What is a Triathlon?

It’s madness.

Now seriously, a triathlon consists of three disciplines performed sequentially:

  1. Swimming

  2. Cycling

  3. Running

It’s basically the athletic version of juggling while on fire—only wetter and with tighter clothes. Triathlons come in various formats to suit different skill levels and goals. The most common race formats include:

  • Sprint: 750m swim, 20km bike, 5km run

  • Olympic: 1.5km swim, 40km bike, 10km run

  • Half Ironman (70.3): 1.9km swim, 90km bike, 21.1km run

  • Ironman: 3.8km swim, 180km bike, 42.2km run

Why should you try Triathlon?

Why be bad in one sport if you can be bad in three?

  • Variety in Training: Combines three disciplines, so you’re less likely to get bored. Can’t face another run? Let’s get cycling! Or take a dip in the pool and pretend you’re a dolphin.

  • Community: You’ll meet amazing people who understand the struggle of trying to run with jiggly legs after cycling 20km.

  • Personal Growth: Prove to yourself (and your couch-loving friends) that you’re capable of training for months at a time to accomplish incredible things.

Essential Gear for Your First Triathlon

Triathlon isn’t cheap but you don’t need to sell your soul (or your car) to get started. Here’s a list of essential gear:

Swimming

  • Swimsuit or tri-suit (yes, you’ll look like a superhero—embrace it)

  • Goggles (because chlorine isn’t a good look for your eyes)

  • Swim cap (often provided at races, so no excuses!)

  • Wetsuit (optional for colder water but mandatory if you’re a fan of floating)

Cycling

  • Bike (heavily dependent on the type of triathlon but usually road bike or TT bike)

  • Helmet (mandatory and lifesaving—literally)

  • Cycling shorts or tri-suit (trust me, your backside will thank you)

  • Water bottle and cage (hydration = happiness—we will get to this later)

Running

  • Comfortable running shoes (skip the ones with holes from 2012)

  • Socks (or don’t—some triathletes live on the edge)

  • Hat or glasses for sun protection (and to hide the helmet hair)

Additional Items

  • Race belt for your bib number (or safety pins if you’re old school)

  • Nutrition (gels, bars, or whatever keeps you from raiding the snack table mid-race)

Training Basics

Structure Your Training

A balanced training plan includes all three disciplines and allows time for rest and recovery. Here’s a sample 4-week plan for beginners training for a sprint triathlon:

Week 1

  • Monday: Rest (yes, this is important— it’s when your body recovers to come back stronger)

  • Tuesday: 30-min swim, 45-min bike

  • Wednesday: 30-min run

  • Thursday: Rest or mobility training (bonus points if you can touch your toes)

  • Friday: 25-min swim, 30-min bike

  • Saturday: 30-min run

  • Sunday: 45-min bike

Gradually increase the duration and intensity each week.

Key Training Tips

  1. Practice Transitions: Set up a mini transition area in your backyard and practice moving quickly from swim to bike and bike to run. It’s like a triathlete’s version of musical chairs. Get familiar with jumping to the bike if you’re brave enough, switching shoes, put and take off your helmet in 0.02 seconds.

  2. Open Water Practice: If your race includes open water swimming, practice in a lake or ocean. Pro tip: don’t panic if you see seaweed—it’s not trying to grab you. If you’re not comfortable enough with open water swimming, get a buoy—it’s a lifesaver and allows you to rest.

  3. Brick Workouts: Combine bike and run training in a single session to simulate race conditions. Yes, your legs will feel like bricks. No, it’s not just you.

Race Day Preparation

The Week Before (taper week for the connoisseur)

  • Check your gear and make sure everything is in working order (tighten those bike screws!).

  • Practice packing your transition bag—forgetting your shoes is a rookie mistake you don’t want to make.

  • Hydrate well and avoid overtraining—save your energy for race day.

Race Morning

  • Arrive early to set up your transition area. Usually your spot is marked with your name or race number. Check the surroundings to have a visual cue for where your spot is—this will be handy with the post-swim dizziness.

  • Walk through the transition zone to familiarize yourself with entry and exit points (and avoid running in circles later).

  • Warm up with light stretching and short swims or jogs. Remember, this is just the appetizer.

During the Race

  • Stay calm and pace yourself, especially in the swim (no one wins a triathlon in the first 50 meters, but you can definitely lose it).

  • Follow race rules and be mindful of other athletes (yes, even the one who splashes too much).

  • Smile and enjoy the experience—you’ve earned it! Plus, race photos are better with a grin.

Conclusion

Starting your triathlon journey is an exciting adventure filled with challenges, laughs, and definitely a few blisters. By understanding the basics, investing in essential gear, and committing to a consistent training plan, you’ll be well on your way to crossing the finish line. Remember, every athlete starts as a beginner. The most important step is the first one—signing up. Now, go crush it and remember: it’s called a tri-athlon, not a "try once and quit"-athlon!

Now go train.
