters per hour in summer heat. Establishing a consistent hydration habit (not just drinking when thirsty) is a summer-specific skill worth building early.
6. Mental Health Check-In: The Piece Most Teams Skip
High school athletes are under more psychological pressure than any generation before them. Academic demands, social media, college recruiting anxiety, performance expectations and training on top of all of it. The summer transition is one of the most important windows to address mental readiness, not just physical readiness.
This doesn't have to be complicated or clinical. It starts with a direct, low-stakes conversation. As a coach, I build a simple check-in into the start of every summer:
How are you feeling about running right now? Are you excited, burned out, anxious, neutral?
Was there anything from last season you're still carrying? Anything from a race, an injury, a moment that stuck with you?
What does a good summer look like to you? What would make you proud of this fall?
These questions accomplish a few things. They give you insight into where an athlete's head is before training begins. They normalize conversations about mental state as part of athletic preparation. And they often surface things — perfectionism, fear of injury recurrence, social pressure, relationship with times and ranking which will otherwise show up later as behavioral or performance problems.
For athletes who experienced burnout, a difficult season, or significant anxiety around competition in the spring, a more intentional off-ramp before summer training begins is worth building in. Not every athlete needs to see a sports psychologist, but every athlete benefits from knowing their coach sees them as a whole person, not just a set of times.
7. Strength Training Protocol: Building the Engine Before You Run the Race
High school distance runners are chronically under-muscled for what they're asking their bodies to do. Running 50+ miles per week on a foundation of minimal strength work is a recipe for overuse injury. Summer is the time to build the structural durability that protects all those training miles.
The goal of summer strength work is not general fitness, it's running resilience. That means focusing on movements that directly transfer to the demands of distance running.
Non-negotiable movements for high school runners:
Single-leg Romanian deadlift. Builds posterior chain strength (hamstrings, glutes) and challenges hip stability simultaneously. This is one of the most sport-specific strength exercises a distance runner can do.
Bulgarian split squat. Develops unilateral leg strength and exposes left-right asymmetry. Begin with bodyweight, progress to load only when movement quality is solid.
Copenhagen adductor holds. Groin and adductor strength is almost always undertrained in runners and is a primary factor in hip and pelvic stability.
Calf raises: heavy, slow, and with full range of motion. Achilles tendinopathy and calf injuries are epidemic in distance runners. Heavy, slow calf raises (also called soleus raises when done with a bent knee) are one of the best-evidenced preventive interventions available.
Deadbug and paloff press variations. Core stability, not core strength in the sit-up sense, but the ability to maintain a stable spine under load and during dynamic movement which underpins efficient running mechanics.
Summer programming structure: Two days of strength per week is the right starting point, rising to three days in June and July before tapering back to one or two as cross country season approaches and running volume increases. Strength sessions should not leave athletes too fatigued to run well the following day and that's a loading management issue, not a reason to avoid lifting.
The first two weeks of any new strength program should prioritize form over load. Teaching a high school athlete to hinge at the hip properly, brace their core, and control single-leg stability before adding weight is not slow, it's the fastest path to adaptation without injury.
Putting It All Together: A Summer Testing Checklist
Here's the short version you can take action on right now:
Movement screening (hip, ankle, asymmetry, previous injury sites)
Blood panel (ferritin, hemoglobin, hematocrit, serum iron)
Gait analysis (video, rear and side view, cadence count)
Lactate threshold test or field test equivalent
Coach check-in conversation (mental readiness, last season, summer goals)
Establish strength training baseline (movement quality assessment before loading)
Not every athlete will have access to every test on this list. Start with what you can access. Iron testing and a pre-injury screening can be done through a family physician and a physical therapist respectively, no specialized sports facility required. Gait analysis can be done with a phone. The mental health check-in costs nothing.
The athletes who arrive at cross country camp in August having done this work don't just feel more prepared, they are more prepared. They know their body's strengths and vulnerabilities. They've addressed the issues that were waiting to become injuries. They have training zones built on real data. And they've had a conversation about what this season actually means to them.
That's not a small advantage. That's the summer.
