The early season is exciting. Motivation is high, races are on the calendar and it finally feels like go time. But from a coaching perspective, this is also when many athletes unknowingly make decisions that limit their progress or derail their season entirely.
Whether you’re new to triathlon or a seasoned age grouper, here are the most common early-season mistakes we see and what to do instead.
Racing Your Training (and Everyone Else)
Early season fitness can be deceptive. A few solid weeks of training can make you feel fit, but fitness built too quickly without structure rarely lasts.
What to avoid:
- Turning every session into a race
- Chasing paces or watts you hit at the end of last season
- Letting ego dictate effort
What to do instead: Treat the early season as foundation building time. Focus on controlled efforts, repeatability and good technique. The athletes who win their season aren’t the ones smashing January workouts, they’re the ones still improving in July and August.
Skipping the Base Phase
Base training isn’t glamorous, but it’s essential. Aerobic development, movement quality and consistency are what allow intensity to be effective later.
What to avoid:
- Jumping straight into high intensity intervals
- Copying advanced programs from pros or influencers
- Believing “no pain = no gain”
What to do instead: Build aerobic capacity, strength and efficiency first. When intensity is layered on top of a strong base, it actually works!…and you stay healthy doing it.
Doing Too Much, Too Soon
More isn’t always better, especially early on.
What to avoid:
- Rapidly increasing volume or intensity
- Adding extra sessions “just because you feel good”
- Ignoring early signs of fatigue or niggles
What to do instead: Progress gradually. Consistency beats heroic weeks followed by forced time off. A well structured plan balances stress and recovery so adaptation can happen.
Neglecting Strength and Mobility
This is one of the first things athletes drop and one of the biggest regrets later in the season.
What to avoid:
- Waiting until you’re injured to add strength work
- Assuming swim/bike/run is enough
What to do instead: Early season is the best time to build strength, improve mobility and correct imbalances. This supports better performance and reduces injury risk when training load increases.
Training Without a Clear Purpose
Random training leads to random results.
What to avoid:
- Piecing together workouts from social media
- Training hard but without direction
- Not knowing why you’re doing a session
What to do instead: Follow a plan that aligns with your goals, schedule and ability. Every session should have a purpose and fit into a bigger picture.
