It’s simple to admire IndyCar from the skin: The velocity throughout each road programs and ovals, and the lightning-quick reflexes of the drivers. What most don’t see is the work taking place contained in the cockpit, which is a battle towards warmth, gravity, and the restricted of bodily endurance over the course of two grueling hours.
There’s no energy steering, airflow, or break in depth. In loads of methods, it’s not simply racing—it’s survival. For Kyle Kirkwood, one of many sport’s rising stars, preparation for that form of struggling doesn’t start on the monitor. It begins within the health club, the kitchen, and even weeks upfront of the following race.
Jeff Richter is aware of this terrain properly. Because the energy and conditioning coach for 2024 Indy 500 champion Josef Newgarden, he’s seen firsthand how the acute calls for of IndyCar tailor the coaching for the drivers to be hybrid athletes—ones who can carry, dash, endure, whereas remaining mentally sharp in searing warmth for hours. His health club, positioned in Indianapolis, operates with out air con by design. When the temps climb into the 90s and the humidity units in, that’s when the actual work begins. “Sweat fairness,” Richter says, is greater than a mindset—it’s a prerequisite to acting at a excessive stage.
Each Kirkwood and Richter method the game from completely different roles, they share the identical mission: to construct and preserve elite bodily output when cockpit temperatures soar above 120 levels and each tenth of a second issues. Whether or not it’s race simulation in a heated room, constructing cognitive resilience underneath stress, or managing restoration between back-to-back IndyCar race weekends, they’ve developed methods to push the bounds whereas recovering from them instantly and well.
Whether or not you’re an athlete chasing the following milestone or just trying to practice smarter this summer season, there’s a lot to study from the paddock. M&F caught up with each Kirkwood and Richter to find out how they practice to beat the warmth whereas staying sharp when each second issues.

Acclimating to the Warmth
When cockpit temps hit 120 levels and the race stretches previous the two-hour mark, IndyCar drivers don’t get a water break, not to mention a timeout. That actuality shapes how Richter approaches coaching with Newgarden. His health club doesn’t simply tolerate warmth—it utlizes it. Situated within the coronary heart of Indy, the house is saved intentionally uncooled for coaching. “We truly do imagine in each the physiological and psychological diversifications that may happen from present process a coaching surroundings that has a excessive diploma of warmth,” Richter says. “They’re making a physiological adaptation that they’re going to have the ability to cool their our bodies higher as a result of they’ve educated on this.”
Drivers do complain at first, however ultimately, they grow to be accustomed to the sweat. Similar to the circumstances they face throughout a scorching race, there’s nothing they will do to vary the circumstances. “You do have the psychological facet as properly,” says Richter. The 2 are interconnected. If you happen to physiologically are acclimated to the warmth, you’re gonna have a greater psychological outlook they usually study to struggle.”
Kirkwood agrees with this sentiment. Whereas he’s not coaching with Richter, the Florida-based Andretti driver builds warmth publicity instantly into his weekly prep—particularly through the summer season stretch of the IndyCar calendar. “I’ll do a few hours every week in a warmth room round 120 levels, often staying in that Zone 3 or 4 vary,” he says. “Being outdoors in 95- to 100-degree temperatures with the humidity, that’s nearly a lot sufficient to simply practice outdoor for a few days every week.” For each Richter and Kirkwood, these coaching classes are managed discomfort with the aim of constructing the warmth a setting they carry out in quite than a deterrent when it comes time to race.
Each coach and athlete agree that you could’t half step that stage of conditioning, particularly whenever you add in the truth that drivers additionally must put on fire-resistant racing fits product of Nomex which might be designed with a number of layers of fire-retardant materials. “If you happen to’re simply coaching in 60-degree temps day by day of the week, it’s not going to be ample sufficient,” says Kirkwood. Whether or not it’s the weightroom or on a street course, coaching the place you sweat can actually assist your physique adapt, increase your psychological conditioning to make race day really feel much less like a shock and extra like second nature.
Each athlete and coach agree on this: You may’t faux this sort of conditioning. There’s no complement, sauna session, or chilly plunge that may absolutely put together you to carry out in excessive environments with out constant publicity. “If you happen to practice in 60 levels day by day, you’ll soften when it’s 90,” says Kirkwood. “It’s that easy.” Whether or not it’s within the weightroom or on a street course, coaching the place you sweat—actually—helps your physique adapt, raises your psychological ceiling, and makes race-day really feel much less like a shock and extra like second nature.
The Significance of Hydration
For IndyCar drivers, the price of under-fueling is greater than only a dangerous exercise. It may possibly additionally value them an opportunity at a podium end or worse. That’s why hydration is greater than only a behavior—it’s a technique. Richter approaches it like a math equation. Drivers can lose as much as eight kilos of physique weight in sweat throughout a race, making fluid loss much less theoretical and extra measurable. “In the event that they drink each drop of their in-car hydration system, that’s about 3.3 kilos of fluid. But when they’re dropping eight, there’s a niche,” Richter says. “And as soon as they lose greater than two p.c of physique weight, we all know efficiency drops. That’s when psychological errors creep in.”
Richter’s method to bridging this hole is information pushed. There are pre and post-session weigh-ins, electrolyte stability, and pre-race fluid loading. Alcohol is one thing most, if not all, drivers flag through the season due to its diuretic results. Even a couple of informal drinks to have fun a victory can create a hydration deficit that lingers into getting ready for the following race. “These are grown males that must make grown selections to have the ability to be on the high of the extent,” he says.
Kirkwood takes a equally disciplined method that’s constructed round consistency and personalization. Hydration usually begins a full week earlier than race day, with a mixture of water, electrolytes, and sweat testing. “Everybody’s completely different,” he says. “I take advantage of a electrolyte combine known as The Proper Stuff to preload early within the week, then I’ll swap to Liquid IV or DripDrop two hours earlier than the race for added glucose.” Kirkwood is aware of that when the race begins, it’s too late to repair a hydration difficulty.
Rehydration doesn’t cease when the checkered flag waves. Kirkwood doubles down post-race with tart cherry packets, protein shakes, and electrolyte blends—not simply to bounce again, however to remain forward of the following grueling stint. “Even whenever you really feel such as you’re rehydrated, your physique continues to be catching up,” he says. “Consuming can be vital. Simply as lots of the proper energy as you’ll be able to consumption post-event is essential.” For drivers and health club goers alike, the much less is identical: hydration isn’t simply concerning the bottle in your hand, it’s about realizing your wants, and constructing your restoration simply as you do your weekly exercises.
The way to Keep Sharp When It Will get Scorching
The bodily toll of IndyCar racing is simply half the equation. With speeds reaching previous 230 mph, a lapse in focus isn’t simply pricey— it may be catastrophic. That’s why Richter doesn’t simply practice the physique, he checks the mind underneath stress. Newgarden has to have the ability to do extra than simply hit an influence quantity on a machine, he has to have the ability to react at a second’s discover when his coronary heart price is elevated and his core temperature is spiking. Richter builds in cognitive drills—response lights, color-coded catches, and decision-making video games—after brutal intervals on the rower or assault bike. This helps simulate the identical high-stress, overheated chaos of a race.
Kirkwood backs this method. From expertise, he is aware of the actual cognitive breakdowns come after the bodily fatigue units in. “You’re in a hearth swimsuit, pulling 4 G’s into corners, and also you’re attempting to remain mentally excellent,” he says. To copy that stress, Kirkwood additionally incorporates mentally taxing drills into his warmth coaching, equivalent to response video games, hand-eye coordination drills, and screen-based cognitive duties when his coronary heart price is in zone 4 and 5. “You’re bodily and mentally exhausted, and attempting to remain sharp is essential. So doing a mixture of these issues when you’re bodily exerted is essential for a sport like this.”
The pairing of bodily pressure and psychological sharpness creates a hybrid method that on a regular basis athletes can adapt, too. Whether or not it’s operating circuits within the warmth and testing reflexes mid-rep, or monitoring how your focus shifts as fatigue builds, psychological toughness isn’t inbuilt consolation. It’s cast when your physique is working extra time. If you wish to personal your warmth coaching, it’s good to be simply as exact between the ears as you’re underneath the bar.

Restoration Begins Earlier than the Exercise Ends
Ready till the exercise is over to consider restoration often places you behind. For the IndyCar athletes Richter trains, restoration begins earlier than the primary set even begins. “Coaching is simply the stimulus,” he says. “The coaching is the deposit that you just put into your physique’s account. You’re not going to understand the ROI till you handle your self by consuming a great meal afterwards, by rehydrating your self, and sleep. That’s when the progress occurs.” He helps lay a basis of the restoration protocol must be simply as dialed-in because the coaching plan.
That is additionally every week to week actuality for Kirkwood. After the checkered flag, he’s dialed in on recalibrating his physique. That begins with structured consuming, relaxation, and sticking to his routine that helps him bounce again for the following occasion. “You just about beat your self all the way down to nothing,” he says. “Then you definately’re proper again into one other occasion the next weekend.” For IndyCar athletes, the stress of a race weekend taxes each system of their physique in a method that the common on a regular basis individual won’t ever expertise. A driver’s restoration plan has to match the flight or struggle state stress that’s positioned on every race day. “They bought to have the ability to get better as a result of in coaching, if we’re simply going specializing in sustaining what we have now,” Richter says. “Sadly, after they get within the race automotive, they’re compromised earlier than it begins.”
For the remainder of us, the lesson is straightforward: the restoration has to match your effort. Don’t simply chase depth—help it. Whether or not you’re pushing by an out of doors HIIT exercise in 95-degree warmth or grinding reps within the health club, what you do instantly after the session will both assist construct momentum or burn you out. Within the warmth, restoration isn’t choices—it’s crucial.
