- Lucy Charles-Barclay’s Training Routine
Lucy trains across all three triathlon disciplines with intense weekly volumes and tailored intervals. A typical week includes five to six swim sessions, four bike sessions (with long rides and FTP intervals), and several structured runs, including track intervals and long aerobic sessions. She also includes two to three strength sessions weekly to support injury prevention and power output
In an interview with Women’s Health, Lucy shared her intense training routine for Ironman competitions. She structures her Ironman prep around a high-volume, high-intensity regimen designed to improve endurance, strength, and race-specific performance. Each day targets different disciplines with thoughtful layering of workouts:

- Purpose: Ease into the week with technique-focused swim and light gym work for recovery after weekend volume
Tuesday (High-Intensity Run & Key Swim)
- Morning run: Warm-up jog
- Main set: 4–5 km intervals (track or treadmill) or continuous effort up to half marathon pace
- Followed by a 60–90 min easy cycle (Zone 2)
- Evening Swim: 2-hour club session with endurance and speed sets
- Purpose: Build run speed, aerobic base, and swim strength; ensure adequate fueling throughout this demanding day

- Purpose: Combine strength and aerobic work while introducing controlled intensity
Saturday (Speed Run & Recovery Ride)

Lucy Charles-Barclay’s Nutrition Plan
Lucy Charles-Barclay follows a highly disciplined nutrition strategy designed to optimize endurance, recovery, and gut comfort throughout her Ironman races. She typically consumes 60–70 grams of carbohydrates per hour on the bike using a mix of energy bars and drinks. For hot-weather races like Kona, she increases that intake to over 100 grams per hour to compensate for higher energy demands and sweat loss.
Her hydration strategy includes drinking three to four bottles of electrolyte solution during the bike leg and a dose of caffeine via Red Bull in the final stretch—decanted into small vials for convenience. The night before a race, she favors low-fiber, carbohydrate-rich meals such as pasta. On race morning, she opts for a familiar and easily digestible breakfast of porridge, toast, and tea, along with an electrolyte drink and sometimes a gel just before the start.
To stay on track during the event, Lucy sets a timer to eat every 30 minutes and drink every 15 minutes. She starts with solid foods like bars on the bike and switches to energy gels during the run, spacing about six evenly throughout the marathon. After the race, she begins her recovery with a protein shake and fluids, and when her appetite returns, she often enjoys pizza.
This full strategy—including fueling amounts, product choices, and scheduling—was outlined in her interview with 220 Triathlon, where she also emphasized the importance of testing all nutrition protocols during training to avoid surprises on race day.
Lucy Charles-Barclay on Motivation
After suffering a stress fracture in her hip early in 2022, Lucy Charles-Barclay was forced to pause her race calendar and face one of the biggest uncertainties of her career. As speculation swirled and critics voiced doubt about her ability to return to form, she heard whispers suggesting her best days were behind her. “She’s never gonna come back as good as she was,” people said. But instead of letting those words erode her confidence, Lucy used them as fuel. “All of that external noise… it just motivated me,” she told Red Bull in an interview, transforming doubt into drive. The injury became more than just a physical hurdle—it turned into a defining test of her mindset, her patience, and her will to fight back.
What makes Lucy’s comeback so powerful isn’t just that she proved everyone wrong by winning the 2023 IRONMAN World Championship in Kona—it’s that she did so with grace, clarity, and an inner fire stoked by criticism. She didn’t rush the process. She committed to smart rehab, stayed connected to her goals, and doubled down on mental strength. For Lucy, the skepticism surrounding her recovery wasn’t a setback—it was a challenge she accepted. And in answering it, she didn’t just reclaim her spot at the top of the sport; she redefined what resilience in elite competition looks like
