Most people believe you have to choose. You're either a runner or a lifter. Either you're chasing a marathon PR or you're adding weight to your squat. The fitness world has spent decades reinforcing this either/or mentality — and it's holding a lot of people back from reaching their actual potential.
Katie Jones is proof that this is flat-out wrong. With 11 marathons, three powerlifting meets, a lifelong competitive swimming background, and — most recently — a completed 70.3 Ironman, she's built one of the most well-rounded athletic resumés you'll find outside of a professional training facility. And she did it while working a full-time job, traveling for work, and planning a wedding. On the latest C3 Method podcast, Rob Polenik — a certified strength and nutrition coach with a Master's in Human Nutrition, ACSM personal training certification, NASM Corrective Exercise Specialist credential, and over 3,000 clients coached — sat down with Katie to unpack exactly how she makes the hybrid athlete lifestyle work.
Whether you're a runner who knows you should be lifting, a lifter who wants to try an endurance event, or someone who's just tired of feeling like you have to pick a lane, this episode is for you. Here's what you'll learn: how to schedule training when life is genuinely busy, how to time your nutrition to support both endurance and strength performance, how to stop the all-or-nothing thinking that keeps most people stuck, and why getting uncomfortable is the only way forward.
What It Actually Means to Be a Hybrid Athlete
The term "hybrid athlete" has gotten more popular recently, but the concept is simple: you train for and compete in both strength-based and endurance-based sports — not one or the other. You're not a powerlifter who jogs occasionally. You're not a runner who does a few sets of curls after a long run. You're genuinely pursuing performance in both disciplines.
Katie's journey into hybrid training started naturally. She swam competitively from age five through college and ran cross-country simultaneously at Westminster College — overlapping seasons and all. That dual-sport foundation gave her an athletic base that most single-sport athletes never develop. When she connected with Rob around 2020, she was already running marathons and wanted to start powerlifting. The question wasn't if she could do both — it was how.
Why Swimmers and Runners Make Surprisingly Good Powerlifters
There's a common assumption that swimmers are uncoordinated outside the water and that runners are too lean to be strong. Neither holds up under scrutiny. The cardiovascular efficiency that endurance athletes build translates directly into recovery capacity between lifting sets and between training sessions. Katie competed in three official powerlifting meets while continuing to run marathons — and her body handled both because the programming accounted for both.
If you've been told your endurance training will kill your strength gains, or that heavy lifting will slow you down on race day, you're working from outdated information. The research on concurrent training has advanced significantly, and the real differentiator isn't the training style — it's how intelligently the program is built around your recovery capacity.
How to Schedule Training When You Have a Full Life
This is where most hybrid training conversations fall apart. People hear "train for an Ironman and powerlifting at the same time" and immediately think: I don't have time for that. Katie's answer to the scheduling question was direct and unglamorous: write it down.
Not in a vague, aspirational way. Actually put your workouts in your calendar like they're meetings you can't skip. Assign a day, assign a time block, and assign a realistic duration. Katie noted that during Ironman training, she consistently underestimated how long her bike sessions would take — she'd plan for one and a half hours and get off the bike three hours later. That's not a planning failure; that's data. You collect it, you adjust, and next week's calendar is more accurate.
Start Small, Then Build
If you're new to scheduling workouts consistently, start with two or three days per week. Get to the gym, do the workout, and actually time it. Then schedule it more precisely the following week. You won't have a perfect plan before you start — and waiting until you do is just a more socially acceptable form of procrastination.
Rob recommended the book Elastic Habits by Stephen Guise as a framework for this exact problem. The concept is simple: give yourself three levels for every habit — the ideal version, the "good enough" version, and the minimum viable version. On a day when traffic was bad and you only have 20 minutes, the minimum viable workout is still a win. It keeps your streak alive and keeps your body moving. That flexibility is what separates people who stay consistent for years from people who fall off every time life gets complicated.
Nutrition Timing: The Piece Most Hybrid Athletes Miss
Katie described herself as a notorious underfueler in her early 20s — eating very little during the week and then eating everything in sight on weekends. Sound familiar? This pattern is almost universal among athletes who train hard but haven't built intentional nutrition habits. And the performance cost is real: she noted that her fitness now, at 30, is measurably better than it was at 21 — and she attributes that directly to nutrition, not just training.
The specific fix that made the biggest difference wasn't counting calories more carefully. It was timing. Katie trains at 6 a.m. If she wasn't eating meaningfully until noon, she was asking her body to recover from a hard training session on essentially nothing for six hours. That's a problem whether your next session is that afternoon or the next morning. Under-fueling post-workout doesn't just slow recovery — it compromises the quality of your next training session before you've even shown up for it.
A Practical Approach to Tracking Without Obsessing
Katie uses MyFitnessPal, but not in a rigid, every-meal-every-day way. Her approach: track consistently for about two weeks when starting a new training phase or nutrition goal. Once she understands what her calorie and protein targets look like in real food, she stops tracking and just eats what she knows works. She revisits tracking when something feels off or when her training demands shift significantly.
This is a sustainable model. Obsessive tracking burns people out. No tracking at all leaves too much to guesswork. Periodic, intentional tracking gives you the data you need without making every meal feel like a math problem.
Strength Training Protects Your Body for the Long Run — Literally
Before working with Rob, Katie ran six days a week and dealt with a steady stream of minor injuries throughout her college years and early marathon training. She ran her first marathon in 2014 at age 18 and described that period as riddled with "weird little hiccup injuries." Since integrating consistent strength training into her program, she's remained healthy through 11 marathons, three powerlifting meets, and an Ironman.
This is not a coincidence. Strength is never a weakness — a phrase Rob used in the episode that applies directly here. When you build stronger glutes, hamstrings, and single-leg stability, your running economy improves and your injury risk drops. When your upper body and core strength increase, your swimming efficiency goes up. When your posterior chain is developed, your cycling power improves. Strength training isn't a detour from endurance performance — it's infrastructure for it.
If you've been skipping the gym because you're "just a runner" or "just a triathlete," you're not saving energy for your sport. You're accumulating structural vulnerabilities that will eventually catch up with you.
Building the Mindset That Makes Hybrid Training Sustainable
The most underrated part of Katie's story isn't her athletic resumé. It's that she built it through consistent, patient action — and she did it while fully acknowledging that it was hard. She talked about mentally checking out of her nutrition after the Chicago Marathon. She talked about weeks where planning felt overwhelming. She talked about learning that her 20-something self who "didn't like change" was actually someone who craved new challenges — she just hadn't tested that enough yet.
The mindset shift that makes hybrid training sustainable comes down to two things:
1. Stop waiting for the perfect plan. You don't need to know exactly how your Ironman training will look in month four before you sign up. Sign up, start planning, and refine as you learn. Rob pointed out that most people want a perfect plan before they've had a single experience — but experience is the only thing that tells you what to plan for.
2. Embrace temporary discomfort. Joining a new run club, hiring a coach, signing up for a race you don't feel ready for — all of these feel uncomfortable for a brief, finite period. The outcome on the other side is compounding. Katie put it simply: the first step is the hardest one. After that, you're already walking in the right direction.
Key Takeaways
- Schedule your workouts like appointments — assign a specific day, time, and duration, and put them in your calendar before the week starts.
- Track your nutrition intentionally for two-week windows to establish your baseline, then step back from obsessive logging once you know your numbers.
- Prioritize nutrition timing, not just totals — eating enough by the end of the day doesn't help if you're running on empty for the six hours after your morning workout.
- Add strength training to your endurance program — it reduces injury risk, improves efficiency in your sport, and extends your athletic career.
- Use the "elastic habit" framework — define your ideal workout, a good-enough version, and a minimum viable version so you never go to zero on a hard day.
- Sign up for the race, reach out to the coach, join the run club — discomfort is temporary, and taking the first step is always the hardest part.
- Revisit your plan regularly — your training demands, life circumstances, and recovery capacity all shift, and your approach needs to shift with them.

Frequently Asked Questions
Q: Can you really train for both powerlifting and marathon running at the same time?
Yes — and Katie Jones is a living example of it. The key is intelligent programming that accounts for recovery across both disciplines. You'll need to manage training volume carefully and pay close attention to nutrition timing and sleep, but concurrent strength and endurance training is not only possible, it's increasingly well-supported by sports science research.
Q: How do hybrid athletes structure their nutrition differently from single-sport athletes?
Hybrid athletes often have higher overall caloric needs due to the combined volume of strength and endurance training. The biggest difference is nutrient timing — making sure carbohydrates are available before and after training sessions, and that protein intake (aiming for roughly 0.7–1.0g per pound of bodyweight daily) is spread consistently throughout the day rather than backloaded. Underfueling during the training day is the most common mistake hybrid athletes make.
Q: Will running kill my strength gains or slow down muscle growth?
Not if your program is designed correctly. Concurrent training does require thoughtful sequencing — for example, avoiding heavy leg day immediately before a long run — but it does not inherently prevent strength development. Many hybrid athletes find that their endurance base actually improves their work capacity in the weight room over time.
Q: How do I find time to train for both endurance events and strength if I work full time?
Start by writing your workouts into your actual calendar with specific time blocks. Be realistic about duration — most people underestimate how long sessions take, especially endurance work. Identify your two or three most reliable training windows per week and protect them. As Katie noted, even having a backup plan for when work runs late (e.g., "if I work late Tuesday, I move the bike to Thursday") dramatically increases how often you actually follow through.
Q: Do I need a coach to become a hybrid athlete, or can I figure it out on my own?
You can make progress on your own, but a coach dramatically accelerates the process and helps you avoid costly mistakes — like overtraining, poor nutrition timing, or structuring your schedule in a way that sets up injury. The value of having an expert who can adjust your plan in real time based on how your body is responding is hard to overstate, especially when you're layering two demanding training modalities on top of a full life.
Q: What's the best first step for someone who wants to become a hybrid athlete?
Pick one new thing and sign up for it. If you're already a lifter, register for a 5K or a sprint triathlon. If you're already a runner, commit to three strength training sessions per week for 60 days. Then reach out to a coach who understands both sides of the equation and can help you build a plan that doesn't sacrifice one discipline for the other.
Conclusion
The hybrid athlete approach isn't about being mediocre at two things. It's about being genuinely capable and resilient across multiple demands — and building a body that can handle more than you thought possible. Katie Jones didn't stumble into her results. She planned, adjusted, stayed consistent through the uncomfortable phases, and kept showing up even when her nutrition wasn't perfect and her schedule was chaotic.
That's the real lesson from this episode. Hybrid athlete training works — not because it's a magical formula, but because it respects the whole athlete. Strength supports endurance. Endurance builds capacity. Nutrition timing ties both together. And planning — not perfection — is what holds it all in place. If you've been waiting for the right moment to start, this is it. Sign up for the race. Hire the coach. Show up uncomfortable. The discomfort won't last. The results will.
