Why This 6-Time Ironman Winner Walked Away From Triathlon to Chase Fear
What compels a 6-time Ironman champion, with an impressive tally of 16 Ironman 70.3 titles, to leave the world of professional triathlon at the height of her career? For Heather Jackson, the answer lies not in defeat or burnout, but in an unyielding curiosity that refuses to see limits as endpoints.
In a world where athletes often specialize early and stick to one discipline for life, Jackson's bold transition from triathlon dominance to gravel racing and ultra running challenges everything we think we know about athletic careers and personal growth. Her journey from smooth roads to rugged mountain trails offers powerful insights for any endurance athlete wondering if there's more adventure waiting beyond their comfort zone.
Drawing from Jackson's decorated triathlon career and her recent adventures at UTMB Mont-Blanc and 12-hour gravel races, plus insights from her husband and coach Sean "Wattie" Watkins, this is your complete guide to successfully navigating sport transitions—and discovering why fear might be your most valuable compass.
The Psychology of Athletic Reinvention: When Success Becomes a Starting Line
Most athletes view fear as something to overcome. Jackson has learned to see it as something to follow. After dominating triathlon for over a decade, she made a decision that stunned the endurance world: she walked away from guaranteed success to pursue challenges that terrified her.
"I've always been super curious about trying new things," Jackson explains. "I see other people do something and I'm always like, can I do that? That looks crazy, or that looks so cool."
This curiosity-driven mindset represents a fundamental shift in how we think about athletic careers. While conventional wisdom suggests sticking with what you're good at, Jackson's approach reveals why versatility and challenge-seeking might be more sustainable paths to long-term fulfillment.
The Fear-as-Compass Philosophy
Jackson's transition wasn't driven by dissatisfaction with triathlon, but by a recognition that fear often signals growth opportunities. Her decision to step away from professional triathlon in 2022 came with doubt, but that doubt became clarifying evidence that something new was calling her forward.
"That element of challenge is 100 percent what motivates me," she says. The bigger the challenge, the more compelling it becomes—particularly when it forces her to confront what she once believed were her limits.
This mindset shift has profound implications for age-group athletes. Instead of avoiding disciplines that intimidate us, Jackson's example suggests we might find our greatest growth in exactly those spaces that make us question our abilities. For those looking to embrace your mid-life renaissance through endurance sports, this philosophy offers a powerful framework.
From Smooth Roads to Gravel: The Technical Transition
Jackson's move into gravel racing wasn't just about seeking new challenges—it was a strategic decision that actually enhanced her triathlon performance. Understanding how different disciplines complement each other is crucial for successful sport transitions.
Physical Adaptations for Variable Terrain
Gravel racing demands constant engagement that traditional road cycling rarely requires. Every pedal stroke on variable terrain builds strength, stability, and bike handling skills that translate directly to improved triathlon performance.
Key physical benefits include:
- Enhanced core stability from navigating rough surfaces
- Improved power output from constant micro-adjustments
- Greater mental resilience from unpredictable conditions
- Increased strength endurance from longer time in the saddle
Many gravel events are longer than even an Ironman bike split, which creates interesting training adaptations. Jackson notes that this extended time on the bike can make traditional triathlon distances feel more manageable, both physically and psychologically.
Equipment and Training Considerations
The transition to gravel requires specific equipment modifications and training approaches. Jackson emphasizes that while gravel builds incredible strength and endurance, specificity still matters for triathlon success—especially when it comes to maintaining efficiency in an aerodynamic position.
Smart periodization becomes essential when balancing multiple disciplines. Jackson recommends viewing gravel as complementary training during triathlon base-building phases, while maintaining discipline-specific work closer to key races.

Ultra Trail Running: When Limits Become Thresholds
Jackson's experience at UTMB Mont-Blanc—a brutal 170km mountain ultra with 10,000m of climbing—provided the ultimate test of her new philosophy about limits and growth.
The Mental Game in Ultra-Distance Events
"It was the first time I was so challenged," Jackson reflects on UTMB. "I quit thousands of times out there. I went through so many moments of doubt, because I truly thought I was at my limit."
But here's where Jackson's experience offers crucial insight: those moments of wanting to quit weren't signs of failure—they were thresholds to move through. The race taught her that limits are often not endpoints, but places you pass through rather than stop.
Nutrition and Pacing Strategy Differences
Ultra trail running requires completely different approaches compared to triathlon:
- Nutrition flexibility: Mountain conditions demand adaptability over rigid fueling plans
- Pacing patience: Ultra events reward conservative early pacing and negative splitting
- Mental preparation: Expecting and planning for low points becomes crucial
- Environmental factors: Weather, terrain, and altitude create variables absent in triathlon
For optimal performance in ultra-distance events, proper electrolyte supplementation becomes even more critical than in traditional triathlons.
Preparation for the Unknown
Unlike triathlon, where conditions are relatively predictable, mountain ultras present constant unknowns. Jackson's preparation focused less on controlling variables and more on building adaptability—a skill that translates to improved race-day performance in any discipline.
Practical Transition Strategies for Age-Group Athletes
Jackson's experience provides a roadmap for athletes considering their own sport transitions. Her approach balances adventure-seeking with smart training principles.
Making Gravel Work for Triathlon
Seasonal Integration: Use gravel events during triathlon off-season or base-building phases. The strength gains and mental break often lead to stronger triathlon performances.
Strength Building Benefits: Variable terrain engagement builds functional strength that gym-based training often misses. Jackson emphasizes how this translates to better power output and efficiency on triathlon courses.
Maintaining Specificity: While gravel provides excellent cross-training, maintain triathlon-specific position work and brick training for optimal performance transfer. Learn more about AI-powered training approaches that can help balance multiple disciplines.
Choosing Your Next Challenge
- Follow curiosity: "I see other people do something and I'm always like, can I do that?"
- Embrace fear: If it doesn't scare you a little, it might not provide enough growth stimulus
- Start smaller: Build confidence with shorter events before tackling ultra-distances
- Involve your support network: Jackson credits Wattie's encouragement as crucial to taking that first step

The Joy Factor: Don't Forget Why You Started
Above all, Jackson emphasizes that joy isn't a bonus—it's essential for long-term endurance success. She lights up describing how Wattie rides with their dogs Frankie and Stevie, and how she added a basket to her gravel bike to bring them along.
"That's usually the hardest part," she notes about making transitions. "Taking that first step." But when that step leads to shared adventures and renewed passion, the difficulty becomes worthwhile.
Common Transition Pitfalls and How to Avoid Them
Learning from Jackson's experience and coaching insights, here are key mistakes to avoid:
The Specificity Trap
Problem: Abandoning sport-specific training entirely for new challenges
Solution: Maintain discipline-specific work while gradually adding new elements
Expectation Management
Problem: Expecting immediate success in new disciplines
Solution: Embrace the beginner's mindset and focus on learning over performance
Burnout Risk
Problem: Taking on too many new challenges simultaneously
Solution: Transition gradually, allowing proper adaptation between phases. Consider using heart rate monitoring technology to prevent overtraining.
Community Disconnect
Problem: Losing connection with existing training partners and support systems
Solution: Find ways to involve current community in new adventures, or build bridges between old and new networks
The Future of Multi-Sport Athletes
Jackson's journey reflects a growing trend in endurance sports: the rise of versatile athletes who refuse to be confined by single-discipline thinking. This approach offers several advantages:
- Injury prevention through varied movement patterns
- Mental freshness from novel challenges
- Skill transfer between complementary disciplines
- Career longevity through sustained motivation
Her success suggests that the future of endurance sports may favor curiosity and adaptability over pure specialization. Athletes like Chris McCormack taking on trail running demonstrate this trend among elite athletes.
