Triathlon
Getting Started with Triathlon
Three sports, one race. Swim, bike, run — in that order, back to back, with two transitions in between that become their own kind of skill. Triathlons are one of the more dynamic challenges in endurance sports.
You don't have to be an Ironman to love this sport. The sprint distance is short enough to finish on your first attempt, and varied enough that race day never gets monotonous.
Open water, open roads, and competition with yourself. The swim start is exciting and chaotic — cold water, people everywhere, but it finds a rhythm fast. The bike course is usually quiet. The run brings people back — spectators, cowbells, and the finish line.
Runners looking for a new challenge, swimmers wanting a finish line, or anyone drawn to training across three disciplines. If you already swim, bike, or run with any regularity, you're likely more prepared than you think.
A pair of goggles, a bike, a helmet, and shoes you're comfortable running in are the baseline. Most bikes work fine for a first sprint. If you're not a comfortable swimmer, pool access and a few lessons before race day will go a long way. A wetsuit helps in cold open water.
Recommended starting point
The shortest official distance — 750m swim, 20K bike, 5K run. Three disciplines means three movements to train for, and race day never gets monotonous. You're always moving, pushing yourself, without repetitive overload on any one movement.
Founder's take
"I did my first sprint tri after running a few half marathons. The swim was uncharted waters for me, so I got lessons, put in pool time, and started doing mock sprint tris. The variety of three sports in one race was a blast and unlike anything I'd done before."

Training Tips
Know how to do all 3 events.
Most triathletes have one discipline they avoid. Don't. Identify your worst discipline in week one and give it extra time early.
Train the transitions
You will need to transition from swim to bike and bike to run. Doing workouts consecutively — bike immediately after a swim, or run immediately after a bike — prepares you for running each event under fatigue.

Frequently Asked Questions (FAQs)
- What is a triathlon?
- A triathlon is a multi-sport endurance race made up of a swim, a bike, and a run — completed back to back in that order, with timed transitions between each discipline.
- What is the shortest triathlon distance?
- The sprint distance is the shortest standard triathlon format: a 750m swim, a 20K bike, and a 5K run. It is the most common starting point for first-time triathletes.
- How long does it take to train for a sprint triathlon?
- First-time sprint triathletes can train for 8–16 weeks and run a race, but preparedness obviously depends on starting fitness level in each of the three disciplines. Athletes who already swim, bike, or run regularly often are on the lower end of the range, and athletes that are just starting out will need more time.
- What gear do I need for my first triathlon?
- At minimum: goggles, a bike that fits you, a helmet, and shoes you're comfortable running in. Most regular bikes are fine for a first race, and triathletes often upgrade their bike over time as they get more involved in the sport. A wetsuit is helpful in cold open water, but is not required for every race.
- What is the difference between a sprint and Olympic triathlon?
- Both formats follow the same swim-bike-run order. A sprint triathlon is 750m / 20K / 5K. An Olympic-distance triathlon is roughly double: 1.5km swim, 40K bike, and 10K run.
