One of the quickest ways to derail your Ironman 70.3 isn’t a mechanical problem, poor nutrition, or even a lack of fitness.
It’s chasing another athlete.
You’ve probably experienced it.
You’re riding comfortably, sticking to your planned effort, when another competitor comes past.
They look smooth.
They look strong.
Without even thinking, you increase your effort to stay with them.
For a few minutes, everything feels fine.
But Ironman 70.3 isn’t won in those few minutes.
It’s won by the athletes who can maintain their effort for the entire race.
The Trap of Comparison
It’s natural to compare yourself with the athletes around you.
Racing is competitive by nature.
But the athlete overtaking you doesn’t know your training.
They don’t know your fitness.
They don’t know your race plan.
And you certainly don’t know theirs.
Perhaps they’re having the race of their life.
Perhaps they’re riding far above their target power.
Perhaps they’re in a different age group.
Or perhaps they’re making a mistake you’ll see the consequences of later.
The point is simple:
Their race has nothing to do with yours.
Your Plan Exists for a Reason
You didn’t spend weeks or months training just to abandon your strategy because someone rode past.
Your pacing plan is based on your fitness, your experience, and your goals.
If you’ve determined that a certain power output, heart rate or perceived effort is sustainable, trust it.
A brief surge to stay with another rider might not feel significant at the time.
But endurance racing rewards consistency far more than short bursts of speed.
Every unnecessary acceleration uses energy you’ll wish you still had later.
Think Beyond the Bike
The bike leg is only one part of an Ironman 70.3.
Every decision you make on the bike affects the run.
Ride too aggressively and your legs will remind you the moment you leave T2.
A common sight during any Ironman 70.3 is watching athletes who flew past on the bike begin walking during the run.
They weren’t slower athletes.
They simply spent too much energy too early.
The goal isn’t to ride the fastest bike split you can manage.
The goal is to complete the fastest overall race you can achieve.
Ride Your Numbers
Whether you train using power, heart rate or perceived effort, trust the numbers you’ve practised.
When another athlete passes you, ask yourself one question:
“Am I still riding at the effort I planned?”
If the answer is yes, let them go.
If your effort is below target because of a headwind, terrain or another reason, adjust accordingly.
But never change your strategy simply because someone else appears stronger.
Patience Pays Off
One of the most satisfying moments in an Ironman 70.3 is passing athletes during the run who overtook you earlier on the bike.
Not because you’re racing against them.
Because your patience has paid off.
You stayed disciplined.
You trusted your preparation.
You rode your own race.
That discipline gives you the opportunity to finish strong while others are struggling.
Practise Discipline in Training
Race execution starts long before race day.
During training, practise resisting the urge to surge.
Ride steady when others accelerate.
Stay within your planned effort on climbs.
Finish workouts knowing you could have pushed harder if needed.
These habits become automatic when the pressure of race day arrives.
Final Thoughts
There will always be someone riding faster.
There will always be someone who looks stronger.
That’s not the athlete you need to worry about.
The only race plan you can control is your own.
Trust your training.
Trust your pacing.
Trust the process.
Because Ironman 70.3 rewards discipline far more often than aggression.
Ride your race.
And let everyone else ride theirs.
