Services launching at TAC
A preview of the services launching at TAC. Full details and booking will be available at launch.
Performance Plateau Assessment
For the athlete asking, “Why am I not getting faster?” A comprehensive evaluation combining bloodwork, a medical history review and physical (in-person or telehealth), nutrition and fueling review, training history and load analysis, sleep and recovery audit, RED-S / low energy screening, overtraining/chronic fatigue evaluation, and ventilatory and lactate testing — all integrated into one clear plan. Join the early access list.
Endurance Performance Bloodwork Consult
Athlete-centered bloodwork review via telehealth with practical interpretation for health and performance.
Cycling Performance Assessment
Ventilatory and lactate testing to define thresholds, training zones, fueling strategy, and aerobic efficiency.
Running Performance Assessment
Ventilatory and lactate testing to identify thresholds, training zones, fueling needs, and performance opportunities.
Triathlon Performance Assessment
Combined bike and run metabolic testing for sport-specific thresholds, fueling strategy, and integrated guidance.
Motocross Performance Assessment
Off-track metabolic testing across bike, run, and/or rower to establish training zones, plus an optional off-season plan with mid-season maintenance support.
Remote Performance Plateau Assessment
For athletes outside the Front Range: everything under our flagship service, without the in-person metabolic testing.

Common questions.
01Is TAC a coaching service?+
TAC is a performance testing and athlete health practice, but a limited coaching roster is available for athletes who want ongoing training guidance built on TAC's testing and data-informed lens. Most athletes come to us for testing, bloodwork review, and assessment — and we work alongside their coaches as a performance partner. Select coaching spots are offered to athletes who have completed TAC testing. Tyler is a USA Cycling Level 3 certified coach, and coaching at TAC stays grounded in the same physiology-first, data-informed approach as our assessments.
02Who is TAC for?+
Cyclists, runners, triathletes, motocross racers, and other endurance and power-endurance athletes who want a deeper, athlete-specific approach to health and performance.
03Will appointments be virtual or in-person?+
TAC will offer select virtual services along with in-person testing in the Denver metro area — including Denver, Thornton, and the surrounding Front Range communities within reasonable driving distance.
04Does TAC replace my primary care provider?+
No. The Athletes Clinic provides performance testing, bloodwork review, and athlete health education — we do not diagnose or treat medical conditions. TAC complements your primary care provider; athletes should consult their PCP for medical diagnosis and treatment.
05When will TAC launch?+
TAC is targeting a limited launch in fall/winter 2026 with a full service launch in early 2027. Services will roll out as we finalize practice operations.
