At the age of 32, Tamara Jewett, the 15th-ranked athlete in the PTO and a powerhouse in the triathlon world, is venturing into the daunting realm of full-distance Ironman races. Known for her unparalleled run splits in the 70.3 circuit, Jewett is now setting her sights on the ultimate endurance test in triathlon: the full 140.6 miles.

Since her rise in 2021, Jewett has dominated the 70.3 distances, outpacing 92% of her competitors with a run that’s nearly unmatched, second only to Ashleigh Gentle. As we look toward 2025, she’s poised to challenge her own limits and redefine her career by stepping up to the full Ironman distance. This move isn't just a step up; it's a leap into a new chapter that could reshape her career and influence the sport.

Why the Shift to Full-Distance?

Jewett’s decision wasn't spontaneous. It was a calculated move fueled by a blend of curiosity, strategic career planning, and perfect timing. On her Instagram, she shared a candid insight:

“My tummy tells me that now is the right time to try out this full-distance Ironman thing.”

Here’s why she’s making the move now:

1. Persistent Curiosity: For two years, Jewett has been intrigued by the challenge of a full marathon after a grueling bike ride. Her consistent 4:15/km pace in 70.3 races hints at her potential for the longer distance.
2. Strategic Career Move: Opting out of the T100 series, Jewett is seeking new challenges and flexibility in the IRONMAN Pro Series.
3. Optimal Timing: At 32, she is at the intersection of peak physical fitness and mature race strategy, making it the ideal time for this new challenge.

2025: A Year of Bold Moves

Jewett’s 2025 race calendar is as ambitious as her goals:

• April 5 – IRONMAN 70.3 Oceanside: She aims to defend her title and course record.
• April 26 – IRONMAN Texas: Her debut in the full-distance arena, coinciding with her birthday. She quips, “What better birthday gift to myself than a test of endurance in The Woodlands?”

Summer and Beyond

• Mid-Summer: Participation in select 70.3 races to fine-tune her form.
• July 20 – IRONMAN Lake Placid: A course that mirrors the challenging conditions of Kona.
• October – Kona: A podium finish in Texas could secure her a spot at the prestigious IRONMAN World Championship.

Training Adjustments and Lifestyle Changes

1. Increased Training Volume: Her training now includes a 20% increase in run and bike mileage.
2. Bi-Coastal Living: Splitting her time between San Francisco and Toronto allows her to maintain her training regimen while managing personal commitments.
3. Enhanced Swim Training: With the challenging swim at Lake Placid in mind, Jewett is focused on strengthening her swim to conserve energy for the bike and run.
4. Nutritional Strategy Overhaul: Aiming for over 400 kcal/hour to sustain energy throughout the marathon segment.

Impact on Women’s Long-Course Triathlon

• New Standards: Her exceptional running ability could set new benchmarks for marathon times in full-distance races.
• Inspiration for Runners: A successful transition could encourage other runner-first triathletes to consider long-course triathlons.
• Kona Implications: A strong performance in Texas could make her a wildcard contender at Kona, challenging established athletes with her speed and endurance.
