Questions and answers

Common questions

How does a corporate swim challenge work?

Teams train together with the preparation programme, then take on the 33.3km distance across four days at an UltraSwim 33.3 event, fully supported throughout.

Do team members need to be strong swimmers?

A reasonable base helps, but the programme builds endurance and open water skills from each swimmer's current level.

What does it build for a team?

Resilience, trust and a shared achievement that lasts far longer than a typical away day or offsite.

What is included?

All inclusive packages from 1,800 euro cover hotel, meals, swim support, transfers, the finisher dinner and a full preparation programme.
