Karleen Dirmantas   BSRX3 Your Prescription for Speed Triathlon and Multisport Coaching

If you’re looking to improve as an athlete and take your training to the next level, consider requesting a BSRX3 coach. Our goal is to enhance your training and racing experience by working with you one-on-one, providing a fully personalized and customized program. We don’t offer bronze, silver, gold and platinum programs. We only offer one program. Yours! Your coach won’t limit communication or program adjustments.


Karleen specializes in working with athletes of all levels and develops custom programs tailored to their goals. She understands life balance with work, family and training, and finds a ‘happy medium’ that works.
Since competing in swimming in her youth, in 2007 she decided to race in her first sprint triathlon. She has had the triathlon bug ever since! Within 3 years she was competing as a high-level age group athlete in the sport. Karleen focuses each year on getting stronger physically and mentally.
