Craziest Marathon to Crush 2025

Every New Year brings that same question: What’s your resolution? While many go for “I’ll finally eat more salads” or “Let’s tackle the garage,” some brave souls decide to lace up their trainers and tackle something a little… crazier: marathons. However, these marathons are not your typical 26.2 miles through city streets; they are wild, unique, and truly extraordinary.

Let’s break down the top marathons everyone’s buzzing about, what makes them so mental, how to prepare, and how to sign up. Whether you’re after safari animals or sand dunes, we’ve got you covered!

1. The Big Five Marathon

Location: South Africa
Vibe: Safari meets sweat!

This is the marathon for adventurers. Imagine running through the Entabeni Game Reserve, a sprawling African savanna home to zebras, giraffes, rhinos, and even lions! No fences, no concrete, just you, nature, and a heart-pounding mix of adrenaline and endurance.

Why it’s crazy:

• Wildlife encounters. You’re running in an open reserve, with rangers on standby to ensure your safety.
• Tough terrain. Forget flat roads—expect dirt paths, rocky climbs, and uneven ground.
• No cheering crowds. It’s just you, the wilderness, and maybe a curious giraffe.

How it works:
The Big Five Marathon isn’t just a race; it’s a week-long adventure. Most participants book through official tour operators, which include luxury accommodation, guided safaris, and post-race celebrations.

What you’ll need:

• Trail running shoes (trust me, your feet will thank you).
• A solid training plan for hills and uneven terrain.
• A sense of adventure—and maybe a camera for the views!

How to apply:
Visit the official Big Five Marathon website to book your spot. Packages fill up fast, so don’t delay.

2. The Marathon des Sables

Location: Morocco
Vibe: Survival of the fittest!

Dubbed the “toughest footrace on Earth,” this ultramarathon spans six gruelling days and 250 kilometres across the Sahara Desert. Temperatures soar past 40°C, and runners carry all their food, gear, and survival essentials on their backs.

Why it’s crazy:

• The heat. Running in temperatures comparable to an oven is a serious challenge. Hydration becomes your lifeline.
• Self-sufficiency. You’re carrying your own supplies—think food, sleeping bag, and medical kit. Every gram counts.
• Mental endurance. Six days in the desert can break even the toughest competitors. You’ll battle sandstorms, isolation, and fatigue.

How it works:
Each day has a different stage, ranging from 20 to 80 kilometres. Water is rationed at checkpoints, and medical tents are set up to treat blisters, dehydration, and heat exhaustion.

What you’ll need:

• A lightweight backpack to carry essentials.
• High-calorie, compact food (freeze-dried meals are a favourite).
• Stamina, grit, and mental toughness.

How to apply:
Registration opens on the Marathon des Sables website. The entry fee includes logistics, water rations, and support—but it’s pricey, so start saving now.

3. The Walt Disney World Marathon

Location: Florida, USA
Vibe: Magical miles of nostalgia

If the thought of running 26.2 miles seems intimidating, why not take on the challenge in the most joyful place on Earth? This marathon takes you through all four Disney parks, with fireworks, character meet-and-greets, and a festive atmosphere. It’s like being in a Disney movie, but with more sweat.

Why it’s crazy:

• Distractions galore. It’s hard to focus when Mickey and Goofy are cheering you on.
• Costumes! Many runners dress as their favourite Disney characters.
• Family-friendly fun. There’s a whole weekend of events, including kids’ races and a half-marathon.

How it works:
The main marathon is part of Disney’s “Run Disney” weekend. You’ll start early (we’re talking 5:30 a.m.) and run through iconic locations like Cinderella’s castle and Epcot’s World Showcase.

What you’ll need:

• Comfortable, themed running gear (bonus points for creativity).
• Patience—this event is popular, so expect crowds.
• A love for Disney magic!

How to apply:
Spots sell out fast! Register early at Run Disney. Pro tip: Check out their “Dopey Challenge” if you’re feeling ambitious—it’s a combination of a 5K, 10K, half-marathon, and marathon over four days.

4. The Great Wall Marathon

Location: China
Vibe: Historic endurance challenge

One of the most iconic marathons in the world, this race takes you along the Great Wall of China. With over 5,000 steps to climb, it’s less of a run and more of a glorified stair workout.

Why it’s crazy:

• The stairs. Your legs will hate you, but your Instagram feed will love you.
• Remote location. This isn’t your typical city marathon; you’ll need to travel far and wide to get there.
• Cultural immersion. The course winds through villages and offers stunning views of the countryside.

How it works:
The race has multiple distance options (including a half-marathon and fun run), so you don’t have to commit to the full 42 kilometres. Expect steep climbs, narrow pathways, and breathtaking scenery.

What you’ll need:

• Strong quads (start training with stairs ASAP).
• A solid pair of running shoes with good grip.
• A sense of humour for when your legs start shaking.

How to apply:
Visit the Great Wall Marathon website to register. They offer packages that include race entry, accommodation, and sightseeing tours.

5. The Colour Run

Location: Worldwide
Vibe: Fun, fabulous, and messy!

The Colour Run is an ideal choice for individuals seeking a light-hearted experience. It’s a 5K event where you get doused in colourful powder at every kilometre, turning you into a walking rainbow by the finish line.

Why it’s crazy:

• No pressure. This is all about fun, not speed.
• The mess. You’ll need a good shower (and a laundry session) after.
• Post-race party. Most events end with music, dancing, and even more colour.

How it works:
Arrive, engage in physical activity, and enjoy an unforgettable experience! The powder is made from cornflour, so it’s safe for all ages.

What you’ll need:

• A white shirt to show off those colours.
• Sunglasses to keep the powder out of your eyes.
• A smile—it’s impossible not to have fun!

How to apply:
