IRONMAN 70.3 Ohio.
Your best day in Cedar Point.

Sandusky Bay first. Then a flat 90 km through Erie and Sandusky Counties before two downtown loops decide whether the bike really was fast.

What could you race?

I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Cedar Point could look like.

Let’s build your race

Your age and race category help me estimate where that performance could place you. They don’t determine how fast I think you can race.

Change units

Ohio makes restraint entirely your job.

There is almost no terrain to tell you when to ease off. The better race is the one where the bike feels repeatable all the way back to Sandusky and the second run loop still belongs to you.

Jackson St Pier · Sandusky Bay

Seed where you can swim, not where you hope to swim.

Start with athletes swimming your pace and use the opening to settle into rhythm rather than fight for position.

Seed honestly. Settle into rhythm.

Erie and Sandusky Counties · outbound

Keep the cheap speed cheap.

With only gentle gain to contend with, it's easy to override on this flat farmland course. Hold your number regardless of how easy it feels.

Cap opening effort. Fuel early.

Rural Ohio · return to Sandusky

Finish the bike without needing recovery.

Finish planned nutrition and hold effort through the remaining flat miles before the two-loop run.

Stay patient. Finish planned nutrition.

Downtown Sandusky · first loop

Treat lap one as permission to race lap two.

Let the downtown opening feel easy, not fast.

Easy first aid station. Check posture.

Downtown Sandusky · second loop

Use the flat road only after the effort has held.

Only progress once the first loop has held together.

Stay tall. Choose the last move late.

What to check in race week

Confirm the final Sandusky swim start and water conditions, then look at wind across the open farmland and the latest downtown run map. Set the bike ceiling before race morning so easy speed never becomes an excuse to raise it.

Make your finish prediction and I can send this plan to you in race week.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: Train long, uninterrupted flat riding at a disciplined effort, practise fuelling without climbs as reminders and rehearse running well when the bike split felt deceptively easy. Ohio rewards athletes who can manufacture restraint.

I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Cedar Point.
