Triathlon training plans, built for your goal

Triathlon's real challenge is rarely any single discipline — it's balancing swim, bike and run within a realistic weekly schedule and surviving the run off a hard bike leg. SportBlox builds your triathlon training plan around your distance goal, schedule and event date, and works with your Strava data.

Who it's for

First sprint triathlon

A balanced introduction to all three disciplines plus basic transition practice.

70.3 (half-ironman) PB

Structured bike and run threshold work layered onto a rising long-session distance.

Full-distance finish

High-volume, periodised training building the endurance a full-distance race demands.

A week of triathlon training

How SportBlox personalises it

Your goal & event date

Sessions build toward the specific goal and date you set, with a taper if you're racing or competing.

Your skill level

Volume and intensity scale to where you actually are, from Inexperienced to Professional.

Your stated weaknesses

Tell SportBlox about things like “bike-to-run transition legs (brick fatigue)”, “swim pacing in open water”, “balancing three disciplines around limited time” and the plan weights sessions toward fixing them.

Your schedule

The plan fits the days and time you say you have — not an idealised training week.

Works with Strava

Connect Strava and your logged sessions feed back into pacing and progression.

Coaching a triathlon team?

SportBlox builds your team's training plan around the squad as a whole — its goals, weaknesses and upcoming events — and you review and refine every session before your athletes see it.

For coaches

Triathlon training plan FAQ

Does this work with Strava across swim, bike and run?

Yes — connect Strava and all three disciplines feed back into pacing and progression.

How do I train three sports on limited hours?

Tell SportBlox exactly how many hours you have each week and it prioritises the sessions with the biggest impact rather than trying to fit in everything.

Is this suitable for a first sprint triathlon?

Yes, set your goal distance and skill level and the plan introduces brick sessions gradually.

Can it work around my existing swim squad or cycling club?

Yes, tell it your existing sessions and the plan builds the rest of your training around them.

Does it taper before race day?

Yes, add your race as an event and the final week reduces volume across all three disciplines while keeping race-pace sharpness.
