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 Encarnación could look like.

Let’s build your race

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

Make the second Costanera lap a useful repeat.

The bike mixes mostly flat road with short rolling rises. Keep the first lap measured so the second tells you what is sustainable before the waterfront run.

Playa San José · swim

Find a rhythm before following the next pair of feet.

Find a sighting rhythm off Playa San José and avoid chasing the swimmer beside you before your breathing settles.

Seed honestly. Settle into rhythm.

Costanera · bike lap one

Keep the rollers inside your effort limit.

Mostly flat roads still bring a few rolling hills. Change gear early and keep the rises within your power limit.

Cap opening effort. Fuel early.

Costanera · bike lap two

Repeat the discipline, then prepare to run.

Use the repeated route to compare effort and finish planned nutrition before T2.

Stay patient. Finish planned nutrition.

Waterfront · first run loop

Settle into the pace you can bring back.

Choose an opening run effort you can repeat along the waterfront.

Easy first aid station. Check posture.

San José Beach · second loop and finish

Lift effort only after a controlled first loop.

If the first loop stayed controlled, build effort towards the San José Beach finish.

Stay tall. Choose the last move late.

What to check in race week

Check the latest swim, bike, run and venue maps for Playa San José and the Costanera. Walk your transition route and compare forecast temperature with the cooling routine you practised before choosing opening run pace.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: Training has to make the Costanera rollers economical and leave enough running durability to return to San José Beach after two loops.

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 Encarnación.
