More people in the U.S. are being diagnosed with tick-related diseases every year, but we don't have to let that stop us from getting outdoors.

At home in Brooklyn, New York, my wife and I have discovered ticks on our dog, a pit-boxer mix who lacks the wherewithal to notify us of such an intruder. A few weeks ago, I found a tick—luckily, before it bit—on my arm while visiting Oakland, California. Outside editors have been coming across the disgusting creatures in northern New Mexico, northern Virginia, and coastal Massachusetts.

A decade ago, my little sister contracted Lyme disease in high school, so I have always been paranoid about tick bites. And with growing tick populations, ever more tick-related diseases, and a flurry of headlines about both, I’m sure I’m not alone.

There are hundreds of species of ticks, but the one to be most concerned about in the United States is Ixodes scapularis. The hard-body tick, also known as the blacklegged tick or deer tick, is a vector for a handful of diseases, including Lyme. “It causes far and away the most trouble in terms of health,” says Dr. Peter Krause, a senior research scientist with a specialty in epidemiology and infectious diseases at Yale Medicine.

Ticks are experiencing a largely unwanted glow-up in our current times. The largest vector-borne disease today is still Lyme, says Alison Hinckley, epidemiologist with the Centers for Disease Control and Prevention’s (CDC) Division of Vector-Borne Diseases in Fort Collins, Colorado. She cites a 2021 estimate based on insurance records that shows 476,000 Americans are diagnosed and treated for Lyme disease each year, which can cause headaches, muscle aches, joint swelling, severe fatigue, and even neurological symptoms. (As a point of comparison, only about 2,000 cases of Rocky Mountain spotted fever are reported each year in the U.S.) The reasons for the rise in Lyme range from deer populations to climate change. It’s enough to make me consider trading my hiking boots for gym trainers.

But if we stay inside, the bugs win. So we spoke to some experts to learn why ticks are prospering, what we can do about it, and how to continue to exercise outside safely. The good news? You can take precautions no matter your outdoor sport of choice, and finding a tick doesn’t have to be a five-alarm emergency.

According to the CDC, there are ticks in every state, though different species (carrying different diseases) proliferate in different environments. For instance, the lone star tick, named for a white spot on its back, is often found in Texas, and the brown dog tick thrives in Arizona. Lyme hails from Krause’s home state of Connecticut—it was named for the town of Old Lyme, in the state—but he might also encounter wood ticks and brown dog ticks, which can both transmit Rocky Mountain spotted fever. It’s not very common, he says, but the disease can cause fever, nausea, muscle pain, and a host of other scary symptoms. Despite its name, the lone star tick can also be found in Connecticut (it’s prevalent elsewhere on the East Coast, too, and in the southeastern and south-central United States), and can transmit an infection that leads to Alpha-gal Syndrome, which sometimes causes a permanent allergy to red meat. And that’s just one state. Another tick-borne disease, Babeosis, used to be called “Nantucket fever,” because one of the first cases in America was found on the nearby Massachusetts island in 1969. The Gulf Coast, American dog, and winter ticks transmit different pathogens around the country. You can see what ticks live in your state on the CDC website.

Still, the majority of tick-borne illnesses in the United States are Lyme disease. Ticks have a three-stage life cycle, Krause explains. As larvae, ticks feed on small mammals like mice. If these mammals are carrying Lyme-causing Borrelia bacteria, the tick is now infected and can transmit the disease. The “bloodmeal” (yum!) allows the larvae to molt into its next stage, when it is known as a nymph. At this point, if a nymph feeds on a human, the human will become infected.

Climate change is a major factor in the rise in tick diseases. Ticks need temperate, moist climates—they’ll die if it’s too hot, cold, or dry. Global warming, Krause says, is increasing tick habitat, with more areas becoming warm and humid. Given the southern states are experiencing hot, dry weather, they might have a temporary decrease in tick populations, but that hasn’t yet been shown, he says.

As a point of proof, Krause points to our northern neighbor. Canada was not historically home to Lyme-carrying tick populations, but now sees many cases of Lyme each year, due to both climate change and tick migration. Deer ticks, predictably, travel on the backs of deer and other furry creatures, but they can also attach to birds, Krause says, allowing them to establish a new colony hundreds of miles away.

The second factor that might be fueling today’s tickflation is deer distribution. Adult ticks use deer as all-you-can-eat mating hotels, and a single deer can host hundreds of ticks, Krause explains. “Wherever deer are, there are a lot more ticks than there would be without deer,” he says.

There is some agreement from across the pond. Dr. Lucy Gilbert is a Senior Research Fellow at the University of Glasgow with a focus on ecology, environmental change, and infectious disease ecology, along with evolution and diversity. Her research strongly suggests that the boom in deer distribution and abundance is a greater factor in the proliferation of ticks (though not necessarily Lyme disease) than climate change.

Lyme disease cases surged by 69 percent in 2022, according to the CDC. But even as data collections gets more efficient, there are still likely many cases missed. As STAT News reports, “There are a lot more cases of Lyme disease in the country than are ever reported to the CDC.”

The increase in disease incidence, Gilbert says, may be related to deer and climate change. Additional factors could be better awareness from the public and doctors identifying tick-related diseases, paired with an increase in outdoor recreation.

The simple answer is that activities that put you in tick habitat—long grass or forests with dense shrubs—will be higher risk than sports that don’t. Hiking and running in the woods increase the likelihood that you’ll encounter a tick. Even short grass, like you’d find on a baseball field or soccer pitch, can carry ticks, Krause says. Something on a hard court, like basketball, would be very low-risk.

The CDC recommends staying away from thick vegetation, high grass, and leaf litter and to “walk in the center of trails when hiking,” to avoid brushing up against grass or other plants where ticks might be hanging out.

Riding a bike on a trail might be lower-risk than running it, says Krause, because ticks will have greater difficulty reaching you from the grass, and cyclists are more likely to stay in the center of the trail. Walking may also be safer than trail running, as you’re more likely to avoid brushing any grasses in places with sharp turns, Krause says.

Dr. Kevin DuPrey, a sports medicine specialist, wrote a 2015 article about Lyme disease in athletes for Current Sports Medicine Reports, and he also has firsthand experience. When running cross-country at University of Delaware, Duprey contracted Lyme disease. Before he was diagnosed and treated, he’d experienced mid-race fatigue—to the point of wanting to lie down and nap during the middle of a competition.

Today, as a precaution, DuPrey tries to avoid overgrown trails especially from mid-May through August, when the transmission rate is highest for Lyme and other tick-borne diseases. He’ll check himself for ticks after running, or even mid-run if he’s in an overgrown area.

He recommended bug spray with DEET to repel ticks, but also offered a clothing tip: light-colored threads can make it easier to spot ticks on your body.

The CDC also recommends using EPA-registered insect repellents (like OFF! Active Insect Repellent I), wearing loose-fitting clothing, and treating your gear with permethrin, an insecticide that should not be applied directly to your skin. The organization even has chat bots to help you find effective repellents (they recommend something with DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol, or 2-undecanone) and assessing tick bites.

“In general, DEET, if used as prescribed, is safe,” Krause says. You wouldn’t want to apply it to a small child if they’re going to lick their skin, he says, but considers it safe overall when used as directed. If ingested, it can cause serious side-effects including seizures, according to the National Pesticide Information Center. But aside from a chance of skin irritation, it’s safe to apply topically. Permethrin, which is only suitable for application to gear and clothing, has more safety concerns, says Krause.

When you head back inside, Hinckley recommends you check your clothing and gear for ticks. Then, using a mirror, check your entire body, particularly under your arms, in and around ears, inside your belly button, the backs of your knees, your hair, between your legs, and around your waist. Then, take a shower as soon as possible.

Hinckley also encourages good tick hygiene for pets. Preventative products like topicals, chews, and collars can help, and she advises manual pet-downs for ticks after time outside. This isn’t just for your pets sake—ticks can take a pitstop on your four-legged roommate before making their way to you.

It’s understandable that you might freak out if you find a tick, especially if it’s attached. But if you find it early—within 36 to 48 hours—DuPrey say, the chance of Lyme disease transmission is actually very low.

If you’re uncertain how long it’s been since you were bitten, he advises seeking professional medical advice, especially if you were bit during the summer months, find a circular rash, or experience flu-like symptoms. If caught early, both Krause and Duprey says, Lyme and other tick-borne diseases can be treated with antibiotics.

As an expert who’s closely studied ticks and tick-borne diseases, Gilbert praises the media’s coverage in highlighting tick awareness and Lyme disease. But she says there is sometimes “too much scare-mongering and exaggerating the outcomes of Lyme disease.” While noting that some people progress to chronic Lyme disease, which can be debilitating, the vast majority of people who contract Lyme do not develop a long-term illness.

Gilbert has heard about certain tick-removal techniques like applying Vaseline, olive oil, or burning them off your skin, but her advice is simple: “This is not a good idea!” Instead, she recommends gently plucking the tick off of your skin by its mouth, using fine tweezers or tick tools (available at veterinary clinics, pharmacies, and online) which won’t squash the tick. If you do find a tick, take a picture before you dispose of it, so you can show it to a doctor in the event you need to visit one.

For disposal, the CDC recommends putting the bug in alcohol, a sealed bag, tape, or a soon-to-be-flushed toilet. The CDC also has resources that can help you decide what to do after a tick bite.

People with immunocompromising conditions are at greater risk for tick-borne infection, Krause says, and should exercise additional caution. As a historical example, he notes when Babesia (the parasite that causes Babesiosis) took over Nantucket, an editorial in the New England Journal of Medicine advised people who didn’t have a spleen avoid buying land on Nantucket. (The spleen, which helps fight infection, is crucial in warding off Babesiosis.)

The best path forward might be to channel an anti-Robert Frost mentality. If you’re going to choose a path to hike, run, or a bike, choose a well-worn one, and stay in the center of it. And I’m not sure if Frost wrote a poem about this, but check your body, take a shower, and throw all your clothes in the dryer when you get back inside.

Ethiopia’s Fotyеn Tesfay Haylu delivered one of the most remarkable women’s half-marathon performances ever seen on American soil on Sunday, powering to a commanding victory at the 2026 Buenos Aires Half Marathon in Argentina in 1:03:57.

Running with exceptional confidence and strength, Tesfay took control of the race and produced a superb solo performance to rewrite the event record. Her breathtaking run also carried historic significance, as she became the first woman to break the 64-minute barrier for the half marathon in the Americas, producing what is being celebrated as the fastest women’s half-marathon performance ever recorded on the continent.

The Ethiopian star was in a class of her own, crossing the finish line more than a minute clear of Turkey’s Nevin Can, who finished second in 1:05:06. Another Turkish athlete, Selin Can, completed the podium in third place with 1:05:11, as the leading trio all produced strong performances on the fast streets of Buenos Aires.

Kenya also featured prominently in the top positions, with Irene Jepchumba Kimais taking fourth in 1:06:04, followed by Sheila Chepkirui in fifth with 1:06:13. Magaret Akidor Ngathike finished sixth in 1:06:46, while fellow Kenyan Deborah Samum claimed seventh place in 1:08:32.

Brazil’s Nubia de Oliveira Silva was eighth in 1:11:13, while Argentina’s Sofia Luna and Dahyana Juarez rounded out the top 10 with times of 1:11:21 and 1:11:28, respectively.

Top 10 Women – 2026 Buenos Aires Half Marathon

1. Fotyеn Tesfay Haylu (Ethiopia) – 1:03:57

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

4. Irene Jepchumba Kimais (Kenya) – 1:06:04

5. Sheila Chepkirui (Kenya) – 1:06:13

6. Magaret Akidor Ngathike (Kenya) – 1:06:46

7. Deborah Samum (Kenya) – 1:08:32

8. Nubia de Oliveira Silva (Brazil) – 1:11:13

9. Sofia Luna (Argentina) – 1:11:21

10. Dahyana Juarez (Argentina) – 1:11:28

For Tesfay, it was far more than a race victory. Her 1:03:57 performance was a statement of extraordinary quality, combining speed, endurance and remarkable solo running to produce a landmark result in Buenos Aires. In a race that will be remembered for years to come, the Ethiopian did not simply win—she redefined what was thought possible for women’s half-marathon running in the Americas.

Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.

Kenya delivered another commanding display of distance-running excellence at the Antrim Coast Half Marathon, with Isaia Lasoi leading a memorable Kenyan clean sweep of the men's podium in a race packed with world-class performances.

Lasoi emerged victorious after a thrilling battle at the front, crossing the finish line in a superb 58:26 setting a new course record. His winning performance underlined his strength and speed over the half-marathon distance, but he was made to work all the way by fellow Kenyan Daniel Mateiko, who finished just three seconds behind in 58:29 after an electrifying duel for the title.

The contest between the two leaders produced one of the standout moments of the race, with both athletes pushing deep into elite territory as they fought for victory. In the end, Lasoi found just enough to secure the win, while Mateiko's narrow defeat highlighted the remarkable depth and quality of Kenya's leading distance runners.

Vincent Kipkorir completed the Kenyan sweep, taking third place in 1:00:38 to ensure that all three places on the podium belonged to Kenyan athletes. Samwel Chebolei added further Kenyan strength to the results, finishing fourth in 1:01:01, while Amos Langat was also among the leading finishers.

The international field featured several prominent names. Australia's Jimmy Whelan produced a strong run, while Ethiopia's Yismaw Dillu featured among the front group. American marathon star Galen Rupp also delivered a notable performance, clocking 1:01:29 in another competitive outing for the experienced distance runner. Former world-class track and road athlete Edward Cheserek was also among the top finishers.

Lasoi's 58:26 victory, however, was the defining performance of the day. Together with Mateiko and Kipkorir, he gave Kenya a perfect podium and another emphatic reminder of the country's extraordinary strength in elite road running.

The Antrim Coast Half Marathon once again provided a fast, competitive stage for some of the world's finest distance runners, but when the decisive moments arrived, it was Kenya that owned the podium.

One of the most iconic milestones in the history of ultramarathon running is drawing closer, with entries for the historic 100th edition of the Comrades Marathon set to open on Tuesday, 25 August 2026.

The Comrades Marathon Association has officially announced a detailed entry process for the 2027 race, which will unfold in three stages and give runners around the world the opportunity to secure their place in what promises to be one of the most significant editions ever held of The Ultimate Human Race.

The announcement followed the official launch of the 2027 Comrades Marathon on Wednesday, 19 August, when the centenary campaign, “The Greatest Story Ever Run,” was unveiled alongside a special logo created exclusively for the landmark 100th edition.

The launch also revealed several major highlights for the Centenary Race. The historic event will take place on Sunday, 13 June 2027, and will be a Down Run, with 28,000 places available. The entry process will include a ballot, while the race will offer a record R8.919 million in prize money. Organisers have also set an ambitious goal of raising R10 million for the Amabeadibeadi charities, adding an important charitable dimension to the centenary celebrations. One of the defining moments of the launch was the unveiling of the special Centenary mark, created to commemorate this extraordinary milestone in the history of the race.

The entry process begins on 25 August at 10:00 a.m. SAST, when entries open for Green Number runners, Yellow Number runners and Amabeadibeadi charity entrants.

The next phase follows on 2 September at 10:00 a.m. SAST, when entries open for Comrades Marathon Association members. This window will remain open for 72 hours or until the available entry allocation is filled, with places offered on a strictly first-come, first-served basis.

For general entrants, the process will move to a ballot system. General entries open on 9 September at 10:00 a.m. SAST, with runners able to enter the ballot until it closes on 22 September at 4:30 p.m. SAST. The ballot draw is then scheduled to take place on 23 September.

Several other crucial dates will shape the road to the historic race. The substitution period will run from 15 to 31 March 2027, while 3 May 2027 is the final deadline for runners to submit their qualifying performances, seeding information and other required entry details.

To qualify for the 2027 Comrades Marathon, runners must complete a 42.2km marathon in under five hours between 15 June 2026 and 3 May 2027.

The journey will finally culminate on Sunday, 13 June 2027, when thousands of runners are expected to line up for the historic 100th edition of the Comrades Marathon.

For more than a century, the Comrades Marathon has captured the imagination of runners and spectators with its extraordinary test of endurance, determination and human spirit. Its centenary edition will celebrate the generations of athletes who have faced its demanding roads, conquered its challenges and helped build one of the world's most respected endurance events.

For runners dreaming of becoming part of this historic occasion, the road to Comrades 2027 is now clearly marked. From the opening of entries in August 2026 to race day in June 2027, every deadline will matter.

The Greatest Story Ever Run is preparing for its most historic chapter yet.

American sprint standout Sam Blaskowski is taking steps toward an international future with Poland after uncovering a powerful connection to his family's ancestral homeland.

The 23-year-old sprinter, who has established himself as one of the fastest Americans of his generation with a personal best of 9.89 seconds in the 100 metres, has begun the process of obtaining Polish citizenship with the aim of eventually representing Poland in international competition.

Blaskowski's connection to the country traces back through his great-grandparents, Franciszek and Julian Błaszkowski, who emigrated from Poland to the United States in 1905. Their journey more than a century ago has now opened an unexpected new chapter for their descendant, whose athletic ambitions could soon carry the Błaszkowski name back onto the international stage under Polish colours.

The sprinter has already received support from the Polish Athletics Association as he works through the citizenship and eligibility process. Should his transfer of allegiance be completed, Blaskowski could become a significant addition to Poland's sprint programme.

His credentials certainly make the prospect an exciting one. In addition to his sub-10-second speed over 100 metres, Blaskowski owns a personal best of 19.93 seconds in the 200 metres, demonstrating the kind of versatility that could prove valuable both individually and in Poland's 4x100m relay squad.

For Blaskowski, however, the move is about more than simply changing national colours. It represents an opportunity to reconnect with his family's heritage while pursuing his ambitions at the highest level of the sport.

With his sights set on becoming part of Poland's international sprint team and competing for relay medals, Blaskowski's journey from discovering his Polish roots to potentially representing the country of his ancestors could become one of the most fascinating allegiance stories in world athletics.

A century after Franciszek and Julian Błaszkowski left Poland for America, their family's story may now be coming full circle—this time at full sprint.
