Plan your season. Own the calendar.
A well-planned season is half the race won. Our 2026 triathlon calendar covers everything from local sprint events to World Championship qualifiers — plus the guidance to plan around them.
Build your season like a professional
Professionals and elite age-groupers share one habit: they plan their season before they plan their workouts. The A-race (the goal race) sets the training timeline, and everything else — the B-races, the training blocks, the taper — works backward from that date.
The typical mistake? Signing up for every race that looks interesting and arriving at your actual goal race fatigued, undertapered, and wondering why your fitness isn't showing up. More races doesn't equal more fitness.
A healthy triathlon season for most age-groupers includes one A-race, two B-races, and intentional recovery periods. Build around that structure and you'll race your best when it matters most.
How to structure your training blocks
A periodized training plan breaks your season into distinct phases, each with a specific focus. Here's the framework used by elite coaches worldwide.
Phase 1: Foundation
Build aerobic base across all three disciplines. Low intensity, high volume. No race-specific work yet.
- Long slow distance
- Technique development
- Establishing routine
- Mobility and strength
Phase 2: Build
Introduce intensity. Threshold sessions, tempo runs, and longer brick workouts begin. Training load increases.
- Interval training
- Race-pace exposure
- Brick sessions
- Nutrition strategy
Phase 3: Peak
Highest training load of the season. Race simulations, back-to-back long efforts. This is where fitness peaks.
- Race simulations
- Time trials
- Mental preparation
- Gear finalization
Phase 4: Taper
Reduce volume, maintain intensity. Let your body absorb the training and arrive at race day fresh and sharp.
- Reduced volume
- Race-pace sharpeners
- Sleep and nutrition
- Race-week rehearsals

70.3Your season planning checklist
Use this checklist to ensure nothing falls through the cracks. Season planning is the boring work that separates athletes who constantly hit PBs from those who wonder what went wrong.
Choose your A-race (your primary goal race) first
Identify 1–2 B-races for practice and fitness testing
Calculate your training blocks working backward from A-race
Book accommodations for destination races early
Register for all races to lock in entry fees and spots
Plan a post-season recovery week (2–3 weeks off all training)
Assess gear needs before the heavy training season begins
Schedule any bike fitting, physio, or testing sessions
The week before race day — day by day
Race week is a psychological minefield. Here's a proven structure to keep you calm, sharp, and ready to execute on the day that matters.
Final long brick workout — keep it short and sharp
Pack your race bag. Check gear. Nothing new on race day
Short sharpener session — 30 min bike + 10 min run at race pace
Travel day if destination race. Check bike drop-off times
Race registration / packet pickup. Course walk-through if possible
Light 20 min spin + 10 min run. Load up on carbohydrates at dinner
Wake 3 hrs before start. Light breakfast. Transition setup. Breathe.
