I train the way I coach.Every single day.

Healthy body. Healthy mind. Built to last.

We all perform life every single day — and to perform at your best, you have to be mentally and physically in tune. That’s what I train and what I coach. I’m Peter: ex-professional footballer, hybrid athlete and coach to 100+ athletes. I run ultras, lift alongside them and plan recovery like a session — no hacks, just a plan you can follow.

Meet Your Coach

The athlete behind the programs.

I’m Peter Schaale — ex-professional footballer, hybrid athlete and founder of Relentless Theory. I won’t hand you a plan I wouldn’t run myself.

Who I am

A former professional footballer turned performance coach. Licensed Fitness Coach, Nutritionist, Personal Trainer & Performance Coach. I’ve coached 100+ athletes — youth, university and pro level, in person and online.

What I do every day

I live the hybrid life: I run long, including ultramarathons, and lift alongside it. The other 22 hours get the same care — food, sleep, routines and recovery are planned, not left to chance. I ran 60km on my 30th birthday to raise money for men’s wellbeing, and the next ultra is already on the calendar.

How I help you

Structured programs you can start today — running, strength or hybrid — with clear sessions, progressive weeks and injury prevention built in. Want me in your corner? 1:1 coaching wraps nutrition, sleep, habits and mental resilience around your training.

Why my philosophy works

Healthy body, healthy mind — they work as one, and you perform at your best when you’re in tune with both. Results come from showing up, not from shortcuts: a plan you can actually follow, progress that compounds week after week, and a mindset that holds when motivation doesn’t. Same approach for a pro roster and a first-time 5K runner.

Relentless isn’t intensity. It’s consistency.

PATH 03

Hybrid Path

Three levels of race readiness — Challenge, Perform, Win

Hybrid strength-and-endurance racing prep, built as a competitive ladder rather than a single plan — you train to survive it first, then to perform, then to actually win your heat.

Built to Challenge

Beginner-friendly — lays the foundation for long-term progress by reshaping strength and cardiovascular health from the ground up. Builds consistency, control, and capacity so you're ready to progress into Level 2 and 3 as your fitness evolves.

2x full-body compound lift sessions/wk
3x cardio sessions across different heart rate zones
Daily mobility for movement and recovery
Education on training zones, movement quality, and form

Built to Perform

Intermediate — builds on Level 1 with more volume and intensity, pushing body and performance forward while staying smart and consistent. Sets the stage to advance into Level 3, where performance and intensity meet precision.

2x full-body compound lift sessions/wk
3x cardio sessions targeting multiple heart rate zones
1x weekly full-body EMOM for work capacity & coordination
Daily mobility to support recovery and joint health

Built to Win

Advanced — where performance meets precision. Adds intensity, explosiveness, and complexity for those who've built the base and are ready to push limits, dialing in performance, conditioning, and resilience at a high level.

2x heavy compound lift sessions to maintain and push strength
3x cardio sessions including high-intensity work
1x explosive sprint & plyometric session for speed and power
Optional HYROX-style sim workout (cardio + resistance)

Real People. Real Results.

What They're Saying.

Athletes

★★★★★

Back-to-back games used to wreck me. Now my legs feel fresh into the second half of the season, and my recovery days actually mean something.

Rory

19 · University Basketball

★★★★★

Peter built a plan around my season, not against it. My vertical and my court speed both improved without adding extra gym days I didn't have time for.

Rita

21 · University Basketball

★★★★★

I used to fade by the third period. Now my legs hold up for every shift, and my own coach has noticed the difference.

Zoe

15 · Academy Ice Hockey

★★★★★

Getting ready for trials felt impossible to plan on my own. RT Athletics gave me a real structure for training, eating, and recovering that actually fit around my week.

Jamie

22 · University Soccer

★★★★★

RT Athletics helped me improve my performance at a top university level. My conditioning, my recovery between games, all of it stepped up once I had a real structure behind it.

Amadou

20 · University Soccer

★★★★★

I came in without a specific sport in mind, just wanting to get faster and stronger for tryouts. RT Athletics gave me a level of structure I never had training on my own.

Leon

20 · University Athlete

Everyday Athletes

★★★★★

I hadn't lifted consistently in years. Full Body got me back in the gym without overwhelming me — three months in and I'm stronger than I was at 25.

Felix

34 · Software Engineer · Strength Path

★★★★★

First 5K to First 10K took me from barely jogging to finishing my first real race. I never thought I'd call myself a runner.

Sabrina

41 · Mother of Two · Running Path

★★★★★

Built to Perform fits perfectly around my work week. I'm stronger, I sleep better, and I actually look forward to training now.

Julian

29 · Marketing Manager · Hybrid Path

★★★★★

Shift work made consistency impossible until I found a plan that worked with just 3 days a week. Down 12kg and stronger than I've ever been.
