MH Squad coach, CrossFitter, powerlifter and founder of worldwide charity fitness Battle Cancer, Scott Britton is back at it again pushing the edges of his fitness and sharing his learnings. After his last outing – testing the limits of his CrossFit training to see if it was enough to get him through a brutal Ironman triathlon – Scott wanted to see how far he could stretch the hybrid athlete spectrum, attempting to compete at a major CrossFit competition, then following it up with a PB attempt at the Miami Marathon. All in the same week. Let’s see what we can learn from Scott’s pain.
I wanted to test the limits of my status as a hybrid athlete – not just hitting a lift before a run but fully committing to two intense tests of fitness back to back. My last challenge, completing an Ironman triathlon, left my strength levels slightly depleted – not ideal ahead of a huge CrossFit competition – so I decided that it was time to slam the creatine and measure just how quickly I could regain strength and maintain muscle, while at the other end of the spectrum also aiming to set a new personal best in the marathon.
Compete at Wodapalooza – a three-day CrossFit event featuring heavy lifting, gymnastics, and hardcore functional workouts – then, just six days later, take on the Miami Marathon, beating my previous time over 26.2 miles.
This was a true test: integrating heavy lifting and high-intensity Zone 5 workouts while also building my Zone 2 endurance and leg conditioning for a faster marathon.
After completing the Ironman, I had shifted to recovery and rebuilding strength. But preparing for an elite CrossFit competition required a whole new level of intensity. The first three weeks were brutal: pain in my wrists, hips, and shoulders as I adapted to the demands of heavy barbell lifts and high-rep gymnastics. My body had become accustomed to long, steady efforts, not repeated all-out sprints.
My legs took a beating: more squats, more weight, and more lactic acid buildup. On my long runs, microtears in my quads and calves reminded me how hard it would be to balance these two contrasting disciplines. I had to adjust my diet, increasing protein and fats for muscle repair, while cutting the excessive carbs I no longer needed for six-hour endurance sessions.
The strategy was simple: balance my heart rate and my legs.
My marathon plan included three weekly runs:
This approach built endurance while keeping my heart rate high in preparation for Wodapalooza.
Strength and CrossFit training were relentless: daily lifting, followed by gymnastics and high-intensity metcons. Once a week, I simulated competition conditions with strict timing.
A major change I noticed post-Ironman was that my current prep didn’t require the same carb-loading as ultra-endurance training. I needed more protein and fats to prepare my joints and help my muscles recover.
I also reintroduced one supplement I had avoided for six months: creatine. I knew my muscles needed stored energy to handle the workload, but I wanted to avoid the bloating and water retention I had experienced in the past with powdered creatine. So, I tried something called ‘liposomal creatine’.
Liposomal is a type of nutrient delivery system that encapsulates substances in tiny, spherical vesicles made of lipids (fatty acids). In theory, this protects the nutrients from degradation and improves their absorption and bioavailability.
I used a brand called RHO Creatine and took it daily. Within a month, I had gained 1.5 kg, was squatting 95% of my previous max, and – most importantly – felt no bloating when running. Over two months of preparation, I added 2.5 kg of muscle while running more than 30 km per week.
Before the big event, my teammates Aaron and Gabe and I trained with CrossFit elites like Noah Ohlsen, Chandler Smith, and Travis Mayer. We drilled transitions, worm cleans, and competition-level lifts to prepare our bodies for the intense demands ahead.
Fast forward to Miami Beach, where we checked into our Airbnb, stocked up on food, and finalised our game plan – only to face the coldest temperatures in Miami’s recorded history. On day one, we were warming up on the beach in four layers of clothing.
Then, disaster struck.
Due to a technical issue with the speaker system, we missed our heat call for the first event. Sprinting to the competition floor, we were told we couldn’t start – last place, zero points. In seven years of competing, I had never missed a heat, and now I stood on the sidelines, fuming.
There was no time to dwell on it. Event two, a brutal overhead squat workout (30-20-10 reps, increasing weight), was up next. Despite the cold, I hit 16 reps at 85 kg and 13 reps at 102 kg, proving my legs could still handle the load.
That evening, we received an unexpected call: Wodapalooza officials offered us a chance to redo our missed event – at 7 am the next morning. That meant a three-workout day, starting with a 5 am wake-up call to fuel up, stretch, and hit the beach for worm clean and jerks and Echo Bike sprints.
Day two was electric. Under the Miami lights, we pulled sleds in the sand, nailed muscle-ups, and climbed the leaderboard. Day three ended with one of the toughest workouts I’ve ever done in competition: The 3/3/3/4.
Every three minutes, as a team, we completed:
I pushed my 400m splits under 1:40 and battled through heavy dumbbell work in the sand, collapsing at the finish. Mid-table finish at one of the world’s hardest CrossFit competitions – mission accomplished.
On Monday, I felt surprisingly okay, managing a light shakeout run. But by Tuesday, I was sick – a full-blown cold, dizziness, and coughing fits.
Here’s where I learned the biggest lesson of this entire challenge: even with the best preparation, you can’t control everything. I went for an 8-mile run, hoping to clear my lungs – bad idea. It made me worse and got in my head. Months of training, nutrition, and focus felt wasted.
So, I switched to operation survival mode:
The real battle wasn’t physical, it was mental. Could I still push through? Could I let go of expectations and focus on simply finishing?
Come race day I could finally breathe properly, and the dizziness had subsided. Along with 19,000 other runners, I lined up at Bayfront Park, questioning whether my legs would hold up.
The first challenge? The sheer number of people overtaking me. But as I settled into my pace, I started catching them back, finding my rhythm.
At mile eight, my lungs felt normal. At mile 16, the bridge climbs slowed me down, but I allowed myself two miles to recover before building toward a strong finish.
Then came something I’d been dreading: bladder pain. I’d encountered it previously due to dehydration and should have learned from my Ironman. In 25-degree heat, I sweat excessively. At each aid station, I doubled my water intake and, after 40 minutes, luckily, the pain subsided.
The final two miles I got into pure CrossFit mentality. I wanted a PB. I wanted to finish strong. I cranked up my playlist – hitting the pavement hard to the Architects and Bring Me the Horizon – ignored the pain, and pushed my mile splits.
I sprinted across the finish line in 4.41, securing a 19-minute PB.
Did I win Wodapalooza? No. Did I set the running world alight with my marathon time? No.
But I learned something invaluable: by fully committing and refusing to sacrifice one goal for another, I could successfully complete two vastly different challenges.
It wasn’t easy. It required careful planning, adaptability, and an environment that supported both disciplines. But it also proved that I can exist in multiple worlds – and so can you.
Can you be a parent and a business owner? Hell yes. Can you work full-time and coach a rugby team? Absolutely. Can you shift your fitness goals to accomplish something deeply personal? The question isn’t can you; it’s why aren’t you?‘
