How to train for a triathlon

A triathlon is an endurance race that combines swimming, cycling, and running - always in that order. Distances vary, from shorter sprint events all the way up to the Ironman:

Ironman: 3.8 km swim, 180 km bike, 42.2 km run (226 km total)
Half Ironman (70.3): 1.9 km swim, 90 km bike, 21.1 km run (113 km total)
Olympic: 1.5 km swim, 40 km bike, 10 km run (51.5 km total)
Sprint: 0.75 km swim, 20 km bike, 5 km run (25.75 km total)

Triathlon training is demanding - it pushes your endurance, resilience, and mental grit across three sports - but the variety also keeps it fresh and rewarding. Once you complete your first race, it’s easy to see why so many athletes come back for more.

Training well means balancing all three disciplines in a way that’s sustainable. That might look like following the 80/20 principle (80% of training easy, 20% harder efforts), making your sessions social by joining a club, and committing to a routine that fits your lifestyle. The real key is structure: a plan that manages your swim, bike, and run while keeping you consistent and accountable.

That’s where Runna comes in. We’ll create a personalized triathlon program built around your fitness, distance, and goals - and we’ll guide you through every step, from your first session to the finish line.

Hi there! Juggling three sports can feel daunting at first, but you don’t have to do it alone. We’ll give you the structure and support to stay on track, build your fitness step by step, and show up on race day knowing you’re ready.
