After being diagnosed with MS, he started running marathons. It’s helping reverse the disease’s progression.
When Derek Stefureac was diagnosed with multiple sclerosis, a chronic disease that affects the central nervous system, he was a smoker who never exercised.
Everything changed when he had an “attack” at work when he was 39: His body seized for about a minute, and Stefureac told CBS News that he “thought he was dying.” After seeing multiple doctors, he was diagnosed with multiple sclerosis.
“It was a pretty scary diagnosis, and I wasn’t even sure what it was, to be honest. I didn’t know anyone who had it,” Stefureac, now 51, said. “As I learned more, a doctor said, ‘It’s a progressive disease, it’s incurable. We have some therapies to slow down the progression, but the best thing you can do is get healthy. A healthy body is the best tool.’ So that scared me enough to quit smoking, and as part of quitting smoking, to help me out and get healthy, I just started jogging.”
Now, 13 years after his diagnosis and those initial jogging sessions, Stefureac has run 36 marathons — including one in Antarctica and one on Mount Everest. After completing Australia’s Brisbane marathon earlier in June, he’s now run a marathon on every continent. He’s built a community of runners, connected with others with his condition and his doctor says he’s even managed to reverse the progression of his multiple sclerosis.

What is multiple sclerosis?
Multiple sclerosis is a disease that affects the central nervous system, according to the Mayo Clinic’s website. The immune system attacks the myelin, or protective sheath, that covers nerve fibers. That causes communication problems between the brain and the rest of the body, causing a wide range of symptoms including numbness and weakness in the body, an unsteady gait, blurry vision and more. Eventually, it can cause permanent damage or deterioration of the nerve fibers.
Multiple sclerosis is “an unpredictable disease,” said Dr. Bruce Bebo, the executive vice president of research at the National MS Society, who is not involved in Stefureac’s care.
For Stefureac, who also takes medication to manage his condition, the disease most prominently manifested as a dragging foot that he noticed when he began jogging. Dr. Le Hua, a neurologist overseeing Stefureac’s treatment, said he also had neurological dysfunction and some numbness, weakness and tingling in his body. He also had spinal lesions, which are “associated with a higher risk of disability” from multiple sclerosis, she said.
How does exercise impact multiple sclerosis?
Bebo said that a growing body of evidence supports the importance of exercise and other healthy lifestyle choices in helping treat multiple sclerosis. Even if exercise isn’t reversing the disease’s progression, it can help limit co-morbidities like high blood pressure that can accelerate the progression of multiple sclerosis. Exercise can also help promote plasticity of the nervous system, which can improve function and compensate for damage caused by multiple sclerosis, he said.
Cardiovascular training like running can be especially helpful for managing multiple sclerosis, Bebo said, but a person doesn’t necessarily have to be running marathons to see the benefits.
“There’s pretty much something for everyone, no matter what their level of ability or disability is,” Bebo said.
Hua said that Stefureac’s case is “really unique” because he has actually seen signs of “disability improvement,” where some difficulties he initially faced have gotten better. Many people may see signs of disability slowing, she said, but an actual improvement in disease progression not something she or others in her field see often.
“Derek actually looks a lot better now than he did when he was first diagnosed in terms of disability,” Hua said.
Stefureac told CBS News that he “doesn’t even remember” the last time he dealt with a symptom of multiple sclerosis.
“I only think of MS when I have to refill my prescription or make an appointment,” he said.

After running a marathon on every continent, what’s next?
Stefureac has completed his goal of running a marathon on every continent, but there are still more extreme events he wants to compete in. He’s looking at a marathon in the North Pole, and running one on Tanzania’s Mount Kilimanjaro in February 2025. He also wants to participate in more intense events like a five-day race across the Sahara Desert and an Ironman Triathalon in Hawaii.
“When I started, the goal was to get myself in shape and slow this progression down, and it has worked so, so amazingly,” Stefureac said, adding that he hopes his story can serve as an inspiration for other people dealing with multiple sclerosis or chronic health conditions.
“It sounds insane, but for me, I’m grateful for the diagnosis. It really was an eye-opener, and it turned my life around. I don’t think I’d be doing seven continents if I never had been diagnosed with MS,” Stefureac said. “No one could ever know I have MS. People are shocked when I tell them. I’d like to be a good example of like, ‘This could be you.'”

U.S. Air Force gives update on new B-21 stealth bomber: “Nobody on the planet can do what we’re doing”
Air Force leaders gave an update on the B-21 Raider, a futuristic aircraft that is expected to become the United States’ next nuclear stealth bomber.
The aircraft can deliver both “conventional and nuclear munitions,” according to a news release from the Air Force, but will be “critical to deterring conflict” around the world. Gen. Thomas Bussiere, commander of the Air Force Global Strike Command, said the stealth bomber will help the United States keep pace with threats worldwide.
“We are the free world’s only bomber force. … Nobody on the planet can do what we’re doing right now,” Bussiere said, adding that there will likely be an increased demand for the support the stealth bomber can provide in the coming years.
Air Force Global Strike Command
Currently, the stealth bomber remains in the test flight stage, and is doing two such flights a week, according to Thomas Jones, the Northrop Grumman Aeronautics Systems sector president. A photo shared by the Air Force shows one of the bombers during flight testing.
“We’re really starting to strike up quite a cadence … when we started this journey, we made a vow that we were going to design this system to be a daily flyer,” Jones said, according to the release. “It’s been a phenomenal year of progress, and we hope to continue that through the next year.”
A recent notable test confirmed the stealth bomber’s structural design and integrity, according to officials. The plane is now going through a fatigue testing campaign.
Once the planes are tested, some of the aircraft will be delivered to the Ellsworth Air Force Base in South Dakota to help train Air Force squadrons on the stealth bomber. When the B-21 enters the service, this site will be the main operating base for the stealth bomber.
Whiteman Air Force Base in Missouri will be a secondary base, and Dyess Air Force Base in Texas a third.
The stealth bomber is set to replace the B-1 Lancer and B-2 Spirit bombers in the Air Force’s fleet.

Whether you’re barreling down a mountainside or taking a leisurely ride along your local trail, a great mountain bike is key. But what exactly does a great mountain bike look like, in terms of features? It depends on the kind of terrain and riding style you do.
The best mountain bike for long, cross-country rides will have very different specs than a downhill bike. Some offer full suspension for a smooth ride on bumpy trails. Some have wider tires that are better at gripping wet or sandy terrain. Some are designed for maximum pedaling efficiency and serious stopping power so you can climb steep mountainsides without wearing yourself out. No matter where you and your new bike are headed this fall, we’ve rounded up the best mountain bikes for every rider and every terrain in 2024. Don’t forget to strap on your bike helmet.
Best mountain bike for beginners: Giant Talon 29 1
Mike’s Bikes
The Giant Talon 29 1 is a solid entry-level mountain bike at a reasonable price point. With its balanced frame geometry and high-traction tires, it’s great for a comfortable, stable ride on most trails.

With 80mm to 100mm of suspension travel, this hardtail mountain bike strikes that perfect balance of pedaling efficiency and shock absorption.
Riders can also adjust the suspension within that range by adjusting the air spring and the rebound damping. That gives you improved steering precision and a better ride feel since you can tailor it to your needs. If you’re a beginner, it may take some trial and error to fine-tune those settings, but playing around with them is a great way to learn how suspension impacts your ride.

What type of mountain bike should a beginner get?
The best mountain bike for a beginner is a balanced, versatile one. Since you’re probably not tackling steep inclines and declines yet, opt for a trail bike that offers great traction, strong brakes and easy maneuverability along bumpy, muddy trails. That means grippy tires and responsive steering so you can confidently control your bike over tree roots, up hills and on descents.
If the trails you’re eager to go on are largely uphill, look for a bike that’s lightweight with a firmer pedaling platform. Those two features will improve climb efficiency so you’re not wearing yourself out on those uphill stretches.
Do I need a full-suspension mountain bike?
You don’t need a full-suspension mountain bike, but they are nice to have. Unlike hardtail mountain bikes, which only have suspension in the front, full-suspension mountain bikes have suspension in both the front and rear. That extra suspension helps absorb shock, cushioning the impact as you hop over bumps or navigate downhill jumps and drops.
That cushier feel can be nice even on milder trail rides, but they tend to be significantly more expensive and require more maintenance than a hardtail mountain bike. So it might not be worth the extra expense and care if you don’t usually do technical trails or downhill riding.
