Triathlon Training & Race Center

Turn swim, bike, run and transitions into one race: predict finish time, split target paces, plan fueling, train bricks and prep your transition bag.

The four standard distances

Sprint

🏊 750m · 🚴 20km · 🏃 5km

Olympic

🏊 1.5km · 🚴 40km · 🏃 10km

70.3 Half

🏊 1.9km · 🚴 90km · 🏃 21.1km

IRONMAN Full

🏊 3.8km · 🚴 180km · 🏃 42.2km

Finish-Time Predictor

Combine swim, T1, bike, T2 and run with a run fatigue adjustment for a total finish estimate.

Know roughly when you will finish before you sign up.

Target Pace Splitter

Enter a goal finish time and get sensible paces and time splits for each leg.

Avoid over-cooking the swim/bike and save time for the run.

Transition Checklist

Auto-generate a T1/T2 gear checklist by distance — checkable and printable.

Swim to bike to run gear layout and flow.

Long-Course Fueling Plan

Carbs/fluid/sodium per hour and a schedule for the bike and run legs by race duration.

The key to not bonking on 70.3 and IRONMAN.

Brick Training Planner

Generate bike-to-run sessions so your body adapts to running on heavy legs.

Triathlon-specific and the most-skipped session.

Deep-dive single-sport tools

Triathlon is won in the transitions, not the single sports

A triathlon is not three separate sports added up — races are often decided in transitions and pace distribution. Save energy in the swim, do not blow up your running legs on the bike, and train to run off the bike. The longer the race, the more conservative the pacing: 70.3 and IRONMAN bike legs are usually held at 65–80% of FTP to save glycogen and neuromuscular capacity for the run. Fueling is built around carbs per hour (often 60–90g/h on long course using glucose+fructose), with fluid and sodium matched to sweat rate. Transitions look like something you cannot train — but a good checklist is free time you leave on the table otherwise.
