Month: March 2023

Remember childhood summers when you climbed monkey bars, swung from ropes, and jumped over streams? Rain just added to the fun, leaving you soaked and muddy.

You can relive those adventures by signing up for a mud run. These outdoor team events focus on navigating through military-inspired obstacle courses and getting good and dirty in the process.

Tough Mudder and Spartan races are the most well-known mud races. But similar mud runs are available in most states. Some offer shorter distances and levels of difficulty. Others are designed just for women, kids, or families.

How do mud runs work?

Usually these events follow the same basic concept: participants traverse a course that covers anywhere from three to 10 miles (or longer), and tackle 10 to 25 obstacles.

While some mud races can be done solo, most are designed as team-oriented events. Teams are often coed and consist of five to 10 people. There is no time limit, but depending on the distance and number of obstacles, most teams complete the course in anywhere from less than an hour to three-plus hours.

The obstacles are challenging enough that most people need help — physically and emotionally — to navigate over, under, and across them. This is where a “we’re-all-in-this-together” comradery comes into play.

What sort of obstacles are featured in mud runs?

Common obstacles include

• climbing over spider web-like cargo nets
• scaling walls of various heights
• swinging from ropes with handles
• keeping your balance while walking across beams or logs
• carrying logs or sandbags
• slithering under barbed wire.

And then there’s all the mud. Be prepared to trudge through sticky mud pits, crawl through muddy tunnels, and shoot down mud-slick slides.

What are the health benefits of a mud run?

According to Dr. Aaron Baggish, founder of the Cardiovascular Performance Center at Harvard-affiliated Massachusetts General Hospital, the benefits of these events come from how they are constructed.

“Obstacle racing combines large-muscle, whole-body resistance exercises superimposed on a long-distance endurance race,” he says. “They are a snapshot of all-around conditioning, as you need strength, stamina, and mobility.”

Besides the physical benefits, mud races offer psychological challenges, and the emotional rewards, of conquering tasks that require planning, coordination, and strategy.

How can you prepare for a mud run?

Mud races require strenuous exercise, so discuss your safety and capabilities with your doctor before signing up for an event. While almost anyone of any age can participate in these events, they require a certain level of conditioning to complete and to reduce the risk of experiencing injury.

“Training for obstacle races incorporates many aspects of fitness and performance,” says Dr. Baggish. “So it’s best to prepare with a coach or trainer who understands the fundamental skills needed to complete these races.”

Whether or not you work with a trainer, you’ll want to focus on:

• Aerobic fitness. While you won’t consistently run as you do in a traditional road race, such as a 5K or a half marathon, you do have to hustle from obstacle to obstacle. “Optimal training for such obstacle races involves a combination of steady-state aerobic base training like jogging or cycling, coupled with interval work that simulates the start-and-stop nature of competition,” says Dr. Baggish.
• Grip strength. You will have to grab, hold, and pull yourself against gravity. Exercises that can help include pull-ups and farmer carries (where you hold dumbbells or kettlebells in each hand while you walk back and forth). Good form is essential during these exercises to help you avoid injury. Remember to start low when working with weights and go slow.
• Plyometrics. Many obstacles require explosive jumps and quick movements. Exercises like box jumps, burpees, and jump squats can help replicate these moves.

How to stay safe in the mud

While being physically prepared can help reduce the risk of injury, you should take other precautions to stay safe. For instance:

• Choose your race depending on level of fitness. Be sure you know what you’re getting into before you go.
• Wear lightweight, moisture-wicking clothing. Avoid cotton, which gets heavy with mud and sweat.
• Wear a headband, protective eyewear, or visor to keep mud out of the eyes.
• Wear long shorts or pants that cover your knees to prevent scraping, or opt for knee pads.
• Consider gloves to protect your hands and provide extra grip.
• Cover your feet with petroleum jelly or an anti-chafing cream before putting on socks to protect wet feet from chafing and blisters.
• Tie shoelaces tightly (but not so tight that they cut off circulation). Mud creates suction and you can quickly lose a shoe.
• Pace yourself. Walk or take a break when needed.

Where can you find a mud run?

It depends on the level of challenge that you seek. Are you ready for a Tough Mudder or Spartan race? Looking for a family first mud run, or a Muddy Princess or Muddy Kids event?

Here’s a new fact about spring, summer, fall, and sometimes even winter, now that climate change has blurred seasonal boundaries: sizzling heat may be on the way, or currently blanketing your community.

High temperatures stress the body, leading to thousands of heat-related illnesses and deaths every year in the US. Creating a personal heat plan can help you stay safe when the heat index soars.

Caleb Dresser, MD, MPH, is the health care solutions lead for C-CHANGE, the Center for Climate Health and the Global Environment at the Harvard T.H. Chan School of Public Health, and an emergency medicine doctor at Harvard-affiliated Beth Israel Deaconess Medical Center. Below we interview him about who, how, and why heat harms. Then we’ll help you create your personal heat safety plan.

Interview edited for clarity

Who is especially vulnerable during hot weather?

High temperatures can affect anyone. But some people — children, outdoor workers, people who are pregnant or have health problems or disabilities, and older people — are more likely to experience harm when temperatures rise. For example:

• Young children, especially babies, have less physical capacity to deal with very high temperatures.
• People working outdoors may not have access to shade and could be performing physically intensive labor. They need adequate hydration, adequate breaks, and access to a cool space during break time, as OSHA guidelines spell out.
• People with chronic medical conditions, such as kidney disease or heart disease, may have difficulty adapting physiologically to hot weather, or may be more susceptible to its health impacts.
• And some people living with disabilities or certain neurological conditions may have difficulty with thermoregulation — that is, controlling the temperature of their bodies — or may not be able to take actions that keep them safe, such as taking off layers or moving to a cool area.

Which weather patterns create dangerous levels of heat?

Dangerous heat is the result of both high temperatures and high humidity, which interfere with our ability to cool off by sweating. In dry areas, extremely hot temperatures can be dangerous on their own.

Danger zones vary across the United States and around the world. But hospital use and deaths rise once we get above threshold temperatures. The threshold varies in different places depending on whether bodies, cultures, and architecture are adapted to heat.

For example, here in New England, where some people (particularly those of limited means) may not have access to air conditioning, we see increases in healthcare use and deaths at a lower temperature than in the American South, where people and organizations may be more used to dealing with hot weather.

When does hot weather become dangerous to our health?

Risk goes up the longer hot weather sticks around.

One hot day can put some people at risk. A stretch of several hot days in a row during a heat wave is particularly dangerous because it can overwhelm people’s ability to adapt. Eventually people run out of physiological reserves, leading to greater health harms and greater need for medical care.

Surprisingly, spring and early summer are particularly dangerous times because people and organizations aren’t as prepared for hot weather.

How to create your personal heat safety plan

Five key points to help you create a personal heat plan are below. Americares offers further information through heat tip sheets developed with the Harvard C-CHANGE team that are tailored to people in different health circumstances.

Planning is important because intense heat is occurring more often: a Climate Central analysis found 21 additional risky heat days, on average, for 232 out of 249 locations between 1970 and 2022.

• Stay ahead of hot weather. Check apps, websites, TV, or radio for updates on weather today and in coming days. If local weather alerts are available by phone or text, sign up.
• Have a cooling plan. When temperatures soar, you need to spend as much time as possible in cool spaces. Plan options if your home is likely to be too hot and unsafe to stay in. You may be able to stay with a neighbor or family member who has air conditioning until a heat wave passes. Many cities and towns have neighborhood splash pads for children, and open cooling centers or air-conditioned libraries, public buildings, or community centers to everyone — sometimes even overnight. Spending time in air-conditioned businesses or malls, or in a shady green space like a park, may help too.
• Sip plenty of fluids. Water is the best choice. Skip sugary drinks and avoid caffeine or alcohol.
• Use fans correctly. Fans help if surrounding air is relatively cool. If air temperatures are very high, it’s important to dampen your clothes or skin to help keep your body from overheating, and move to a cooler location, if possible.
• Know your personal risks and the signs of heat-related illness. If you have health problems or disabilities, or take certain medicines such as diuretics, talk to your doctor about the best ways for you to cope with heat. It’s also essential to know the signs of heat-related illnesses, which range from heat rash and sunburn to heat cramps, heat exhaustion, and heat stroke. This chart from the Centers for Disease Control and Prevention describes the signs to look for and what you can do, particularly when heat becomes an emergency.
