A Brief History of the Iditarod Trail Sled Dog Race

The Iditarod Trail Sled Dog Race has its origins in two important events in Alaska’s history: the 1925 serum run to Nome and the historical Iditarod Trail.

The 1925 Serum Run

In 1925, Nome was facing a deadly diphtheria epidemic. The nearest serum was in Anchorage, nearly 1000 miles away. With airports and roads unusable due to the harsh winter, the serum had to be transported by sled dog relay teams. Over 20 mushers and about 150 sled dogs participated in the emergency delivery in just 6 days, saving Nome from the epidemic. This lifesaving 1925 serum run is considered one of the greatest feats in Alaska’s history.

The Iditarod Trail

The Iditarod Trail was established during the Alaska gold rushes in the early 1900s as a mail and supply route from the coastal towns of Seward and Knik to the interior mining towns of Nome, Iditarod, and beyond. At its peak, around 20,000 sled dogs were working along the trail. The Iditarod Trail played a vital role in Alaska’s early history before becoming obsolete when roads, air transport, and snowmobiles replaced sled dog teams.

Founding of the Iditarod Race

In the 1960s, the use of sled dogs for transportation declined rapidly with the introduction of snowmobiles. Concerned about losing this part of Alaska’s history and culture, sled dog enthusiasts began organizing races along the historic Iditarod Trail in the mid-1960s.

In 1967, the first major race along the full Iditarod Trail route was held, taking participants 3 weeks to complete. Then in 1973, Joe Redington Sr. and others founded the first official Iditarod Trail Sled Dog Race to commemorate the 1925 serum run and to save the dying sled dog culture. That year, despite doubts that anyone could complete the 1000+ mile race, 22 mushers entered the race, and 15 finished.

Over the years, sled dog breeding and training have improved to the point where top teams now complete the race in just over a week. The Iditarod Trail Sled Dog Race has evolved into the premier sporting event in Alaska and the most famous sled dog race in the world.

The Race Route, Distance, Duration, and Weather

The Iditarod Trail Sled Dog Race route travels through some of Alaska’s most remote and rugged wilderness, challenging both mushers and their sled dogs.

The Route

The northern and southern routes alternate each year, both starting in Anchorage and ending in Nome:

  • The Northern Route goes through checkpoints like the ghost town of Iditarod, the Yukon River, Kaltag, and Unalakleet. 
  • The Southern Route passes through coastal towns like Seward and winds through the Alaska Range with checkpoints at Nikolai and McGrath.

Each route has its own distinct terrain and challenges from mountains to tundra to the frozen Norton Sound. Mushers prepare strategically depending on that year’s route.


The official distance is 1,112 miles for the northern route and 1,131 miles for the southern route. However, the race is commonly said to be 1,049 miles, representing Alaska as the 49th state.


Top mushers and teams complete the Iditarod Trail in 8-9 days. The record fastest winning time was 8 days, 3 hours, 40 minutes, and 13 seconds set by Mitch Seavey in 2017. However, heavy snow or extreme weather can slow teams and extend finishing times to 10-15 days for some mid-pack mushers.

Weather and Terrain

Frigid temperatures and brutal weather are expected along the Iditarod Trail which crosses remote Arctic and sub-Arctic terrain. Each year racers battle:

  • Temperatures far below zero.
  • High winds cause wind chill down to -100°F [-73°C].
  • Blinding blizzards with heavy, blowing snow.
  • Treacherous ice on the Norton Sound and river crossings.
  • Challenging climbs and descents over mountain ranges.

The grueling conditions test the endurance and survival skills of both the mushers and their sled dogs. It’s no wonder the Iditarod is called “the last great race on Earth.”

Dog Welfare Controversies and Critics

The Iditarod Trail Sled Dog Race has long faced criticism from animal rights activists claiming the race amounts to dog abuse. Several dog deaths and injuries over the years have fueled the controversy.

Dog Injuries and Fatalities

The extreme conditions and long distances pose risks to the dogs’ health and safety. There have been dog deaths from exposure, drowning, crashes, moose attacks, and more. Other dogs have received lacerations from broken sleds, injured limbs, or developed health issues like pneumonia.

Activists argue that forced racing leads directly to injuries and deaths that could be prevented by not holding the race at all. However, race supporters contend that the dogs are built for and love racing and that fatalities are rare considering over 1,000 dogs participate each year.

Mushers Disciplined for Dog Abuse

There have been some cases of mushers abusing or neglecting dogs, either during the race itself or in their kennels. This includes withholding food, tethering dogs so they can’t escape attacks, performance-enhancing drugs, and inhumane culling.

Race organizers point to policies enacted to increase scrutiny of mushers, monitor dog care, perform veterinary checks, and penalize those caught breaking animal welfare rules. But critics say the race culture promotes winning and profit over ethics.

Loss of Sponsors and Support

In the wake of dog deaths and injuries, some sponsors like ExxonMobil, Alaska Airlines, and Jack Daniels have ended their Iditarod sponsorships after pressure from activists like PETA. While some devote fans remain, critics have impacted corporate and public support of the race.

Race organizers are attempting to improve dog safety and care to regain public trust. But debates around balancing racing tradition and sled dog welfare continue to swirl.

Top Mushers to Watch

The Iditarod often pits grizzled veterans against rising rookie stars. Here are some of the top mushers to watch in this year’s race:

Veteran Mushers

Mitch Seavey – With 3 Iditarod wins, Mitch knows how to handle rough conditions and avoid mistakes over the 1000+ mile course. Age may slow him down, but never count this strategic racer out.

Dallas Seavey – Having won 4 times, Dallas has the most Iditarod wins of any musher. However, he’s sat out a few years due to disagreements over race rules. This could be Dallas’ comeback year.

Jessie Royer – A fan favorite for her tenacity, Jessie has racked up 8 top 10 finishes without a win. 2023 could finally be her year to claim victory.

Rookie Mushers

Ryan Redington – Part of the Redington Iditarod dynasty, Ryan has 15 Top 20 finishes under his belt already. He’s poised for a breakout performance.

Anna Berington – This up-and-comer has trained under four-time champ Dallas Seavey. She could pull off a surprise rookie win like Pete Kaiser did in 2019.

Thomas Waerner – The 2019 Iditarod champion from Norway is racing again this year. Can he repeat his commanding win on foreign soil?

With so many compelling storylines around past champions and rising stars, the winner is nearly impossible to predict!

Top Sled Dog Breeds for Racing

The canine athletes of the Iditarod are specially bred and trained racing sled dogs. Let’s look at the key breeds that make up these powerhouse teams:

Alaskan Husky

Alaskan Husky scaled

This mixed breed has been specially developed for endurance, speed, and toughness over long distances. They have unparalleled stamina and a drive to run even in the worst conditions.

Siberian Husky


Known for athleticism and agility, this breed adds speed and versatility. Their resilience in cold weather makes them well-suited to frigid and harsh conditions.

Alaskan Malamute

Adding brute strength, this freight-hauling breed provides pulling power to help navigate hills, snow, and other tough terrain. Their huge paws act like snowshoes.

Introducing pointer genes gives these hybrids sprint speed and enthusiasm for running. They provide a crucial burst of energy at the race start and during hills.

It takes a strategic mix of breeds in the team for each musher’s unique racing strategy over 1000 miles of changing terrain and conditions. The dogs’ performance truly makes or breaks the race.

Training and Preparing Sled Dogs for Racing

Top sled dog teams don’t just happen. It takes years of strategic breeding, training, and conditioning to build agile, energetic, and driven racing canines able to safely cover 1000+ miles at 10 mph or more.

Breeding Lines

Dedicated mushers carefully select breeding pairs that balance traits like endurance, speed, tough paws, appetite, and a high drive to run. This produces specialized hybrids like Alaskan Huskies optimized genetically over generations for racing.

Puppy Training

Training starts early by introducing puppies to sights, sounds, and equipment like harnesses to get them comfortable with the race environment. They progress to running paired up, then small teams, and finally full race teams of 12-16 over one to two years.

Building Endurance

Being able to run 125+ miles a day takes years to build up. Slowly increasing distances condition dog teams for the long haul. Veteran teams may log over 10,000 training miles in a year.

Optimizing Nutrition

The right high protein/fat diet fuels sled dogs without weighing them down. During the race, they burn over 10,000 calories per day. Veterinarians monitor dogs at each checkpoint to ensure adequate hydration, nutrition, and rest.

Preventing Injury

Massages, booties, chiropractic care, and rest days prevent and manage injuries from long distances. Mushers continually monitor dogs for signs of soreness, fatigue, and foot injuries. A single wrist or shoulder sprain can scratch a top contender.

It’s a year-round commitment for serious mushers and their dogs leading up to and beyond the big race. When race day arrives, victory comes down to preparation meeting opportunity.

What It’s Like To Run the Iditarod As a Musher

Steering a sled pulled by a pack of tireless dogs through the Alaskan wilderness sounds romantic. But piloting a team through blizzards and subzero nights over a thousand miles is a true test of human limits. Let’s look at the musher’s experiences behind the scenes.

Training Body and Mind

Preparing to mush for days on little sleep in brutal conditions requires training one’s body and mind. Mushers build toughness through cold exposure, strength training, wilderness survival skills, and mental stamina to overcome fatigue and stay alert. Managing stress is just as important as physical fitness.

Strategic Dog Handling

The race is won and lost on dog management. Mushers must know each dog’s abilities and signals. Vet checks, planned rests, snacking, massage breaks, paw care, hydration, pacing, and personality management are all key. Mushers keep dogs happy while covering 50-100 miles per day.

Wilderness Navigation

Mushers must expertly navigate treacherous, changing trail conditions often at night in whiteout blizzards. Missing a turn or hitting overflow ice instead of the true trail could cost the race. Some rely on memory and landmarks while others use GPS.

No Sleep Till Nome

Cat-napping in 2-4 hour chunks between runs is the norm. But with howling winds, cold, and the motion of the sled, quality sleep is elusive. Hallucinations are common by the last few days of sleep deprivation. Staying alert matters.

Eating On The Run

Quick hot meals at checkpoints refuel mushers. But crunch time means eating strips of beaver meat or salmon while mushing. Dehydration, hunger, and gastrointestinal issues are competitors too. Planning food and hydration is crucial.

Experienced mushers make the extreme look easy. But conquering the “last great race” requires skill, strategy, endurance, and an incredible human-canine bond.

Spotlight On Memorable Iditarod Racers

The Iditarod has seen colorful characters gain fame over the event’s 50-year history. Let’s look back on a few of the most legendary and memorable mushers:

Dick Mackey

In 1978, Dick Mackey and his dogs blitzed through a raging blizzard to become the first musher to reach Nome in under 15 days. This comeback win sealed his status as one of the toughest mushers ever.

Susan Butcher

Susan Butcher dominated through the 1980s, winning 4 out of 6 years. She pioneered dog care and training methods adopted by mushers today. Her team once hauled her sled 525 miles back after she broke her ankle mid-race to save her life.

Martin Buser

Martin Buser’s visionary approach changed mushing from basic survival to science and strategy. His meticulous preparation and innovations like replacing wood stoves with synthetic coats helped him win 4 times.

Lance Mackey

Lance Mackey’s back-to-back-to-back wins from 2007-2010 made him the race’s second biggest star after Susan Butcher. His battle against cancer inspires fans.

DeeDee Jonrowe

A fan favorite for 23 consecutive Iditarods, DeeDee exemplifies courage and tenacity. She raced just 3 weeks after breast cancer treatment and continued after losing her 16-year-old daughter to a drunk driver.

The unique personalities are what capture attention and create legends as big as the race itself.

Frequently Asked Questions About The Iditarod

If you’re new to the world of mushing, chances are you have plenty of questions about the mechanics of the race. Here are answers to some frequently asked questions:

Dogs curl up in straw inside the sled bag. Mushers use heat lamps, massages, and coats for protection. The dogs’ double coats and constant motion keep their cores warm.

Sled dogs consume around 10,000 calories per day in meat/fat-based kibble, raw snacks, and food dropped at checkpoints. Their high metabolism keeps their energy levels up.

The entry fee is $4,000 per musher. But total costs with gear, dog care, transportation, and supplies can exceed $20,000 – $30,000. Top competitors invest over $100,000 per year in training.

Mushers only get 2-4 hours of intermittent sleep per 24 hours during the 8-15 day journey. Catnaps happen on the trail, at checkpoints, or resting with dogs.

Sick, injured, pregnant or fatigued dogs get “dropped” at checkpoints and flown to Anchorage. Mushers cannot replace dropped dogs, so losing several can doom their chances.

Veterinarians at checkpoints examine each dog, looking for injuries, dehydration, or signs of overexertion. GPS tracking lets race officials check a team’s pace.

Yes, but rookies must prove themselves ready at shorter qualifying races to gain entry. All mushers must pass veterinary, wilderness survival and dog care pre-checks too.

The high cost and ultra-intense training deter many would-be racers. Top mushers compete more for the love of their dogs and for achieving the extraordinary.
