How to Train for Your First Triathlon
Getting Started in Triathlon
Training for your first triathlon can feel overwhelming. Three disciplines, limited time, and a world of conflicting advice. The good news is that with a structured approach and realistic expectations, most people can be race-ready within 12 weeks.
Choose Your Distance
Start with a sprint distance triathlon: a 750m swim, 20km bike, and 5km run. This is manageable for most people with a reasonable base of fitness, and gives you a taste of the sport without committing to months of heavy training. If swimming is your weakest discipline, consider a super sprint (400m swim) as your first event.
Build Your Weekly Routine
Aim for six sessions per week: two swims, two bikes, and two runs. If that feels like too much, start with one session per discipline and add a second when you feel comfortable. Keep your total weekly training time between 5 and 7 hours during the base phase.
- Monday: Rest day
- Tuesday: Easy 30-minute run
- Wednesday: Swim technique session (30-45 minutes)
- Thursday: Bike ride (45-60 minutes)
- Friday: Rest or light yoga
- Saturday: Longer bike ride (60-90 minutes)
- Sunday: Brick session — short bike followed by a 20-minute run
Essential Equipment
You do not need expensive gear to start. A pair of swim goggles, a roadworthy bike (any type), a helmet, and running shoes are the basics. As you progress, consider a triathlon suit for race day and a turbo trainer for indoor bike sessions during winter.
Race Day Tips
- Lay out all your kit the night before and practise transitions at home
- Arrive at the venue at least 90 minutes before your wave start
- Start the swim at a comfortable pace — the first 200 metres are always the hardest
- In transition, keep things simple. Speed comes with experience
- Run your own race. Do not compare yourself to experienced triathletes
Your first triathlon is about finishing, not competing. Focus on enjoying the experience and learning from it. Every triathlete remembers their first race — make it a good memory.
