Following the event, he learned he has a genetic predisposition to increased arterial plaque and inflammation, and that keeping an eye on the blood biomarkers tied to cardiovascular health is essential for him. InsideTracker is proud to partner with Tim to help him both fine-tune nutrition and lifestyle for performance as he strives to again qualify for the IRONMAN World Championships in Kona and also keep an eye on the biomarkers that are vital for longevity and cardiovascular health.   #### Save 20% off when you sign up! ## How it Works - ![step icon](https://info.insidetracker.com/hubfs/step-icon-1.svg#step1) Step 1 ##### Get tested Pick your plan and have your blood tested.
