Making sure your heart is healthy for the Covenant Health Knoxville Marathon
KNOXVILLE, Tenn. (WATE) — Preparing your body for the Covenant Health Knoxville Marathon is a job in itself, and making sure your heart's health is in its prime condition will help you well beyond the 26.2 miles of the race.
6 News's Stan Smith spoke with a cardiologist to get advice about how to make sure your heart is in the right condition to compete.
Nonprofit training and empowering young runners in East Tennessee
Whether you're running to earn a spot on the podium at the Knoxville marathon or leisurely competing to knock this off your bucket list, running 26.2 miles is not for the faint of heart. Making sure your heart is in good shape for the marathon is something that you should take into account.
'You know, being healthy and being active can mean a lot of different things for different people. So, if you are someone who doesn't do any activity, starting slow is important. And as the American Heart Association preaches — and I completely agree with — 30 minutes of something every day is activity,' said Dr. Briana Costello, a cardiologist with fort sanders, and an avid runner herself.
She says there are so many ways to prepare yourself to ensure your heart is able to keep up on race day.
'So, if you're going from zero to 100, you want to make sure you get some time for rest in there,' she said. 'From a cardiac standpoint, we really push 150 minutes of activity a week. So again, if that's walking or if it's Zumba or swimming or jogging, whatever that is, getting those minutes in will reduce your risk of heart disease, stroke, heart attack and death.'
As for other ways to keep your heart in shape along with the rest of your body, Dr. Costello said to make sure you drink plenty of water and have the right amount of electrolytes and calories because those act as fuel to keep your heart pumping.
According to the CDC, one in 20 adults aged 20 years and older have coronary artery disease, so if you're unsure about where your heart health stands, Dr. Costello advises you to schedule an appointment with your doctor to see if running long distances is right for you.

'If you're not sure, is my blood pressure too high, or do I need to go see someone to talk about my blood pressure or my cholesterol or my diabetes? You know, getting into your primary doctor or a cardiologist who can kind of help further risk stratify you and guide you on your health journey is super important. Doing that early and being preventive is so much better than being reactionary and having to do, you know, secondary measures for preventing another heart attack or stroke.'
Don't worry if you aren't able to make it out to the event. We've got you covered right here on 6 News. Our team is bringing you race coverage this week, and Sunday we'll be spread out along the racecourse bringing you live updates from the marathon all morning.

Hawai'i's CPR training campaign launched by Heart Association
HONOLULU (KHON2) — The American Heart Association Hawai'i is rolling out its first-ever Community Impact Days this week, aiming to empower residents with life-saving CPR skills during CPR and AED Awareness Week, observed from June 1 to 7. Spectra Fest bringing the community together AHA Hawai'i's Community Impact Director Elizabeth Cotterell, alongside Dory Clisham, training manager at American Medical Response, spoke about the initiative with Chris Latronic live from the AHA headquarters on Richards Street. The campaign focuses on Hands-Only CPR training, particularly important as children head into summer and spend more time away from trained adults like teachers and coaches. The push comes with a sobering statistic: more than 350,000 people suffer cardiac arrest outside of a hospital each year in the U.S., and about 70% of those incidents occur at home. Without immediate intervention, 90% of these cases are fatal.'CPR can double or even triple someone's chance of survival,' Cotterell said. 'And kids as young as 9 years old can learn it.' As part of its centennial year, the American Heart Association is calling on every family in Hawai'i to help build a 'Nation of Lifesavers'—a movement to ensure that anyone, anywhere is ready to respond during a cardiac emergency. The organization has set an ambitious goal: double the survival rate for cardiac arrest by 2030. Free Hands-Only CPR training sessions will be held this Saturday, June 7, at the Waimānalo Health Center, open to all members of the community.

NFL safety Justin Reid expands CPR education for youth through summer program
( NewMediaWire ) - June 05, 2025 - KANSAS CITY, Mo. — More than 350,000 cardiac arrests happen outside hospitals in the U.S. each year. Most don't receive the cardiopulmonary recitation (CPR) they need to survive. NFL player Justin Reid is tackling that reality through a new program pairing CPR training with a summer camp. Through his Kansas City based JREID Indeed summer program, the former Chiefs player, now with the New Orleans Saints, is expanding his American Heart Association Nation of Lifesavers Player Ambassador role. As an ambassador Reid is helping the Association, a global force changing the future of health for all, and its Nation of Lifesavers (TM) movement double cardiac arrest survival rates by 2030. In honor of National CPR and AED week happening June 1-7, Reid brought Hands-Only CPR education to the 35 high school students participating in JREID InDeed's summer program, called Tackling Tech. Yesterday, participants learned the correct rate and depth of compressions to save a life. Compression-only CPR, known as Hands-Only CPR, can be equally effective as traditional CPR in the first few minutes of emergency response. It is as simple as calling 911 if you see a teen or adult suddenly collapse and then push hard and fast in the center of the chest. 'It is important for me to participate as a Nation of Lifesavers Player Ambassador and to educate more Americans about how easy it is to learn Hands-Only CPR. The person you save is likely someone you know and love,' said New Orleans Saints player and founder of JREID InDeed, a nonprofit organization focused on empowering under-resourced communities, Justin Reid. 'Tying together the Tackling Tech program with CPR education is an honor. But, challenging them to find a solution to help others remember the lifesaving skill is how we are changing outcomes - one training at a time.' Reid has served as Nation of Lifesavers Player Ambassadors since the start of the 2024 National Football League (NFL) season Reid issued a challenge to the summer program participants. The goal was simple. Take the CPR skills they learned and help others learn. Reid asked them to create a fun and engaging way to expand their new CPR knowledge to students across the country. Now as the summer continues, the participants are developing unique school and student friendly dances to help others learn the steps in the chain of survival. The American Heart Association's in-school programs Kids Heart Challenge (TM) and American Heart Challenge (TM) will take these TikTok style dances to school assemblies to help youth remember the two steps to save a life in a fun and active way. 'CPR education is crucial to saving lives and improving outcomes in a cardiac emergency,' said Nancy Brown, chief executive officer of the American Heart Association. 'Finding ways to meet people where they are and bring this lifesaving skill to more people is empowering communities to act fast and be ready and able to respond with the lifesaving skill of CPR. Justin's work and the engagement of his summer camp kids is a great example of how we can all play a role in expanding CPR education to make a difference when seconds matter.' The American Heart Association is the worldwide leader in resuscitation science, education and training, and publishes the official scientific guidelines for CPR. With nearly 3 out of 4 cardiac arrests outside of the hospital occurring in homes, knowing how to perform CPR is critically important. When more people are ready to perform CPR, the chance for a positive recovery increase for the community.
