Years Coaching & Racing

You compete at a high level. Your coaching should, too.

Well-Fit is a fully personalized coaching relationship built around your schedule, your goals, and your physiology. A real coach who adjusts on the fly, analyzes your data, and pushes your limits systematically.

I specialize in triathlon coaching for:

The Executive Athlete

You travel constantly, your schedule shifts without warning, and every training hour has to earn its place. You need a coach who adjusts in real time — and does.

The Serious Age Grouper

You're chasing a Kona slot, a sub-10, or a PR that means something. You need more than a training plan — you need a coach who has been to that start line and knows what it takes.

Work with Sharone

Fully Personalized Training

Every week built around your current fitness, your schedule, and your target race. No templates. Your training is yours.

Direct Coach Access

Questions don't wait for a weekly check-in. You have direct access to Sharone before a hard session, after a bad week, or when travel blows up the plan.

Race Strategy & Execution

Course-specific preparation, pacing strategy, nutrition protocol — built around your actual fitness, not a generic calculator.

Performance Analysis

Advanced analysis of your training data, swim mechanics, bike fit, and run form. What's holding you back isn't always obvious.

Chicago In-Person Option

For athletes in Chicago: in-person sessions, track work, open water, and hands-on technical coaching alongside your remote program.

Wellness Integration

Performance and well-being are the same goal. Recovery, strength, sleep, and health markers are a major part of the system from day one.

"Sharone coached me for the better part of a year, mapping every day of training — thresholds, goals, race selection. I made real progress across swim, bike, and run, and finished my first Ironman 140.6 ready for the day. He's the reason I was prepared."

About Sharone Aharon

30 years of doing the work — and coaching others to do it.

Within my first 12 months of training, I went from barely swimming a length of the pool to finishing the Ironman World Championship in Kona — in the top half of the race. Not because I was naturally gifted. Because I was relentless about figuring out what worked. That relentlessness became a career.

I earned a Master of Science in Exercise Sciences from the University of Illinois, became one of a small number of coaches in the country to hold a USAT Elite Level III certification, and went on to coach with the USA Triathlon national program. In 2025 — at 60, after rebuilding my fitness from the ground up — I qualified for the Ironman 70.3 World Championship in Nice, France.

I'm not coaching you from the sidelines. I'm still in the race.
